摘要

目的:研究使用传统(TRA)和自动调节休息-再分配训练(ARRT)方法进行阻力训练时,男女在成绩和感觉疲劳方面的差异:12名接受过阻力训练的男性和12名女性分别完成了两次卧推训练,训练内容包括与负荷(75%的单次最大值)、训练量(24次)和总休息时间(240秒)相匹配的卧推训练。训练以平衡随机设计的方式进行,其中 TRA 包括 3 组 8 次重复,组间休息 120 秒;ARRT 采用个性化的组群组合、每组重复次数和组间休息,速度损失阈值为 20%。比较了 TRA 和 ARRT 对男女速度损失、单侧等长峰值力和疲劳评级(ROF)的影响:结果:与 TRA 相比,ARRT 期间的速度损失普遍较低(-0.47% [0.11%]),与女性相比,ARRT 对速度损失的缓解程度更高(-0.37% [0.15%])。与 TRA 相比,ARRT 后男性单侧等长峰值力下降幅度更小(-38.4 [8.4] N)。与女性相比,男性在 ARRT 后的 ROF 更低(-1.97 [0.55] AU)。此外,在两种情况下,男性的 ROF 均高于女性(1.92 [0.53] AU),ARRT 的 ROF 总体低于 TRA(-0.83 [0.39] AU):结论:与 TRA 相比,ARRT 方法可减少男女受试者的速度损失、峰值力损伤和 ROF。然而,男性受试者从 ARRT 方法中获得的急性期内收益更为明显。

The Autoregulation Rest-Redistribution Training Method Mitigates Sex Differences in Neuromuscular and Perceived Fatigue During Resistance Training.

Purpose: To examine the sex differences in performance and perceived fatigue during resistance training prescribed using traditional (TRA) and autoregulation rest-redistribution training (ARRT) approaches.

Methods: Twelve resistance-trained men and 12 women completed 2 sessions including the bench-press exercise matched for load (75% of 1-repetition maximum), volume (24 repetitions), and total rest (240 s). Sessions were performed in a counterbalanced randomized design with TRA consisting of 3 sets of 8 repetitions with 120-second interset rest and ARRT employing a personalized combination of clusters, repetitions per cluster, and between-clusters rest regulated with a 20% velocity-loss threshold. The effects of TRA and ARRT on velocity loss, unilateral isometric peak force, and rating of fatigue (ROF) were compared between sexes.

Results: The velocity loss was generally lower during ARRT compared with TRA (-0.47% [0.11%]), with velocity loss being mitigated by ARRT to a greater extent among males compared with females (-0.37% [0.15%]). A smaller unilateral isometric peak force decline was observed after ARRT than TRA among males compared with females (-38.4 [8.4] N). Lower ROF after ARRT than TRA was found among males compared to females (-1.97 [0.55] AU). Additionally, males reported greater ROF than females across both conditions (1.92 [0.53] AU), and ARRT resulted in lower ROF than TRA overall (-0.83 [0.39] AU).

Conclusions: The ARRT approach resulted in decreased velocity loss, peak force impairment, and ROF compared with TRA in both sexes. However, male subjects exhibited more pronounced acute within-session benefits from the ARRT method.
