Training and Detraining Effects of the Resistance vs. Endurance Program on Body Composition, Body Size, and Physical Performance in Young Men

Abstract

The purpose of this study was to investigate the changes in the body composition, body size, muscle strength, and VO2max 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. VO2max, 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 VO2max 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<0.05). In addition, the strength and LM of the RTG were still greater than the baseline values after 24 weeks of detraining (p < 0.05). The conclusions of this study are (a) that endurance or resistance training alone led to training-specific improvements in physical performance, body composition, and body size of the arms for the young men examined and (b) that the RTG maintained the gains in strength and LM for more prolonged periods after training ceased than the endurance training group.

Concurrent Training Followed by Detraining: Does the Resistance Training Intensity Matter?

“…The detraining adaptations following strength or endurance training alone have been widely studied in different populations (8,9,26,31,36) Unfortunately, the effect of training cessation after CT has received less scientific attention (4,45,46,49). Moreover, although abrupt cessation of intense physical training is associated with a decline of physical performance (38-40), detraininginduced changes in performance after concurrent training are linked with multiple factors A C C E P T E D (16,31,36,46,49,50) among which is included the relative intensity used during previous resistance program. Therefore, the second aim of the present study was to analyze the effects of 4-week DT following concurrent training programs differing in load magnitude used during resistance training on different strength and aerobic parameters.…”

Examination the Effects of Aerobic and Resistance Exercise on Body Compositions of Sedentary Male Individuals

“…Conversely, endurance training significantly changes body composition and promotes metabolic adaptations and maximum oxygen uptake, which leads to an increase in the training capacity. Although endurance training generally does not cause a significant muscle mass increase, it can be more effective than anaerobic resistance training in increasing maximal oxygen consumption (Lo, Lin, Yao & Ma, 2011). Toraman et al (2002) examined the effects of a 9-week training program on body composition in the elderly.…”

Muscular glucose metabolism in middle-age trained rats

“…Lo et al demonstrated that individuals who trained aerobically for a period of time and were subsequently maintained for 24 weeks without training (i.e., ''detrained'') lost the achieved adjustments with training and exhibited an increase in body weight and reductions in VO 2max [40]. Other studies [29,[41][42][43][44][45] have argued that detraining produced losses in aerobic capacity, altered body composition and decreased basal metabolism.…”
