Steven C Moore, I-Min Lee, Elisabete Weiderpass, Peter T Campbell, Joshua N Sampson, Cari M Kitahara, Sarah K Keadle, Hannah Arem, Amy Berrington de Gonzalez, Patricia Hartge, Hans-Olov Adami, Cindy K Blair, Kristin B Borch, Eric Boyd, David P Check, Agnès Fournier, Neal D Freedman, Marc Gunter, Mattias Johannson, Kay-Tee Khaw, Martha S Linet, Nicola Orsini, Yikyung Park, Elio Riboli, Kim Robien, Catherine Schairer, Howard Sesso, Michael Spriggs, Roy Van Dusen, Alicja Wolk, Charles E Matthews, Alpa V Patel
IMPORTANCE: Leisure-time physical activity has been associated with lower risk of heart-disease and all-cause mortality, but its association with risk of cancer is not well understood. OBJECTIVE: To determine the association of leisure-time physical activity with incidence of common types of cancer and whether associations vary by body size and/or smoking. DESIGN, SETTING, AND PARTICIPANTS: We pooled data from 12 prospective US and European cohorts with self-reported physical activity (baseline, 1987-2004)...

The main purpose of this study was the identification of the current pedometer determined physical activity levels of a large sample of 9 -14 years old Greek schoolchildren and the determination of the association between daily step counts and body mass index through the comparison of step counts among overweight, obese and normal-weight children. A total of 532 children (263 boys and 269 girls) were measured for height and weight. Their activity levels were analyzed using pedometers to measure mean steps for 7 consecutive days...

Hypertension (HTN), one of the most common medical disorders, is associated with an increased incidence of all-cause and cardiovascular disease (CVD) mortality. Lifestyle modifications are advocated for the prevention, treatment, and control of HTN, with exercise being an integral component. Exercise programs that primarily involve endurance activities prevent the development of HTN and lower blood pressure (BP) in adults with normal BP and those with HTN. The BP lowering effects of exercise are most pronounced in people with HTN who engage in endurance exercise with BP decreasing approximately 5-7 mm HG after an isolated exercise session (acute) or following exercise training (chronic)...

Purpose . Research demonstrates that moderate-to-vigorous physical activity (MVPA) is associated with a reduced risk of all-cause mortality. Few studies have examined the effects of light-intensity physical activity on mortality. Therefore, the purpose of this study was to examine the association between objectively measured light-intensity physical activity and all-cause mortality risk. Design . Longitudinal. Setting . National Health and Nutrition Examination Survey 2003-2006 with follow-up through December 31, 2011...

RANDOMIZED CONTROLLED TRIAL
Ina Garthe, Truls Raastad, Per Egil Refsnes, Jorunn Sundgot-Borgen
Strength training and positive energy intake are the most important factors related to lean body mass (LBM) gain. Most studies investigating weight-gain interventions are based recreationally active subjects and less is known about optimal weight-gain protocols in elite athletes. The purpose of this study was to evaluate the effect of nutritional guidance in an 8- to 12-week weight-gain period in elite athletes. Thirty-nine elite athletes were randomised to either a 'nutritional counseling group' (NCG, n=21, 19...

REVIEW

Exercise is a potent physiological stimulus for growth hormone (GH) secretion, and both aerobic and resistance exercise result in significant, acute increases in GH secretion. Contrary to previous suggestions that exercise-induced GH release requires that a "threshold" intensity be attained, recent research from our laboratory has shown that regardless of age or gender, there is a linear relationship between the magnitude of the acute increase in GH release and exercise intensity. The magnitude of GH release is greater in young women than in young men and is reduced by 4-7-fold in older individuals compared with younger individuals...

Human growth hormone (hGH) is secreted in a pulsatile fashion, generally following a circadian rhythm. A number of physiological stimuli can initiate hGH secretion, the most powerful, non-pharmacological of which are sleep and exercise. hGH has many varied roles throughout life, from growth itself, including the turnover of muscle, bone and collagen, to the regulation of selective aspects of metabolic function including increased fat metabolism and the maintenance of a healthier body composition in later life...

BACKGROUND: During nocturnal sleep, blood pressure (BP) "dips" compared to diurnal BP, reducing stress on the cardiovascular system. Both the hypotensive response elicited by acute aerobic exercise and sleep quality can impact this dipping response. PURPOSE: The purpose of this study was to investigate the effects of aerobic exercise timing on circadian BP changes and sleep architecture. MATERIALS AND METHODS: Twenty prehypertensive subjects completed the study...

REVIEW
Bernard C K Choi, Anita W P Pak, Jerome C L Choi, Elaine C L Choi
BACKGROUND: This review looks at ways to increase physical activity, by walking and other sports and home activities, to reach the daily 10,000 steps goal. It also looks at a number of issues associated with achieving the daily step goal, such as considerations in walking, step counting and physical activity. METHODS: The review is based on MEDLINE (1982-2006) and Google searches using keywords "pedometer", "daily step goal", "physical activity", "exercise". RESULTS: Research has suggested a daily 10,000 step goal for maintaining a desirable level of physical activity for health...

#10
REVIEW
Catrine Tudor-Locke, David R Bassett
Pedometers are simple and inexpensive body-worn motion sensors that are readily being used by researchers and practitioners to assess and motivate physical activity behaviours. Pedometer-determined physical activity indices are needed to guide their efforts. Therefore, the purpose of this article is to review the rationale and evidence for general pedometer-based indices for research and practice purposes. Specifically, we evaluate popular recommendations for steps/day and attempt to translate existing physical activity guidelines into steps/day equivalents...

The omega-3 fatty acid docosahexaenoic acid (DHA) has anti-inflammatory and anti-nociceptive (pain inhibiting) effects. Because strenuous exercise often results in local inflammation and pain, we hypothesized that DHA supplementation attenuates the rise in markers of local muscle inflammation and delayed onset muscle soreness (DOMS) that occur after eccentric strength exercise. Twenty-seven, healthy women (33 ± 2 y, BMI 23.1±1.0 kg·m(-2)) were randomized to receive 9d of 3000 mg/d DHA or placebo in a double-blind fashion...

Converging evidence demonstrates that physical activity evokes a brain state characterized by distinctive changes in brain metabolism and cortical function. Human studies have shown that physical activity leads to a generalized increase in electroencephalography power across regions and frequencies, and a global increase in brain nonoxidative metabolism of carbohydrate substrates. This nonoxidative consumption of carbohydrate has been hypothesized to include increased de novo synthesis of amino acid neurotransmitters, especially glutamate and GABA...
