The self-treatment will mobilise the stiff and often immobile thoracic spine and lower back, alleviate headaches, aches and pains and ultimately improve performance. The process involved postural assessment in 3 planes (saggital, frontal and transverse) and techniques (3 ilterations) of treatment; these may involve some corrective exercises and soft tissue work.

The rack can be purchased and is specifically designed to achieve mobility (Refer to http://taichihealthfitness.blogspot.com/ for the full descriptions and purchases).

■ It allows you to stretch the anterior muscles of the chest and shoulders that are deemed short and often inflexible due to poor posture.

■ It mobilises the thoracic spine, increasing your ability to extend and rotate through this important area.

■ Mobilising the thoracic region helps increase the available movement in the shoulder and pelvic region, allowing us to move more freely and efficiently.

■ Serves as treatment equipment and later as fitness equipment during the maintenance phasse. Enhance quality of life over life cycle

Many good results and testimontials have been received from Sedentary adults, Yoga, Pilates and Tai Chi practioners / instructors, cyclists, runners, swimmers, golfers, tennis players, badminton players, dancers, scoliosis clients, clients with low back pain / hand numbness / nerves impingement etc.

Effects of Sport Massage

Recent advances in sports and exercise science have highlighted the potential of sports massage to improve circulation and accelerate recovery from activity and injury (Benjamin & Lamp, 2005). Sports massage from skilled therapist (Moraska, 2007) can significantly improve the condition of the muscles of any participants. The deep massage, pumping and stroking movement improve circulation, remove waste products and improve elasticity on physical and physiological aspect; and the psychological benefits include invigoration and reduction of mental tension (Weerapong, Hume, & Kolt, 2005).

To maximize the benefits, massage treatment are administered on:
1. Pre-event
2. During event
3. Post-event (Directly after event)
4. Post-event (several hours and days after event)
5. Restoration/rehabilitation
6. Training/conditioning

The massage techniques used are stroking manipulation - effeurage (flushing), pressure manipulation - petrissage (kneading, picking, wringing, rolling) and squeezing/pressing, friction, tapotement (plucking, hacking, cupping, tapping, pounding etc.), vibration/shaking, acupressure and trigger pointing (Riggs, 2007; Watt, 1999).

Delayed-onset muscle soreness (DOMS) describes muscle pain and tenderness that typically develop 12 - 24 hours after such exercise (Clarkson, Nosaka, & Braun, 1992) and subsides generally within 4 to 6 days; and consist of predominantly eccentric muscle actions, especially if the exercise is unfamiliar. Although DOMS is likely a symptom of eccentric-exercise–induced muscle damage, it does not necessarily reflect muscle damage.

Sports massage of minimum 10 minutes was effective in alleviating DOMS by approximately 30% and reducing swelling, but it had no effects on muscle function (Bakowski, Musielak, Sip, & Bieganski, 2008; Zainuddin, Newton, Sacco, & Nosaka, 2005).

Gait and posture observation are normally done on the first appearance of the subject. Posture will always play an important role in performance and sense of well-being. “Postural distortion is the beginning of the disease process”, proclaimed by Han Selye, MD, Nobel Prize laureate. This will give a general direction for the therapist to work on.

DIY Taichi Music

Integrate MP3 Player with Speaker Option for Taichi Individual

The MP3 hardwares for individual were bulky previously, especially when there were incorporated with the speaker option. It is affordable and user friendly now and is the good time that we integrate health and fitness solutions to peoples of all ages.

The integrated solution is far more than exercise with music (Lawrence, 2004) and in sports psychology, it is called disassociation (Weinberg & Gould, 2007) which decrease in fatigue (Kirby & Murphy, 2005) and monotony of training and leads to motivation. Appropriate Music (Smith & Widmer, 2004) is used as a dissociative strategy to improve exercise capacity in patients (Macintyre, Bloomer, Provan, & Sturrock, 2001); others used it as a emotional regulation strategy (Bishop, Karageorghis, & Loizou, 2007). The evidence regarding the beneficial effects of music on performance during submaximal endurance exercise suggested that it was probably helps by suppressing cardiovascular and metabolic responses (Fatouros et al., 2005).

The hardwares are light with speaker option to minimize the disadvantage of headphone wires crossing the body to the ears. It also act as the thumb drive that can plug into portable CD/Radio player for group exercisers usage. Other applications such as with the earphone features, sound recording and radio are added advantage.

Taichi MP3 Walking/Running

Humans are walking and running species. Refer to Fitness Running Book (Brown & Henderson, 2003) and Lore of Running (Noakes, 2003) for training and physiological references.

Taichi circuit training

Cardiorespiratory Circuit of various exercises (with and without equipment) and durations (customisation for Taichi specific) incorporating with music depending on individual or group requirements. Circuit system for resistance training - example: exercises performed in succession with minimal rest (15 to 30 sec) between exercises; about 10 to 15 repetitions of each exercise are performed per circuit with resistance of 40 to 60% of 1RM (Fleck & Kraemer, 2004).

Taichi sports performance

- Mental Rehearsal and Training (Weinberg & Gould, 2007) including imagery (Hecker & Kaczor, 1988). Technique imagery includes imagery related to the execution of proper body positioning and form while exercising (Munroe-Chandler & Gammage, 2005),
- Positive affirmation statement
- Rest Recovery strategy
- Injuries Recovery etc.

Taichi with Music

Effects of Music on Taichi

Taichi exercise is of low to moderate intensity similar to when jogging or walking, listening to a favourite piece of music might decrease the influence of stress caused by fatigue, thus increasing the ''comfort'' level of performing the exercise; music evokes a ''distraction effect'' during low intensity exercise (Yamashita, Iwai, Akimoto, Sugawara, & Kono, 2006).
Taichi exercise with preferably using medium tempi music program was the most appropriate for an exercise intensity of 70% maxHRR (C. Karageorghis, Jones, & Stuart, 2008).

Influences by type of music and personal factors

Potteiger, Schroeder and Goff (2000) had done the research on the ratings of perceived exertion (RPE) influenced by difference type of music. Fast upbeat music, classical music, self-selected music, and no music were used; and heart rate, peripheral RPE, central RPE, and overall RPE were measured every 5 min during exercise (20 min of moderate exercise). There were no significant differences found in heart rate among the four conditions indicating similar exercise intensity during each condition. Each type of music resulted in a reduced peripheral, central, and overall RPE when compared with the no-music condition. The data indicated that different types of music could act as an effective passive distractor during exercise and were associated with lower ratings of perceived exertion. Exercise with most preferred music condition reported the highest levels of dissociation (Dyrlund & Wininger, 2008).

Participants reported a preference for both medium and fast tempo music at low and moderate exercise intensities and for fast tempo music at high intensity. Only partial support was found for the expected linear relationship between exercise intensity and music tempo preference (C. I. Karageorghis, Jones, & Low, 2006).

