All groups completed each set until muscular failure and were supervised to follow a hyperenergetic diet (39 kcal·kg−1·day−1). Body composition changes were measured by dual-energy X-ray absorptiometry.ResultsAfter 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.ConclusionsAlthough 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.
