AB  - Colquhoun, RJ, Gai, CM, Aguilar, D, Bove, D, Dolan, J, Vargas, A, Couvillion, K, 
      Jenkins, NDM, and Campbell, BI. Training volume, not frequency, indicative of 
      maximal strength adaptations to resistance training. J Strength Cond Res 32(5): 
      1207-1213, 2018-To compare the effects of a high versus a moderate training 
      frequency on maximal strength and body composition. Twenty-eight young, healthy 
      resistance-trained men were randomly assigned to either: 3x per week (3x; n = 16) 
      or 6x per week (6x; n = 12). Dependent variables (DVs) assessed at baseline and 
      after the 6-week training intervention included: squat 1 repetition maximum 
      (SQ1RM), bench press 1RM (BP1RM), deadlift 1RM (DL1RM), powerlifting total (PLT), 
      Wilk's coefficient (WC), fat-free mass (FFM), and fat mass. Data for each DV were 
      analyzed using a 2 x 2 between-within factorial repeated-measures analysis of 
      variance. There was a main effect for time (p < 0.001) for SQ1RM (3x: +16.8 kg; 
      6x: +16.7 kg), BP1RM (3x: +7.8 kg; 6x: +8.8 kg), DL1RM (3x: +19 kg; 6x: +21 kg), 
      PLT (3x: +43.6 kg; 6x: +46.5 kg), WC (3x: +27; 6x: +27.1), and FFM (3x: +1.7 kg; 
      6x: +2.6 kg). There were no group x time interactions or main effects for group. 
      The primary finding was that 6 weeks of resistance training led to significant 
      increases in maximal strength and FFM. In addition, it seems that increased 
      training frequency does not lead to additional strength improvements when volume 
      and intensity are equated. High-frequency (6x per week) resistance training does 
      not seem to offer additional strength and hypertrophy benefits over lower 
      frequency (3x per week) when volume and intensity are equated. Coaches and 
      practitioners can therefore expect similar increases in strength and lean body 
      mass with both 3 and 6 weekly sessions.
