Abstract The effects of a 4-week training program on changes in body girth, subcutaneous tissue, muscular strength and endurance, and cardiovascular fitness of physically conditioned young men were investigated. Seventeen members of a karate class from the University of Minnesota were randomly assigned to an experimental group (N = 11) and a control group (N = 6).
