Abstract

Background: Estimating repetitions in reserve (RIR) has been established as a valid and practical method for monitoring set configuration concerning proximity to failure in resistance training. However, factors such as sex and exercise equipment could interfere with the estimation process. Therefore, this study aimed to determine the influence of sex (female vs male) and exercise equipment (free-weight vs Smith machine) on the RIR estimation at different relative loads during the bench press exercise.

Hypothesis: Men would be more accurate than women in the RIR estimation, and participants would better perceive their actual effort at the Smith machine compared with the free-weight bench press exercise.

Study design: Repeated measures design.

Level of evidence: Level 3.

Methods: In a counterbalanced order, recreationally trained participants (12 female, 14 male) performed 2 identical sessions with the free-weight bench press exercise in 1 week and 2 identical sessions with the Smith machine bench press exercise in another week (first session for familiarization and second session for validity analysis). In each session, participants performed single sets of repetitions to failure against 3 relative loads (65%, 75%, and 85% of the 1-repetition maximum [1RM]).

Results: Results revealed a significant interaction between RIR and sex at 65% 1RM (P < 0.01; women: -1.2 [-1.7 to -0.6] repetitions; men: -0.1 [-0.6 to 0.3] repetitions), and between RIR and exercise equipment at 65% 1RM (P < 0.01; free-weight: -1.1 [-1.5 to -0.6] repetitions; Smith machine: -0.2 [-0.6 to 0.2] repetitions), but not at 75% and 85% 1RM.

Conclusions: RIR estimation is a valid method for monitoring set configuration. However, this method tends to underestimate RIR at 65%1RM with female athletes and in the free-weight exercise for both sexes.

Clinical relevance: Strength and conditioning coaches should help their athletes understand effort awareness in the aforementioned context.

估算卧推运动中的储备重复次数：我们是否应该考虑性别和运动器材？

背景：估算储备重复次数（RIR）已被确定为一种有效而实用的方法，用于监测阻力训练中接近失败的成套配置。然而，性别和运动器材等因素可能会干扰估算过程。因此，本研究旨在确定性别（女性 vs 男性）和运动器材（自由重量 vs 史密斯器械）对卧推练习中不同相对负荷下的 RIR 估算的影响：研究设计：重复测量设计：重复测量设计：证据等级：3 级：按照平衡顺序，接受过娱乐训练的参与者（12 名女性，14 名男性）在一周内进行了两次相同的自由重量卧推练习，在另一周内进行了两次相同的史密斯机卧推练习（第一次练习用于熟悉，第二次练习用于有效性分析）。在每次训练中，参与者在 3 种相对负荷（单次最大负重的 65%、75% 和 85%）下进行单组重复训练，直至失败：结果显示，在 65% 1RM 时，RIR 与性别之间存在明显的交互作用（P < 0.01；女性：-1.2 [-1.7 至 -0.6]次；男性：-0.1 [-0.6 至 0.3]次）。3]次），以及在65% 1RM时RIR与运动器械之间的关系（P < 0.01；自由重量：-1.1 [-1.5 to -0.6]次；史密斯机：-0.2 [-0.6 to 0.2]次），但在75%和85% 1RM时没有关系：结论：RIR 估算是监测成套动作配置的有效方法。结论：RIR 估计是监测成套动作配置的有效方法，但这种方法往往会低估女性运动员在 65%1RM 时的 RIR，而且在自由重量练习中，男女运动员的 RIR 都会被低估：临床意义：力量与体能教练应帮助运动员了解在上述情况下的努力意识。
