background chronological aging is associated with a decrease in physical activity levels and consequently a decline in physical fitness, which may contribute to adverse conditions such as cardiovascular disease, hypertension, obesity and physical impairment. objectives this study sought to examine the effects of an 8-week physical activity intervention program on nutritional status and health-r...

The aim of this study was to investigate the factor structure of a Spanish version of the Sport Motivation Scale adapted to physical education. A second aim was to test which one of three hypothesized models (three, five and seven-factor) provided best model fit. 758 Spanish high school students completed the Sport Motivation Scale adapted for Physical Education and also completed the Learning ...

We introduce a new parameter to discuss the behavior of a genetic algorithm. This parameter is the mean number of exact copies of the best fit chromosomes from one generation to the next. We argue that the genetic algorithm should operate efficiently when this parameter is slightly larger than 1. We consider the case of the simple genetic algorithm with the roulette–wheel selection mechanism. W...

background : adiposity is correlated with metabolic complications, such as insulin resistance, glucose intolerance, hypertension etc. that finally can lead to coronary heart disease (chd). physical activity plays an important role in prevention of these diseases. we aimed to study body fat and plasma lipids and lipoproteins in different levels of physical fitness; also to examine any relationsh...

BACKGROUND Low levels of energy expenditure and aerobic fitness have been hypothesized to be risk factors for obesity. Longitudinal studies to determine whether energy expenditure influences weight gain in whites have provided conflicting results. To date, no studies have examined this relationship in blacks or whether aerobic fitness influences weight gain in white or black children. METHODS...
