Schoenfeld, BJ, Ratamess, NA, Peterson, MD, Contreras, B, and Tiryaki-Sonmez, G. Influence of resistance training frequency on muscular adaptations in well-trained men. J Strength Cond Res 29 (7): 1821–1829, 2015—The purpose of this study was to investigate the effects of training muscle groups 1 day per week using a split-body routine (SPLIT) vs. 3 days per week using a total-body routine (TOTAL) on muscular adaptations in well-trained men. Subjects were 20 male volunteers (height= 1.76±0.05 m; body mass= 78.0±10.7 kg; age= 23.5±2.9 years) recruited from a university population. Participants were pair matched according to baseline strength and then randomly assigned to 1 of the 2 experimental groups: a SPLIT, where multiple exercises were performed for a specific muscle group in a session with 2–3 muscle groups trained per session (n= 10) or a TOTAL, where 1 exercise was performed per …
