Description

Purpose: To investigate the effect of different resistance training (RT) protocols with 5 equated volume load on acute mechanical and metabolic responses. Methods: In a 6 randomized order, eighteen men performed 8 different training protocols in the bench 7 press exercise consisting of (sets, repetitions, intensity, and inter-set recoveries): 3x16, 8 40% 1RM, 2 and 5 minutes; 6x8, 40% 1RM, 2 and 5 minutes; 3x8, 80% 1RM, 2 and 5 9 minutes; and 6x4, 80% 1RM, 2 and 5 minutes. Volume load was equalized between 10 protocols (1920 AU). Velocity loss and effort index (EI) attained during the session were 11 calculated. Movement velocity against the 60% 1RM and blood lactate concentration pre 12 post exercise were used to assess the mechanical and metabolic responses, respectively. 13 Results: RT protocols performed with heavy load (80% 1RM) resulted in a lower (P<.05) 14 total number of repetitions (ES=-2.44) and volume load (ES=-1.79) than the scheduled 15 ones when longer set configurations and shorter rest periods were used in the same 16 protocol (i.e., higher training density protocols). Protocols including higher number of 17 repetitions per set and shorter rest times induced higher velocity loss, EI, and lactate 18 concentrations than the rest of protocols. Conclusions: Our results suggest that RT 19 protocols with similar volume load but different training variables (i.e., intensity, number 20 of sets and repetitions, rest between sets) produce different responses. Implementing 21 shorter number of repetitions per set and longer rest interval length are recommended to 22 reduce the intra-session and post-session fatigue.
