Abstract
Abstract Thirty-four healthy but inactive young men were subjected to measures of: gross body weight, relative body weight, height, percent body fat, fat-free body weight, and the Balke test of treadmill performance. A multiple regression analysis of the data indicated that 52.21 percent of the total interpersonal variance in treadmill performance time of the inactive group under study was accounted for by the five anthropometrical variables. Body fat (38.87 percent), fat-free body weight (9.72 percent), and relative body weight (1.72 percent) each accounted for a significant portion of the total variance. A decline in these relationships observed with seven subjects undergoing training indicated that treadmill performance time had improved somewhat independently of changes in body composition or body mass. The interdependence of anatomical and physiological variables as determinants of submaximal cardiovascular performance was discussed.
