Abstract

Purpose: 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.

Method: 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.

Results: 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).

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

集束训练与休息再分配训练:女性团队运动运动员神经肌肉能力的类似改善。
目的:本研究的目的是探讨可选组配置(聚类[CL]和休息再分配[RR])对女运动员下半身和上半身神经肌肉能力的中期影响。方法:20名团队运动女运动员随机分为CL (n = 10)和RR (n = 10)训练组。研究方案包括2次前测、12次训练和1次后测。两组进行相同的锻炼(深蹲和卧推),负荷强度(最大1次重复的75%)和体积(每组18次重复)。各组之间的区别在于总休息时间:CL组为23分钟(3组6次重复,每2次重复30秒,兴趣休息3分钟),而RR组为17分钟(9组2次重复,兴趣休息45秒)。在深蹲和卧推练习中评估反动作-跳跃高度和负载-速度关系变量(负载-截距,速度-截距和负载-速度关系线下的面积)。结果:所有因变量的后测值均高于前测值(P≤0.040;CL的平均对冲系数g = 0.35, RR的平均对冲系数g = 0.60),但时间×组相互作用未达到统计学意义(P≥0.144)。同样,比较两组之间的变化幅度,除了RRG的载荷-速度关系线下的卧压面积变化较小(Hedges g = 0.40)外,差异很小。结论:在诱导女运动员力量增加方面,RR比CL更有效。