When evaluating the relationships between affect intensity, age and importance of musical components, rhythm response components (rhythm, tempo, beat) were rated as most important. Gender differences in perceptions of musical are importance. Women rated the importance of melody significantly higher than did men, whereas men gave more importance to music associated with sport. Affect intensity was found to be positively and significantly related to the perceived importance of melody, lyrical content, musical style, personal associations and emotional content. Results suggest that the needs to be sensitive to personal factors when choosing music to accompany exercise (Crust, 2008).

Music as a healing art

Complementary therapies and healing practices such as Taichi with music and imagery have been found to reduce stress, anxiety, and lifestyle patterns known to contribute to cardiovascular disease (Kreitzer & Snyder, 2002).

When using relaxing music, it has a better effects on aerobic exercise-induced fatigue, helps in rehabilitation of cardiovascular, central, musculoskeletal and psychological fatigue and the promotion of the regulatory capability of the kidneys (Jing & Xudong, 2008).
There is increasing evidence of the importance of regular mental and physical exercise to maximize overall health and functioning in older adults. However, many individuals find that reduced strength or disabilities prevent them from participating in the kinds of exercise they enjoyed when they were younger. Music can provide the important benefits of both mental and physical stimulation to even frail older adults (Sorrell & Sorrell, 2008).

Resource for Diabetic Recipes

We are seeing an alarming increase in numbers with diabetes. To help diabetic clients to eat more healthy foods, here suggests a site www. diabeticrecipes.com (you can find this site in my references link) that has a great resource.




The Pancreas and Diabetes

The most common endocrine disorder, and a serious public health problem, is diabetes mellitus, a failure of the body cells to use glucose effectively. The excess glucose accumulates in the blood, causing hyperglycemia. Increased urination (polyuria) marks the effort to eliminate the excess glucose in the urine, acondition termed glycosuria. The result is dehydration and excessive thirst (polydipsia). There is also weakness, weight loss, and extreme hunger (polyphagia). Unable to use carbohydrates, the body burns more fat. This leads to accumulation of ketone bodies in the blood and a shift toward acidosis, a conditiontermed ketoacidosis. If untreated, diabetes will lead to starvation of the central nervous system and coma. Diabetic patients are prone to cardiovascular, neurologic, and vision problems, infections, and, sometimes, renal failure.

There are two types of diabetes mellitus. Heredity seems to be a factor in the appearance of both. Type 1, also called juvenile-onset or insulin-dependent diabetes mellitus (IDDM), usually appears in children and teenagers. Globally, an estimated of 500,000 children under the age of 15 live with Type 1 diabetes. It is caused by a failure of the pancreatic islets to produce insulin, resulting, perhaps,from auto immune destruction of the cells. Because insulin levels are very low or absent, patients need careful monitoring and administration of this hormone. Blood sugar level may be tested multiple times during the day, and insulin may be given in divided doses by injection or by means of an insulin pump that deliversthe hormone around the clock (continuous subcutaneous insulin infusion; CSII). Diet must be carefully regulated to keep glucose levels steady. Insulin is obtained from animals and is now also made by genetic engineering.

Type 2 diabetes mellitus, also called adult-onset or non–insulin-dependent diabetes mellitus (NIDDM), accounts for about 90% of diabetes cases. Type 2 diabetes is initiated by cellular resistance to insulin. Feedback stimulation of the pancreatic islets leads to over production of insulin and then to reduced insulin production by the overworked cells. Metabolic syndrome (also called syndrome X or insulin resistance syndrome) is the term now used to describe a state of hyperglycemia caused by insulin resistance in association with some metabolic disorders, including high levels of plasma triglycerides (fats), low levels of high density lipoproteins (HDLs), hypertension, and coronary heart disease.

Most cases of type 2 diabetes are linked to obesity, especially upper body obesity. Although seen mostly in older people (hence the name adult-onset diabetes), the incidence of type 2 diabetes is increasing among younger generations (is growing alarming rate in children), presumably because of increased obesity, poor diet, and sedentary habits. Exercise and weight loss for the overweight are the first approaches to treating type 2 diabetes, and these measures oftenlead to management of the disorder. Drugs for increasing insulin production or improving cellular responses to insulin may also be prescribed, with insulin treatment given if necessary.

Gestational diabetes mellitus (GDM) refers to glucose intolerance during pregnancy. This imbalance usually appears in women with a family history of diabetes. Women must be monitored during pregnancy forsigns of diabetes mellitus, especially those with predisposing factors, because this condition can cause complications for both the mother and the fetus. Again, ensuring a proper diet is a first step to management, with insulin treatment recommended if needed.

Diabetes is diagnosed by measuring levels of glucose in blood plasma with or without fasting and by monitoring glucose levels in the blood after oral administration of glucose (oral glucose tolerance test; OGTT). Categories of impaired fasting blood glucose (IFG) and impaired glucose tolerance (IGT) are stages between anormal response to glucose and diabetes.

Excess insulin may result from a pancreatic tumor, but more often it occurs after administration of too much hormone to a diabetic patient. The resultant hypoglycemia leads to insulin shock, which is treated byadministration of glucose.

Here are some signs of diabetes to look out for:
- Frequent urination
- Excessive thirst
- Increased hunger
- Weight loss
- Tiredness
- Lack of interest and concentration
- Blurred vision
- Vomiting and stomach pain (often mistaken as the flu)

Biopsychological Integration

Biopsychological integration is a holistic approach to enhance a person’s performance, health and process of rehabilitation. The body qualifies as a system, and includes the immune and nervous system, which consist of tissues and cells. Our family is a system, and so are our community and society. As a systems, they are entities that are dynamic (consistently changing) and they have components that interrate, such as by exchanging energy, substances and information.

To illustrate how the interacting biopsychological systems concept works, let’s assume that the person having chronic pain on knee and inherited some factors that affect his weight (biological system). The meals in the family (social system) and foods taken in the family and from the hawker centres usually contain high fat and high kilo-joules foods. He preferred to engage in sedentary activities such as playing manjong, slow walk once a week and watching television (psychological system).

We can also use the biopsychological model also as a guide to promote people’s health and recovery from illness. In the biological system, understanding the aetiology of the patellofemoral joint syndrome (weaknesses of related muscles, the postural problems etc.) is important to provide immediate appropriate treatment. Weight control management through body composition monitoring on energy balance between the dietary intake and exercise energy expenditure is essential.

By using the psychological methods such as goal setting, relaxation and imagery in Taichi exercise programming (correction on increased lumbar lordosis, excess pelvic tilt, poor Taichi motor movement; and engage in the moderate Taichi/walking exercise daily etc.) to increase motivation, self efficacy and exercise adherence.

Peoples are doing Taichi practices individually, in small groups and big groups (e.g. in the Yew Tee RC, coaching by NewAgeTaichi); they have bonding, multi-racial and social harmony. People who have a high degree of social support from family, friends, instructors and coaches are healthier and live longer than people who do not.

