Abstract
A small group of obese and non-obese young men were subjected to 18 consecutive weeks of: daily training (eight weeks), normal activity (five weeks), and daily training (five weeks). Selected aspects of body composition were appraised through measurements of body density, subcutaneous tissue, and “fat-corrected” limb circumferences. Initially overweight subjects experienced significant losses of body weight, and subcutaneous and total body fat, and increases in fat-free body weight and muscular mass. Neither fat nor weight loss was dependent upon the initial degree of obesity. Gains in fat-free weight, however, showed some relation to the amount of excess fat being carried. One very thin subject experienced a substantial weight gain which was almost entirely composed of nonfatty tissue.
