BACKGROUND It is of a public health interest to explore the relationship between different types of physical activity, sleep duration and diabetes/insulin resistance. However, little is known about such relationship. This study examines the single and joint associations of different types of physical activity, and sleep duration on insulin resistance among non-diabetic Chinese adults. METHODS...

Twenty-five randomly selected, low or moderately fit and healthy women (22-44 years) rated their perceived physical capacity and performed an incremental cycle exercise test with respiratory gas analysis. The aerobic and functional capacity did not decrease with age. However, tauVo(2) increased with age. The mean value of the perceived physical capacity was 10 metabolic equivalents and that of ...

OBJECTIVES To describe the objectively measured physical activity characteristics of a diverse sample of sixth-grade girls, to examine influences on physical activity, and to report compliance with physical activity guidelines. DESIGN Cross-sectional study. SETTING Six locations across the United States. PARTICIPANTS A total of 1578 sixth-grade girls. Accelerometers were worn for 7 days, ...

BACKGROUND Higher physical activity (PA) levels are known to be associated with lower risk of death. Less attention, however, has been paid to directly evaluate the effect of PA on the time by which a certain fraction of the population has died. METHODS A population-based cohort of 29,362 men 45 to 79 years of age was followed from January 1998 to December 2010. A total of 4,570 men died. PA ...

Many studies documented the relationship between elevated plasma concentrations of natriuretic peptides and cardiovascular diseases, especially heart failure. However, it is still uncertain whether physical exercise leads to a significant release of natriuretic peptide in healthy subjects. The aim of this study was to determine the effect of maximal physical activity on plasma BNP concentration...

BACKGROUND Retirement is a major life transition which may affect lifestyle. The aim of this study is to examine within-individual changes in physical activity during the transition from full-time work to retirement. METHODS The study population consisted of 9,488 Finnish public-sector employees who retired in 2000-2011 and who reported their leisure-time and commuting physical activity befor...

Background: Instructions for older adults regarding the intensity of walking may not elicit an intensity to infer health gains. We recorded the metabolic equivalents (METs) during a 1-mile walk using constant and predicted values of resting MET in older adults to establish walking guidelines for health promotion and participation. Methods: In a cross-sectional design study, participants (15 men...

Abstract Objectives Lawn tennis is an explosive sport that involves various fitness parameters such as strength, endurance, power, and agility. Improved physical leads to superior athletic performance. The coach's perception contingent upon his of the player at time athlete comparing himself coach. Thus, this study aimed determine association between chosen factors perceived performance by coac...

OBJECTIVE To assess the association between exercise capacity and the risk of developing atrial fibrillation (AF). PATIENTS AND METHODS A symptom-limited exercise tolerance test was conducted to assess exercise capacity in 5962 veterans (mean age, 56.8±11.0 years) from the Veterans Affairs Medical Center, Washington, DC. None had evidence of AF or ischemia at the time of or before undergoing ...