Cardiovascular Disease (CVD) Reversal

Endothelial dysfunction
Scientists had recognised that the endothelial wall of the coronary arteries plays a vital role in vascular health. Aging and hypertension are two independent cardiovascular risk factors that have been shown to exhibit increased endothelin-1 system activation (Stauffer, Westby, & DeSouza, 2008). In addition, smoking, elevated low-density lipoprotein (LDL) cholesterol, elevated blood glucose and inflammation attribute to the endothelial dysfunction, the abnormal or impaired physiological function of the biochemical processes carried out by the endothelial cells lining the inner surface of the artery walls. Endothelial dysfunction, particularly vasomotor dysregulation occurs early in the atherosclerotic process, contributes to disease development and progression, and can trigger acute cardiovascular events (Van Guilder, Westby, Greiner, Stauffer, & DeSouza, 2007).

Effect of exercise and dietary on blood lipids
High density protein (HDL) cholesterol increases nitric oxide (a potent vasodilation) production, inhibiting blood cell adhesion to vascular endothelium and reducing platelet aggregability and coagulation (Calabresi, Gomaraschi, & Franceschini, 2003) and hence reverses cholesterol transport, removing cholesterol from the arterial wall.

The positive effects of regular exercise are exerted on blood lipids at low training volumes and accrue so that noticeable differences frequently occur with weekly energy expenditures of 1200 to 2200 kcal/wk. It appears that weekly exercise caloric expenditures that meet or exceed the higher end of this range are more likely to produce the desired lipid changes (improved in HDL cholesterol concentration). This amount of physical activity, performed at moderate intensities, is reasonable and attainable for most individuals and is within the American College of Sports Medicine's currently recommended range for healthy adults (Durstine et al., 2001). Durstine, Grandjean, Cox, & Thompson (2002) had indicated similar results unless dietary fat intake was reduced and body weight loss was associated with the exercise training program, or both.

Aerobic fitness
Aerobic fitness, not merely physical activity, is associated with a reduced risk of cardiovascular disease. Vigorous intensity exercise has been shown to increase aerobic fitness more effectively than moderate intensity exercise, suggesting that exercise performed at a vigorous intensity appears to convey greater cardioprotective benefits than exercise of a moderate (Swain & Franklin, 2006).

Regular and habitual aerobic exercise
Regular and habitual aerobic exercise can prevent the age-associated loss in endothelium-dependent vasodilation (arterial aging) and restore levels (preserving vascular function) in previously sedentary middle aged and older healthy men. This represent an important mechanism by which regular aerobic exercise lowers the risk of cardiovascular disease (DeSouza et al., 2000; Seals, Desouza, Donato, & Tanaka, 2008; Smith, Hoetzer, Greiner, Stauffer, & DeSouza, 2003).

Taichi is an aerobic exercise and is suitable for participants of different ages and gender to improve their functional capacity (Lan, Chen, & Lai, 2004).

Preventive and middle age risk-free
Preventing coronary artery disease (CAD) development since teens, 20s or 30s is essential rather than try to reverse it later. Research done by Stamler and others (2000) on a total of 11,017 men aged 18 through 39 years screened in 1967-1973; men with favourable baseline serum cholesterol levels (<200 mg/dL [<5.17 mmol/L]), had an estimated greater life expectancy of 3.8 to 8.7 years.

Adults who had low risk factors in middle age demonstrated a significantly higher quality of life in older ages compared with those who had three or more risk factors (risk factors increase, quality of life decreases)(Daviglus, Lloyd-Jones, & Pirzada, 2006). It appears that 50 may be the turning point; individuals who are able to read this age with no risk factors have markedly higher survival rates than those with any combination of risk factors (Janot, Dalleck, & Bushman, 2008).

Taichi – Functional Anatomy

In theory, myofascial slings have no beginnings and no ends. Depending on movement, different sling activate different time. Myofascial slings (most familiar, studied and commonly used) are:
A. Anterior oblique system
B. Posterior oblique system
C. Posterior longitudinal system


Examples of Myofascial Lines
A. Superficial Back Line
B. Superficial Front Line
C. Lateral Line
D. Spiral Line


The pectorialis --> internal oblique --> gluteus medius slings form the spiral and function line; similar to TaiChi movement for 外三合 - 肩与胯合, 时与膝合, 手与足合. Symmetrical line for both side of the body such as for the spiral line is important and any unsymmetrical can cause common postural problem (head shifted/tilted to one side).

Discussion
The warm-up (approximately 10 minutes) was conducted using the elliptical cross trainer with the same uphill and downhill profile for forward and backward movement. The maximum heart rate for the backward motion was about 1.11 times higher (larger cardiovascular exertion) than the forward motion; this indicated that the energy expenditure was higher and suitable for aerobic endurance improvement with proper exercise programming. This was similar to the findings done on the some of past scientific research (Hooper et al., 2004; Minetti & Ardigo, 2001). The energy cost for thus for the backward was greater than forward motion (Williford, Olson, Gauger, Duey, & Blessing, 1998)

Regarding the energy cost of the Taichi practices, the Chen 56 steps > 42 competition set > Yang 40 steps > 24 steps; the exercises were using the same baseline heart rate for comparison purpose. The differences were due to the complexity and difficulties (e.g. Chen 56 steps has more eccentric & propulsive movements) level of the set. By practising the various sets or repeated the same set continuously (duration) will allow the subjects to exercise at moderate intensity level.

Taichi is an exercise with moderate intensity, and its exercise intensity is similar across different ages in each gender (Lan, Chen, & Lai, 2008).

Comprehensive Lifestyle Changes Impact Cancer Genes

Mind-Body Lifestyle Changes Impact Cancer Genes

Epidemiological and prospective studies indicate that comprehensive lifestyle changes may modify the progression of prostate cancer (Ornish et al., 2008).

Materials and Methods
Study subjects
- 30 males (mean age of 62.3 years (range 49–80)) with prostate cancer. All had low-risk prostate cancer and had refused immediate surgery, hormone therapy or radiation. Instead, they participate in the lifestyle program including of periodic monitoring of tumors to track any growth.

Lifestyle intervention
- 3 month comprehensive lifestyle modification was prescribed
1. Dietary change
Vegan diet
Supplement: Soy, fish oil, vitamin E, selenium and vitamin C
2. Moderate exercise
Walk 30 minutes a day, 6 days a week
3. Stress management
Yoga-based stretching
Breathing
Meditation
Imagery
Progressive relaxation
4. Group support

Discussion

After 3 months, the researchers observe changes in gene expression that affected the tumors: genes that promoted the cancer were no longer active or were less active, and genes that helped fight the cancer were switched on. More people with all ages are able to change and adherence to the program. These findings suggest that never be too old to make changes that positively affect your health (Archer, 2008).

