The relationship between leg strength and movement time for women: with body composition factors held constant

This study was designed to examine the relationship between movement time and leg strength with body composition factors held constant. Two research hypotheses were tested. The first research hypothesis was: with body composition factors held constant, force will be related to acceleration. The second research hypothesis was: with body composition factors held constant, force and velocity will be independent. The subjects were 36 adult female volunteers. The dependent variables were three measures of movement time at the following distances: 0 to 20 feet, 20 to 40 feet, and 40 to 60 feet. There were five independent variables. Body composition was composed of four factors: subcutaneous body fat, lean body weight measuring muscle mass and bone structure, lean body weight measuring bone diameters, and fat specific to the pelvic girdle. The other independent variable was leg strength measured by the leg press on the Cybex. [...]
