Components Of A Basic Exercise Program
Even small changes boost couch potatoes' health " … any increase in physical activity is beneficial."
Exercise in youth has lasting bone benefits " Men who participate in athletics in their late teens experience bone-building benefits that last for years, even if they are no longer training intensively, a new study shows."
Exercise withdrawal causes mood change within days "People who exercise regularly start feeling depressed and fatigued after just one week of forced inactivity, a new study shows."
Exercise: The Antidote for a High-Fat Meal "So, you've just polished off a meal high in fat, and now you're feeling guilty? Wait an hour or two, then get a little exercise, and you can reverse the potential damage to your arteries, a new study suggests. And you don't even have to head to the gym for that exercise. "We're talking about a walk, we're not talking about changing your clothes and sweating," said Janet P. Wallace, a professor of kinesiology at Indiana University, and lead investigator for the study."
Experts Offer Tips to Healthy Exercise
Get Intense for Greater Exercise Benefit "It is possible to get more out of each step and reach a higher level of fitness. Just pump up your next walk by walking faster and finding a route that has you walking uphill."
High-Intensity Physical Activity Reduces Cardiovascular Risk in Children
Moderate Exercise May Improve Cardiovascular Risk Factors, Life Expectancy "A prescription for walking either at hard intensity (HardI) or at high frequency (HiF) can improve cardiovascular risk factors … A second analysis, based on Framingham study data, suggests that life expectancy can be improved by moderate- and high-intensity exercise by those older than 50 years."
Physical Fitness Contributes to Successful Mental Aging "Physical fitness, as defined by a latent trait consisting of 3 tests, is associated with healthy cognitive aging."
Starting Exercise Means a Medical 'Tune-Up' First
Urban Exercise Has Its Hazards " . the danger lies in the components of air pollution. The three main culprits are fine particulate matter, (the mixture of solid particles and liquid droplets in the air), ozone (a gas composed of three oxygen atoms) and carbon monoxide."

Why Physical Activity And Exercise Are Important
JOURNAL ARTICLES:
Aerobic exercise and HDL2-C: A meta-analysis of randomized controlled trials (Atherosclerosis 2006)
Aerobic exercise training increases skeletal muscle protein turnover in healthy adults at rest. (J Nutr. 2006)
Aerobic exercise, but not flexibility/resistance exercise, reduces serum IL-18, CRP, and IL-6 independent of ß-blockers, BMI, and psychosocial factors in older adults (Brain, Behavior, and Immunity 2006) "Increased serum levels of inflammatory mediators have been associated with numerous disease states including atherosclerosis, Type II diabetes, hypertension, depression, and overall mortality. We hypothesized that a long-term exercise intervention among older adults would reduce serum inflammatory cytokines, and this reduction would be mediated, in part, by improvements in psychosocial factors and/or by ß-adrenergic receptor mechanisms. . In summary, we have observed that an aerobic exercise intervention can significantly reduce serum inflammatory mediators, but ß-adrenergic receptors and psychosocial factors do not appear to be involved."
Amount and Intensity of Physical Activity, Fitness, and Serum Lipids in Pre-Menopausal Women (Int J Sports Med 2006)
Blood pressure rise with swimming versus walking in older women: the Sedentary Women Exercise Adherence Trial 2 (SWEAT 2). (Journal of Hypertension 2006) "Conclusion: Relative to moderately paced walking, regular swimming significantly elevates BP in previously sedentary, normotensive, older women. This finding may have important implications for exercise prescription in older subjects." /p>
Cardiocirculatory and metabolic responses at different walking intensities. (Br J Sports Med. 2006)
Child-Adult Differences in the Recovery From High-Intensity Exercise (Exerc Sport Sci Rev. 2006)
Comparison of cardioprotective benefits of vigorous versus moderate intensity aerobic exercise. (Am J Cardiol. 2006)
Depressive mood symptoms and fatigue after exercise withdrawal: the potential role of decreased fitness. (Psychosom Med. 2006) "CONCLUSION: Depressed mood and fatigue are commonly observed in individuals deprived of usual exercise activities, and the increase in fatigue may be partially mediated by reduced fitness levels. These findings may explain mood changes in response to short-term exercise withdrawal such as injuries and recovery from medical procedures that do not require full bedrest."
Does the intensity of an exercise programme modulate body composition changes? (Int J Sports Med. 2006) "In conclusion, exercise training at 45 % of V.O (2max) without dietary restriction produced a higher weight loss than at 72 % of V.O (2max), whereas the higher intensity tended to maintain fat-free mass, possibly, in part, through the smaller weight loss. Thus, both programmes may prove useful in eliciting favourable changes depending on which target (weight loss or maintenance of fat-free mass) is of higher priority."
Effects of exercise frequency on functional fitness in older adult women. (Arch Gerontol Geriatr. 2006) "Older women who participate in an exercise program three times a week gain greater functional fitness benefits than those who exercise less frequently. In order to improve functional fitness in older women, an exercise frequency of at least three times each week should be recommended."

Exercise When Young Provides Lifelong Benefits to Bone Structure and Strength. (J Bone Miner Res. 2006)
Exercise, hypoalgesia and blood pressure. (Sports Med. 2006) "A number of studies have indicated that exercise is associated with alterations in pain perception. In general, investigators have typically found a hypoalgesic response (i.e. diminished pain perception) to occur during and following exercise. . "
Functional and structural vascular remodeling in elite rowers assessed by cardiovascular magnetic resonance. (J Am Coll Cardiol. 2006)
Health benefits of physical activity: the evidence (CMAJ 2006) "We confirm that there is irrefutable evidence of the effectiveness of regular physical activity in the primary and secondary prevention of several chronic diseases (e.g., cardiovascular disease, diabetes, cancer, hypertension, obesity, depression and osteoporosis) and premature death. We also reveal that the current Health Canada physical activity guidelines are sufficient to elicit health benefits, especially in previously sedentary people. There appears to be a linear relation between physical activity and health status, such that a further increase in physical activity and fitness will lead to additional improvements in health status."

Moderate Exercise: No Pain, Big Gains (Medscape Internal Medicine. 2006)
Moderate-Intensity Exercise Reduces the Incidence of Colds Among Postmenopausal Women (The American Journal of Medicine 2006) "This study suggests that 1 year of moderate-intensity exercise training can reduce the incidence of colds among postmenopausal women. These findings are of public health relevance and add a new facet to the growing literature on the health benefits of moderate exercise."

Regular physical activity reduces hospital admission and mortality in chronic obstructive pulmonary disease: a population based cohort study (Thorax 2006) "Conclusions: Subjects with COPD who perform some level of regular physical activity have a lower risk of both COPD admissions and mortality. The recommendation that COPD patients be encouraged to maintain or increase their levels of regular physical activity should be considered in future COPD guidelines, since it is likely to result in a relevant public health benefit."
Site-specific response of bone to exercise in premenopausal women. (Bone. 2006) "Our data support the site-specific response of spine and hip bone density to upper and lower body exercise training, respectively. These data could contribute to a site-specific exercise prescription for bone health."