This lifestyle intervention is related to the lifestyle filter in the hour glass model (Gallahue & Ozmun, 2006) in article presented on 15th Oct ’08. Both the moderate exercise and stress management can possible be substituted by Taichi if done correctly to achieve the moderate exercise intensity and psychological benefits.

Overweight & Obesity

An introduction: statistics on the growing trend to obesity in Asia Pacific region, number of overweight/obese in Singapore

Global and United States
Obesity is an excess body weight due to fat deposition as compared to set standards of body weight (Afridi & Khan, 2004). It is a single chronic disease that trigger many kinds of diseases such as type 2 diabetes that leading to cardiovascular disease and cancers. Type 2 diabetes is estimated to be 30 million in US and worldwide estimation of 120 million (Amos, McCarty, & Zimmet, 1997). The prevalence of diabetes for all age-groups worldwide was estimated to be 2.8% in 2000 and 4.4% in 2030 and the total number of people with diabetes is projected to rise from 171 million in 2000 to 366 million in 2030; the prevalence of diabetes is higher in men than women, but there are more women with diabetes than men and increase in proportion of people > 60 years of age (Wild et al., 2004). Similar trends also on childhood overweight and obesity (Wang & Lobdtein, 2006)

Asia Pacific region
There has been dramatic increase of obesity in Asia-Pacific region in recent years. In the Republic of North Korea’s National Nutrition Survey 1995, only 1.5% of the population was classified as obese (BMI > 30kg/m^2) and 20.5% overweight (BMI 25-29.9 kg/m^2); in Thailand, 4% were obsess and 16% overweight; in Malaysia, 4.7% of men and 7.7% of women were obese (Inoue et al., 2000).

Singapore
A national committee was appointed in 1991 to review the national health plan for 1990s, followed by the National Healthy Lifestyle programme in 1992 with extensive use of mass media and widespread school, workplace, and community health promotion programme emphasizing healthy diets and regular exercise (Cutter, Tan, & Chew, 2001). The obesity remained unchanged at 6% between 1992 and 1998, but among the Malay women, 11.1% were classified as obese in 1992, and 16.2% in 1998; and the Indian women are 12.5% and 17.5% comparatively (Inoue et al., 2000); the ethnic difference has implications on the acute myocardial infarction (Mak et al., 2003). In the nation health survey 2004 of age between 18 – 69 years, the diabetes rates had slight improvement from 9% in 1998 to 8.2% in 2004 and this corresponds to proportion of adults who exercise regularly increased from 16.8% in 1998 to 24.9% in 2004; no exercising drop from 54.7% in 1998 to 48.1% in 2004 ("National Health Survey 2004", 2005). In the 2005 National Sports Participation Survey (Market Probe-Precision Research Pte. Ltd., 2005), the incidence of “regular sports participants” has risen from 38% in 2001 to 48% in 2005 among adult population (i.e. aged 15 years and above). Nevertheless, the overweight and obese are still relatively high, and are at risk of obesity related diseases. To further improve the obesity condition, Ministry of Education policy requires the schools to have at least 70 minutes of physical education per week to equip young people to be well prepared starters in taking ownership and responsibility for their own health and well-being through initiatives for PRIDE (personal responsibility in daily effort) and PLAY (participation in lifelong activity for youths) programme (Chia, 2007).

Health cost
Davis, Knuiman, Hendrie, and Davis (2006) estimated the cost of diabetes for both individual and society is $A636 million based on type 2 diabetes in 2000 and projection to 2051; and as the result of aging population it will double the cost contributing to financial burden and funding to rising health-care costs. This trigger for the health and fitness industries and demand for gyms, weight-loss centres, health clubs and diet solutions.

A discussion on health problems of excess weight

Industrialization
An effect of acculturation or modernization and attributed with the reduced levels of activity increasing the prevalence of obesity. As the populations become more westernized, dietary composition changes to include more saturated fat, less fibre and exposure to obesogenic environment; and these lead to more energy dense diets causing higher energy intake leading to positive energy balance. Prentice and Jebb (2004) in his research explain the imbalance between the effectiveness of the hunger and satiety signals leads to an asymmetry in appetite control that helps to explain why current life styles create such a high level of susceptibility to obesity in most individuals. In Asia and especially Chinese ethnic group, obesity was and some cases remains, a symbol of wealth and increased social status (Dowse, Hodge, & Zimmet, 1995). Other factors of influences are occupation and education, as well as stresses from urban society.

Genes
Nevel J.V. in 1962 (as cited in Andrew, Alexandra, Blakemore, & Philippe, 2006) proposed the “thirty gene” hypothesis had a selective advantage in populations that frequently experience starvation. In today’s obesogenic environment with just only few decades that the industrialized world has done from a calorie-poor to a calorie-rich environment; these genes might be those that “overreact” not just over weight, but extremely obese. Genetics factors that affect metabolism and appetite determines to about 25% of the variation among people in percentage body fat and body mass; a larger percentage of variation relates to a transmission (cultural) effect (McArdle, Katch, & Katch, 2005). Genetic makeup does not necessary cause excessive weight gain but however in the presence of powerful environmental influences, it lowers the threshold of gaining weight. Being obese does not mean being ill and , indeed, it is likely that very good health is required to establish and to maintain obesity (Andrew, Alexandra, Blakemore, & Philippe, 2006).

Problems with excess weight
Diabetes mellitus is one of the mostly commonly encountered diseases that impaired glucose tolerance to type 2 diabetes (Dunstan, AO, Slade, & Harper, 2003), it related morbidities include diabetic retinopathy, neuropathy and cardiovascular disease (Wee, Ho, & Li, 2002). Adults with diabetes have heart disease increased to 4.5 times higher than those without diabetes and similar trend held with respect to stroke (Peck, 2002). Although much emphasis is placed on the link between obesity and life threatening health problems like coronary heart disease (CHD) and diabetes, another health consequence of obesity is knee osteoarthritis (OA) and disabling knee pain (risk is 7-10 times higher than non-obesity); it happens in older adults and about 10% of the world’s population aged 60 or older have significant health problem attributed to OA (Jinks, Jordan, & Croft, 2006). It is normally recommended that the person with knee pain and disability to use weight reduction to manage and not to alleviate these symptoms. The comorbidities of obesity include hypertension, elevated blood sugar, pulmonary dysfunction including asthmas and sleep apnea, psychiatric problems like depression and eating disorders, postmenopausal breast cancer, pancreatic cancer, gastrointestinal disorders including gallstones (risk of 5 times higher if BMI > 40), and elevated total cholesterol (high LDL and low HDL) and increase psychological burden; all these heighten an over-weight individuals exposing to risk of poor health (McArdle, Katch, & Katch, 2005).

