Cluster Versus Rest-Redistribution Training: Similar Improvements in Neuromuscular Capacities in Female Team-Sport...

This study's purpose was to investigate the midterm effects of alternative set configurations (cluster [CL] and rest redistribution [RR]) on lower- and upper-body neuromuscular capacities in female athletes.

Twenty team-sport female athletes were randomly assigned to a CL (n = 10) or RR (n = 10) training group. The study protocol comprised 2 pretests, 12 training sessions, and a posttest. Both groups engaged in identical exercises (squat and bench press), load intensity (75% of 1-repetition maximum), and volume (18 repetitions per exercise). The distinction between the groups lay in the total session rest time: The CL group had 23 minutes (3 sets of 6 repetitions with 30 s of intraset rest every 2 repetitions and 3 min of interset rest), whereas the RR group had 17 minutes (9 sets of 2 repetitions with 45 s of interset rest). Countermovement-jump height and load-velocity relationship variables (load-intercept, velocity-intercept, and area under the load-velocity relationship line) were assessed during the squat and bench-press exercises.

All dependent variables revealed greater values at posttest compared with pretest (P ≤ .040; averaged Hedges g = 0.35 for CL and 0.60 for RR), but time × group interactions never reached statistical significance (P ≥ .144). Likewise, the comparison of the magnitude of changes between the 2 groups revealed only trivial differences, except for a small greater change in bench-press area under the load-velocity relationship line for RRG (Hedges g = 0.40).

RR is a more efficient strategy than CL for inducing strength gains in female athletes.
