Lo, MS, Lin, LLC, Yao, W-J, and Ma, M-C. Training and detraining effects of the resistance vs. endurance program on body composition, body size, and physical performance in young men. J Strength Cond Res 25(8)2246-2254, 2011—The purpose of this study was to investigate the changes in the body composition, body size, muscle strength, and O2max after 24 weeks of resistance or endurance training and detraining in young men. Thirty healthy college-aged men (20.4 ± 1.36 years) participated in the study. Subjects were assigned to resistance training group (RTG, n = 10), endurance training group (ETG, n = 10), and control group (CG, n = 10). The training program consisted of running or weight-resistance exercise for 3 sessions per week under supervision. O2max, upper and lower body strength (UBS, LBS), body fat, lean body mass, and body circumference were measured at baseline and after training and detraining. After the training period, the exercise groups demonstrated significant increases in O2max and LBS (p < 0.05). The UBS, lean mass (LM), and body size of arm and calf were significantly greater in the RTG than in the other 2 groups (p