Death due to obesity
The estimated number of death attributed to obesity per se ranges between 280,000 and 325,000; which was more than 80% of the estimated obesity-attributable deaths occurred among individuals with body mass index of more than 30kg/m^2 without taking the smokers and never-smokers into consideration because cessation of smoking increase weight gain (Allison, Fontaine, Manson, Stevens, & VanItallie, 1999). This was based on the 1991 analysis because of availability of population (1990 US census) and mortality statistics. In Singapore, the obesity had risen from 6% in 1998 to about 7% in 2004; high blood cholesterol of about 18% and high blood pressure of about 20% in 2004 ("National Health Survey 2004", 2005). Diabetes mellitus was 9%, the sixth most common cause of death in 1998, accounting for 2.2% of annual total mortality (Wee, Ho, & Li, 2002).

Monitor own body mass
When the new BMI classification report released on 16th March 2006 in Singapore, many had turned up to the measuring machine islandwide to measure their body mass index (BMI); the new classification indicated that the weight was acceptable at 18.5-23, slight over-weight from 23-25, over-weight from 25-30 and obese for >30 (Forss, 2006). The point to take note on BMI is that they is a possibly of misclassifying someone as overweight to large-size field athletes, bodybuilders, weightlifters, upper-weight-class wrestlers, and professional football players etc (McArdle, Katch, & Katch, 2005).

A critical Review of the usefulness of low carbohydrate, high protein diet: what are they, why are they popular, suitability for weight loss, long term issues/success

Popularity
Some low carbohydrate and high-protein diets are Atkin, Zone, Protein Power, Sugar Busters and Stillman. This low carbohydrate, high protein diets have recently been proposed as a “new” strategy for fast weight loss due to the increased dietary thermogenesis, increased satiety and a decreased in subsequent energy; which made the high protein intakes diet book popular. More than 10 million copies of Alkins diet books have been sold. Researchers Yancy, Olsen, Guyton, Bakst and Westman (2004) indicated a weight loss of 12.9% after 24 weeks for people using the Atkins diet. Other research by Brehm, Seeley, Daniels, and A.D'Alessio (2003) shown similar outcome result of 8.5 ± 1 kg versus 3.9 ± 1 kg (about 2 times as compare to low fat diet) weight loss for 6 months of trial. Zone diet recommends that the protein should account for 30% or more energy and this is regarding high because it is twice the typical intake or 12 – 15%. These diets are generally associated with higher intakes of total fat, saturated fat, and cholesterol because the protein is provided mainly by animal source.

Suitability for weight loss, long term issues/success
Nutrition Committee of the American Heart Association (AHA), noted that high protein diets may not be harmful for most healthy people for a short period of time, but there is no long term scientific studies to support their overall efficacy and safety (Jeor et al., 2001). The Nutrition Committee does not recommend high protein diets because they do not provide the variety of foods needed to adequately meet nutritional needs. In high protein diet, weight loss is initially high due to fluid loss related to reduced carbohydrate intake, overall caloric restriction, and ketosis-induced appetite suppression; ketosis - the body's natural response to starvation. Ketosis is triggered by low insulin levels in the blood, which can result from restricted carbohydrate intake, and can lead to a loss of appetite, another reason why high-protein dieters are often successful in shedding pounds in the short run (Eisenstein, Roberts, Dallal, & Saltzman, 2002). Weight loss benefited the effects on blood lipids and insulin resistance. Promoters of high protein diets promise successful results by encouraging high protein food choices that are usually restricted in other diets, thus providing initial palatability, an attractive alternative to other weight-reduction diets that have not worked out for variety of reasons for most individuals. High protein diets are not recommended because they restrict healthful foods that provide essential nutrient and individuals who follow these diets are therefore at risk for compromised vitamin and mineral intake, as well as potential cardiac, renal, bone, and liver abnormalities (Jeor et al., 2001). It also increase urinary excretion of oxalate, a compound that combines primarily with calcium to form kidney stones (Eisenstein, Roberts, Dallal, & Saltzman, 2002). High levels of urinary calcium with the diets also indicate that decreased in calcium balance and increased risk for bone loss. In addition, high protein diet usually failed to contain the highest quality amino acid mixture and lacked required vitamins and minerals particularly copper; a negative balance coincides with electrocardiographic abnormalities and rapid heart rate (Fisler, 1992). Manninen, in his paper (2004) argue that there were not enough of scientific evidence to support the negative effects. Other evident like the high intakes of meat protein accelerated renal function decline in women who had a mild renal insufficiency at the start of an 11 year study also do support the negative effect (Williams, 2005). Robert H. Eckel, MD, who chairs the AHA Nutrition Committee, warned that Atkins and Protein Power have particularly high intakes of total fat, saturated fat and cholesterol (60% of daily calories from fat), all of which raise the risk of heart disease.

There has never been a ‘weight loss breakthrough’ that simple new idea or product that will make body fat loss easy. AHA guidelines recommend a diet low in fat and high in fruit, vegetables, whole grains and low-fat dairy products. Diets should contain no more calories than necessary to maintain a healthy body weight.

Conclusion

This prevalence obesity rates reflect changes in lifestyle with economics development lead to population growth, aging, urbanization, and physical inactivity. A low carbohydrate, high protein diets have not proven to be effective in long-term weight reduction and they may pose health risks for individuals who stay on them for more than a short time. Diet and lifestyle play a significant role both in development and control of obesity.

There is strong evidence that people who are physically active are at less risk of developing obese related disease such as diabetes than those who lead sedentary lifestyles. Regular exercise of at least 30 minutes of moderate-intensity activity on most, preferably all days of the week and increased the leisure-time physical activity including planned exercise and sport. A well-rounded physical activity program should include aerobic and strength-developing activities. The education systems under the Ministry of Education umbrella enable the younger generation to take ownership and responsibility for their own health and well-being. When Singapore is moving to become a regional sporting hub in 2011, the environment will create more opportunities for physical activities that support the individuals desired behavioral changes.

Resistance Exercise Reverses Aging in Human Skeletal Muscle

Human aging is associated with muscle atrophy (sarcopenia), weakness and functional impairment, which commence in the fourth decade of life with a rate of strength loss of about 1.0% per year, accelerating with each passing decade (Timothy J. Doherty, 2003). A functionally debilitating sarcopenia affects approximately 7% of adults over 70, and up to 20% over age 80 years (Castillo et al., 2003; Melton et al., 2000).

Healthy older adults show evidence of mitochondrial impairment and muscle weakness, but that this can be partially reversed at the phenotypic level, and substantially reversed at the transcriptome level, following six months of resistance exercise training.

A recent study (Melov, Tarnopolsky, Beckman, Felkey, & Hubbard, 2007), involved before and after analysis of gene expression profiles in tissue samples taken from 25 healthy older men and women who underwent six months of twice weekly resistance training, compared to a similar analysis of tissue samples taken from younger healthy men and women.

