the aim of this study was to investigate the effect of endurance, resistance and concurrent training on plasma leptin levels of male students. for this purpose, 48 male university students (mean age 21.45 years) participated in this study. subjects were randomly assigned to three exercise groups: endurance group (n=12), resistance group (n=12) and concurrent group (n=12) and a control group (n=...

The purpose of this study was to evaluate the effects of a circuit training program along with a maintenance program on muscular and cardiovascular endurance in children in a physical education setting. Seventy two children 10-12 years old from four different classes were randomly grouped into either an experimental group (n = 35) or a control group (n = 37) (two classes for each group). After ...

[Purpose] We investigated the physical condition of middle-aged workers in Korea by job category (office job vs. production job). [Subjects] In total, 3,650 middle-aged workers (production job, n = 2,615; office job, n = 1,035) ≥50 years of age from eight geographical areas were evaluated from 2007 to 2008. [Methods] The subjects' subjective physical condition, exercise status, smoking status, ...

OBJECTIVES To investigate the associations between natural selection to sports at a young age, continuity of physical activity, and occurrence of coronary heart disease. DESIGN Prospective cohort study. SETTING Finland. PARTICIPANTS Former top level male athletes participating at a young age (1920-1965) in different types of sport (endurance (n = 166), power speed (n = 235), "other" (n = ...

UNLABELLED Regular running and strength training are the best ways to improve aerobic capacity and develop the size of skeletal muscles. However, uncontrolled physical activities can often lead to an undertraining or over-training syndrome. In particular, overtraining causes persistent fatigue and reduces physical performance due to changes in the various physiological and immunological factors...

OBJECTIVES This randomized controlled trial studied the effects of a low- to moderate-intensity group exercise program on strength, endurance, mobility, and fall rates in fall-prone elderly men with chronic impairments. METHODS Fifty-nine community-living men (mean age = 74 years) with specific fall risk factors (i.e., leg weakness, impaired gait or balance, previous falls) were randomly assi...

BACKGROUND Gaelic football, soccer, and hurling are prominent field games in Ireland and involve participants undertaking a variety of playing tasks and skills which place various physiological demands on the participants. The aim of this study was to evaluate and compare the mid-season physiological profiles of elite players. METHODS Physiological assessment was carried out on 29 inter-count...

In humans, the ratio of the second digit to the fourth digit — the 2D:4D ratio — is a sexually dimorphic trait (men, on average, exhibit lower 2D:4D ratios than do women) that is influenced by prenatal testosterone exposure, but not by circulating testosterone levels in adulthood. Consequently, 2D:4D ratios are commonly used as indirect measures of prenatal testosterone exposure. Many studies h...
