Comparison of changes in lean body mass with a strength- versus muscle endurance-based resistance training program. Academic Article uri icon

abstract

  • PURPOSE: The aim of this study was to compare the effects of resistance training (RT) with an emphasis on either muscular strength-type RT or muscular endurance-type RT on measures of body composition. METHODS: Twenty-five resistance-trained men (age 28.46.4 years; body mass 75.98.4kg; height 176.97.5cm) were randomly assigned to either a strength-type RT group that performed three sets of 6-8 repetition maximum (RM) with 3-min rest (n=10), an endurance-type RT group that performed three sets of 20-25 RM with a 60-s rest interval (n=10), or a control group (n=5, CG). All groups completed each set until muscular failure and were supervised to follow a hyperenergetic diet (39 kcalkg-1day-1). Body composition changes were measured by dual-energy X-ray absorptiometry. RESULTS: After 8 weeks, we found significant increases in total body mass (0.9 [0.3-1.5] kg; p<0.05; ES=<0.2) and lean body mass (LBM) (1.3 [0.5-2.2] kg; p<0.05; ES=0.31) only in the strength-type RT group; however, no significant interactions were noted between groups. CONCLUSIONS: Although only strength-type RT showed statistically significant increases in LBM from baseline, no between-group differences were noted for any body composition outcome. These findings suggest that LBM gains in resistance trained are not significantly influenced by the type of training stimulus over an 8-week training period.