The gene expression profiles involved age-specific mitochondrial function; mitochondria act as the "powerhouse" of cells. Multiple studies have suggested that mitochondrial dysfunction is involved in the loss of muscle mass and functional impairment commonly seen in older people. The study was the first to examine the gene expression profile, or the molecular "fingerprint", of aging in healthy disease-free humans.


Exercise Training (Exercise protocol used in the above research)

Resistance exercise training was performed twice weekly on non-consecutive days (Monday+Thursday, or Tuesday+Friday) or 26 weeks (6 months). Prior to, and after each, training session, subjects were required to perform static stretching.

Resistance exercise for each session consisted of 3 sets of 10 repetitions for each of; leg press, chest press, leg extension, leg flexion, shoulder press, lat pull-down seated row, calf raise, abdominal crunch, and back extension and 10 repetitions for arm flexion and arm extension.


TaiChi Training Concept

Resistance training (such as circuit training programme for small group) is used in the physical preparation stage at difference days of the week and is difference from the aerobic & endurance training days.

The Psychological Benefits of Exercise and To Enhance the Benefits

Introduction

The President’s Council on the Physical Fitness & Sports (as cited in Cox, 2007, p. 393) “ If exercise could be packed into a pill, it would be the single most widely prescribed and beneficial medicine in the nation”.

In the Singapore Sports Council’s National Sports Participation Survey (Market Probe-Precision Research Pte. Ltd., 2005) released on March 2005, it shows 48 percent of 8,007 respondents exercise at least once a week as compared to 38 percent on 2001. Of these 40 percent said that they had no time for sports due to work commitments. It was significant that 24 percent of the non-exercisers blamed lack of time due to work (for making them too exhausted), lack of interest and family commitment that gobble up their time. Almost 90 percent listed watching TV or DVD movies at home as their choice of leisure activity on weekdays. Sports (36%) was ranked behind reading (48), listening to music (38) and listening to radio (37) with 2,784,900 subjects surveyed. On weekend, sports (37%) was ranked even lower at seventh, falling behind activities like shopping and dinning out.

Said Nanyang Technological University undergraduate Melody Tan: “ I know I should exercise but somehow when I comes to doing it, I just feel lazy and cannot find energy or the motivation”(Yi Shen, 2006). Singapore Sport Council high participation division director Michael Chan has set the target to at least 50 percent of Singaporean active by 2011, with more of them exercising three or more times per week; this is challenging goal. At present Scandinavian countries such as Finland, which have a big sporting culture, which have only 50 percent of the population participates in sport. In addition, there is a concern to corporations, government and individual to control the health care costs. The preventive approach to cut costs is to prevent health problems before there arise thus avoiding the treatment costs in the first place (Gettman, 2000).

Exercise in many cases is as effective as psychological effect as psychotherapy and antidepressant drugs in treating emotional disorders (Lawlor & Hopker, 2001). Epidemiological studies have shown an inverse related to depressive symptoms and that individuals who increased their activity over time were at no greater risk for depression than individuals who had been physically active all along (Babyak et al., 2000). Millions of people worldwide are affected by mental health and are associated to increased morbidity and healthcare costs (Fontaine, 2000).

This paper shall cover the topics on 1) the psychological benefits of exercise and 2) teachers, coaches and exercise leader/trainer to enhance the benefits.

Psychological Benefits

Many literatures support the position of regular exercise leads to improve in psychological affect. Improved affect manifested in the form of reduction in negative affect like anxiety and depression and increase the positive affect like self-efficacy, vigor and well-being.

We cannot say that “exercise improve health and physical well-being” without qualifying. In practical term, it would be wise to say fit by doing aerobics, walking, swimming, and jumping rope; and if we play football, rugby, hockey, or other competitive contact sports, we need to have good health insurances due to injuries (Coakley, 2007, p. 105).

It is generally believed that best psychological benefits are derived using a moderate intensity of exercise as opposed to a very low or a very high intensity, the evidence through well controlled investigation is researched by Cox R.H., Thomas T.R, Hinston P.S. and Donahue in 2004 (Cox, 2007, p. 393) that a bout of relatively intense exercise is superior to a moderate bout of aerobic exercise in terms of reducing state anxiety. This concludes Cox’s research, exercise of moderate and slight intense exercises are effective in reducing state anxiety. With sixty minutes of cross-training, or training that includes both acute (refers to exercise that is short duration, e.g. 30 minutes) aerobic exercise and resistance training (involves the use of weights or weight training for muscle strength training) has shown to be effective in reduce the anxiety (Hale, Koch, & Raglin, 2002).

Reductions in state anxiety are not necessarily observed immediately following exercise. Delay anxiolytic effect is the result in an anxiety decrease following a delay of 30 to 90 minutes after acute bout of aerobic or resistance training. This effect can be due to either the intensity of the exercise or the arousal component of the anxiety (Cox, Thomas, & Davis, 2000). Brain derived neurtorophic factor (BDNF) is the brain produced molecules that nourish neurons and ensure the overall brain health. This protein seems to act as a ringleader, both prompting brain benefits on its own and triggering a cascade of other neural health–promoting chemicals to spring into action. Cotman and Engesser done the research in 2002 (as cited in Cox, 2007, p. 394) shows that exercises increase the BDNF presence in the brain.

Craft & Landers done their research in 1998 (as cited in Daley, 2002): The effect of exercise on clinical depression and depression resulting from mental illnesses: Journal of Sports & Exercise Psychology, the benefits of regular physical activity are greater for individual suffering from psychological disorders than normal individuals. The research had shown increased in positive mood and self-efficacy for clinically depressed individuals participating in martial arts. The benefits include a) effective clinical depression reduction during aerobic and non-aerobic exercise, b) more depressed individual benefit from exercise, c) exercise was beneficial as psychotherapy and drug therapy for reduce depression and d) chronic exercise programs were more effective than acute exercise.

When elderly participate in aerobic exercise, the selective cognitive function is preserved and the rate of the decline is retarded which normally declines with age. In research on older adult of age between 60 to 70 participating in a six month program experimenting reduction in confusion, tension and anger (Cox, 2007, p. 396). Elderly must continue to exercise to enjoy the psychological benefits at an intensity that leads to perspiring and heavy breathing.

Social– cognitive theory is used to explain the effect of physical activity on well-being (Netz, Wu, Becker, & Tenenbaum, 2005). On the basis of a conceptual framework proposed for evaluating well-being in older age, four general components were considered: (a) emotional well-being (i.e., state and trait anxiety, stress, tension, state and trait depression, anger, confusion, energy, vigor, fatigue, positive affect, negative affect, and optimism), (b) self-perceptions (i.e., self-efficacy, self-worth, self-esteem, self- concept, body image, perceived physical fitness, sense of mastery, and locus of control), (c) bodily well-being (i.e., pain and perception of physical symptoms), and (d) global perceptions such as life-satisfaction and overall well-being. Aerobic training was most beneficial and moderate intensity activity was the most beneficial activity level. Longer exercise duration was less beneficial for several types of well-being, though findings are inconclusive. Physical activity had the strongest effects on self-efficacy, and improvements in cardiovascular status, strength, and functional capacity were linked to well-being improvement overall. With cardiovascular fitness, exercise stimulates the production of neurotransmitters, which has positive effect upon psychological mood states. Studies have shown that depressed individual often has reduction in the secretion of various amine such as norepinephrine, serotonin, and dopamine (Cox, 2007, p. 398).

Report of the Surgeon General: Physical Activity and Health Adolescents and Young Adults recommends that exercise serves and to have beneficial effect on psychological mood and physiological as for the children and adult. Without successful treatment on the negative mood states, depressed adolescents are at an elevated risk for academic failure, social isolation, promiscuity, drug and alcohol abuse, and suicide (Motl, Birnbaum, Kubik, & Dishman, 2004).
Exercise in social interaction such as with friends and colleagues is pleasure and has positive effect in improving the mental health; exercise along and at home results in greater reductions in negative mood than at other places (Landers, 1997). Exercise helps individual to distract from worry and frustration. Chronic exercise is more powerful and effective in reducing negative mood state than relaxation exercise.

Endorphin is the brain production of chemicals that have “morphine-like” effect on exerciser and sometimes call ”runner’s high” in sports science. The general euphoria produced by the endorphins serve to reduce the negative mood states (Cox, 2007, p. 400).

Exercises have significant effects on cellular expression of adhesion molecules on circulating leukocytes. Given the crucial role that adhesion molecules on circulating cells play in inflammation and disease, these findings may have clinical relevance in sympathetic nervous system–induced immune activation (Goebel & Mills, 2000) (Nieman, 2001) – this improves the immune system.

Teachers, coaches and exercise leader/trainer enhance benefits to participants

Children behaviour are greatly influenced by their parents’ attitude and behaviour regarding exercise (Sarah, Nancy, Mary, & Marsha, 2004, p. 131). Coaches and teachers are often like parents ensuring that the children are motivated for sport and exercise participation and are fun and enjoyment. They have more fun if they can enjoy some success. The benefits of sport or motives of participation (Cox, 2007, p. 131) and the reasons youth participate in sports 1) include having fun and to enjoy participating in sport, 2) to learn new skills and to improve existing sport skills, 3) to be physically fit and enjoy good health, 4) To enjoy the challenge and excitement of sports participation and competition and 5) to enjoy a team atmosphere and to be with friends. Other benefits include learning to cooperate, learning to be a good sport, gaining self-confidence and self esteem. Keeping kids motivated to participate in physical activities will also naturally lead to touted health outcomes (Weiss, 2000).

Burnout in sport exercise is a psychological syndrome of emotional/ physical exhaustion, reduced sense of accomplishment, and sport or exercise devaluation(Cox, 2007, p. 427). This reduced the mental exhaustion, reduced interest and reduced performance. Teachers, coaches and leaders can 1) cultivate personal involvement with people participate in exercise, 2) establish two-way communication, 3) solicit and utilize inputs and 4) work to understand her feelings and perspective. Per Coakley’s empowerment model of burnout (Coakley, 2007, p. 97), especially in youth sport, the coaches and the leader of the organization must develop a positive sporting experience so that there alternative identity and feel control over the her life.
Coaches’, teachers’ and leaders’ feedback and reinforcement comprise informational (i.e. Instruction) or evaluative (e.g. praise) responses to participation and performance. Quantity and quality of feedbacks to the participants result in positive outcome. They must engage in more frequent praise for desirable behaviour (effort & technique), encouragement following skill errors, and instructions following performance attempts were associated with players or participants who were higher in perceived ability, enjoyment, and intention to continue to playing, and lower in anxiety and attrition rates. The environment is structured to encourage self-referenced definition of success (e.g. improvement, mastery, enjoyment) rather than normative standards or peer comparison, are likely to influence participants’ self perceptions, emotion reactions, and motivation to continue activity involvement. Participants feel empowered that they determine their own behaviours, and this is positively tied to motivated behaviours.

Conclusion

Exercise encourages and generates positive thoughts and feelings that serves to counteract the negative mood states (depression, anxiety and confusion etc.) which is parallel with Bandura theory (Cox, 2007, p. 104) of self efficacy. When individual master tasks they perceived to be difficult, they experience an increase in self-efficacy. Non-exerciser (perceived exercise as difficult task) when succeeds to become a regular exercise, they experience a feeling of accomplishment and self-efficacy. An increase in self-efficacy helps to break up the negative affect of downward spiral link to depression, anxiety, confusion etc.; the negative mood state.

Children and adolescent stay active and are motivated, they may lead to active adolescent and adults. Specifically, significant adults are primed to structure the environment and exhibit behaviours that enhance children’s physical competency beliefs, self-esteem, and enjoyment of physical activity.

The psychological benefits of exercise are very important. Exercise decreases stress and relieve tensions that might otherwise lead to negative psychological effect and physique such as overeating. Exercise builds physical fitness which in turn builds self-confidence, enhanced self-image, and a positive outlook. When one starts to feel good about oneself, one is more likely to want to make other positive changes in lifestyle that will help keep weight under control. In addition, exercise is fun, it provides recreation and offer opportunities for companionship. The exhilaration and emotional release of participating in sports or other exercise activities are a boost to mental and physical health. Pent-up anxieties and frustrations seem to disappear when one is concentrating on returning a serve, sinking a putt or going for that extra mile.

Tai Chi Research Case Studies

Case Studies: looking at 3 interesting independent research on their hypothesis and conclusions.

1. The research done in Taiwan (Lan & Lai, 1993) had shown that Taichi (Yang style with 20min warm-up, 30 min practice & 10 min cool down) was beneficial to cardiorespiratory function. The HRmax and RER remain; and VO2max (measurement for aerobic performance) were higher.

2. The research done in United States (Tsao & Ratliff, 1982) had shown that it was unlikely that Taichi (Yang Style) effectively contributes to development of cardiovascular fitness in the traditional sense. The subjects were been measured on their VO2 during practise. The experienced practioners had higher the VO2.

3. Research in June 2007 (Takeshima et al., 2006) had shown that the functional fitness gain varies on older adults depending on exercise mode. It was hypothesised that to improve the function fitness, one type be aerobic exercise and the second type be chosen from Resistance, Balance and Taichi.

The 1993 research (about 47 +/- 9 yrs old) had shown that Taichi could improve aerobic capacity and hence the cardiorespiratory fitness. Research in United States was using younger adults (29.4 +/- 8.6 yrs old) had 55.7% of HRmax which lead to the conclusion that it was not sufficient for cardiorespiratory fitness unless the intensity was higher; this was almost similar observations on some Taichi groups here. Another interesting finding was that the more mastery the subject, the higher the VO2 which shown that the skills and techniques been able to master over the years. If the research in United States had done on subects with proper biomechanics and skill sets (that would contribute to moderate intensity) and to measure on the VO2max, the results would most likely to be similar.

Considering the physical preparation and practicing for example the Taichi 42 competition set or Chen style Taichi with proper biomechanics, one should be able to achieve functional fitness = aerobic exercise + Resistance OR Balance. Taichi practice can achieve the balance component, the strength endurance with wrist and ankle weight and strength component through resistance training from physical preparation (Refer to Taichi Physical Fitness on 14th Oct '08).


Some other concern on the training programs :

1. Right Taichi training method (right skills set and biomechanics) so the motor programs (neuro & muscular) and learning are correct from the start before habitualisation. Interval training allows the exercise intensity to vary according to the program. Slowing down with fine motor movement (心静体松, 呼吸自然, 轻灵沉着, 圆活连贯, 上下相随, 虚实分明, 柔中寓刚, 以意导动) in the program create balance (coherence) between the parasympathetic and sympathetic nerves system.

2. Symmetrical training for postural muscle balance (single sword training --> dominant hand will have shorter muscles than the other) causing postural muscle fatigue (abnormal muscle force compensation) at rest

3. Program design must able to increase bone strength (Turner & Robling, 2003)

4. Training (maintenance) that is on-going to bring both health and fitness level to later part of life cycle etc.

Qigong May Lower Hypertension BUT did not prove more beneficial than conventional exercise

Practice of the ancient Chinese art of qigong may offer relief to people with high blood pressure, according to a paper published (from Guangzhou University of Traditional Chinese Medicine) in The Journal of Alternative and Complimentary Medicine (Guo, Zhou, Nishimura, Teramukai, & Fukushima, 2008 ). Scientists review 92 studies but found only nine that qualified for meta-analysis. Among these studies, people who consistently practiced qigong experienced a greater drop in blood pressure than those who received no treatment of any kind. However qigong did not prove more beneficial than conventional exercise.

From psychological point, the mind relaxation enable this postive effect but scientifically may not able to achieve the full health and fitness requirements. Refer to 14th Oct article on the Taichi Physical Fitness

Definitions of Sedentary behavior and light physical activity

Sedentary behaviour refers to activities that do not increase energy expenditure substantially above the resting level and includes activities such as sleeping, sitting, lying down, and watching television, and other forms of screen-based entertainment. Operationally, sedentary behavior includes activities that involve energy expenditure at the level of 1.0 - 1.5 metabolic equivalent units (METs). (One MET is the energy cost of resting quietly, often defined in terms of oxygen uptake as 3.5 mL/kg/min).

Light physical activity, which often is grouped with sedentary behaviour but is in fact a distinct activity construct, involves energy expenditure at the level of 1.6 - 2.9 METs. It includes activities such as slow walking, sitting and writing, cooking food, and washing dishes.


Men who expended less than an estimated 2000 kcal per week (taking 5 exercise days per week, the estimated energy expenditure is 400kcal per day) through walking, climbing stairs, and playing sports were classified as sedentary. The sedentary men had a 31% higher risk of death than more active men (Paffenbarger, Hyde, Wing, & Hsieh, 1986).

Beginning with moderately vigorous (intensity) sports activity, quitting cigarette smoking, maintaining normal blood pressure, and avoiding obesity were separately associated with lower rates of death from all causes and from coronary heart disease among middle-aged and older men (Paffenbarger et al., 1993).

Hence, in our Taichi practices, we have to perform to the moderate intensity at minimum such as through lowering our stance with correct biomechanics, wrist and ankle weight, eccentric movement on lower and upper extremities (myofascial sling) etc. Interval practices by combining the various style such as Yang style for slow and kinesthetic movement and Chen style for fast propulsive movement to meet all the physical fitness requirement.

Physical preparation through periodization is important for training the flexibility, strength, agility, endurance etc.; this set up the base fitness to perform Taichi movement.

2008 The Physical Activity Guidelines for Americans


On 7th October, The U.S. Department of Health and Human Services (HHS) guidelines state adults should exercise for two and a half hours - or 150 minutes - per week at a moderate intensity. This breaks down into 30 minutes of exercise five days per week, consistent with guidelines released last August by ACSM and the American Heart Association. Read more about the federal guidelines at http://www.health.gov/PAGuidelines/. Some snapshot summary extract from the "At-A-Glance: A Fact Sheet for Professionals" article.


Children and Adolescents (aged 6–17)
• Children and adolescents should do 1 hour (60 minutes) or more of physical activity every day.
• Most of the 1 hour or more a day should be either moderate- or vigorous-intensity aerobic physical activity.
• As part of their daily physical activity, children and adolescents should do vigorous-intensity activity on at least 3 days per week. They also should do muscle-strengthening and bone-strengthening activity on at least 3 days per week.


Adults (aged 18–64)
• Adults should do 2 hours and 30 minutes a week of moderate-intensity, or 1 hour and 15 minutes (75 minutes) a week of vigorous-intensity aerobic physical activity, or an equivalent combination of moderate- and vigorous-intensity aerobic physical activity. Aerobic activity should be performed in episodes of at least 10 minutes, preferably spread throughout the week.
• Additional health benefits are provided by increasing to 5 hours (300 minutes) a week of moderate-intensity aerobic physical activity, or 2 hours and 30 minutes a week of vigorous-intensity physical activity, or an equivalent combination of both.
• Adults should also do muscle-strengthening activities that involve all major muscle groups performed on 2 or more days per week.


Older Adults (aged 65 and older)
• Older adults should follow the adult guidelines. If this is not possible due to limiting chronic conditions, older adults should be as physically active as their abilities allow. They should avoid inactivity. Older adults should do exercises that maintain or improve balance if they are at risk of falling.
For all individuals, some activity is better than none. Physical activity is safe for almost everyone, and the health benefits of physical activity far outweigh the risks. People without diagnosed chronic conditions (such as diabetes, heart disease, or osteoarthritis) and who do not have symptoms (e.g., chest pain or pressure, dizziness, or joint pain) do not need to consult with a health care provider about physical activity.

Incorporating all the health and fitness components (Oct '08 articles) into exercise programs may not be easy for busy working adults, executives, businessmen and women when time is hard to optmise. The amount of time spend on exercises whether it is physical preparation and conditioning or routine practices must be effective and meeting the health and fitness requirements.

This requires a proper exercise prescriptions (daily and weekly) for individuals and appropriate circuit design (including bad weather) using existing natural environment (depending on individual preferences, preferably mixture of indoor and outdoor) around us to keep us healthy and fit. Time must be well-spend.

For example: some of my clients are doing warming up and stretching at home, their Taichi aerobic activties are done using the outdoor circuit and cooling down with Taichi routines followed by stretching near thereby their house. The re-hydration with fuild is done at home during rest followed by his bath. They have multiple version of programs (changing the variables of the components and types) for variety.
