Although the comparison between self-managed rest and fixed rest periods in subjects experienced in lower-limb strength training has been investigated, the results remain unclear due to controversies among some studies. Therefore, the present study aimed to analyze the role of self-managed rest versus fixed rest in athletic performance, mean propulsive velocity, velocity loss, muscle oxygen saturation, and rest time in trained subjects; Thirteen subjects with a minimum of one year of training experience (age (years): 26.31 ± 3.84; height (cm): 175.46 ± 5.61; weight (kg): 79.24 ± 6.83) were randomly assigned to two groups (self-selected rest group [SR] = 7 and fixed rest group [FR] = 6). The subjects underwent a session for evaluation (one maximum repetition (1RM) estimation, familiarization, and data collection) and another day for a traditional strength training session for the back squat, consisting of five sets of four repetitions at 80% of 1RM. One group took a fixed 2 min break, while the other group managed their breaks autonomously (resuming when they felt ready to perform the next set at maximum velocity). Mean propulsive velocity (MPV) was monitored using a linear position transducer, and muscle oxygen saturation (SmO) was measured with a near-infrared spectroscopy device; Significant differences between the groups were found for the rest time between the first and second sets (SR 97.29 ± 23.70 seg vs. FR 120 ± 0.00 seg). However, no differences were found for MPV, velocity loss, or SmO; Given the similarities in performance and physiological outcomes between fixed and self-selected rest conditions, both can be used equally depending on the preferences and training goals of coaches and athletes.
尽管已经对下肢力量训练有经验的受试者进行自我管理休息和固定休息时间的比较研究，但由于一些研究之间存在争议，结果仍不明确。因此，本研究旨在分析自我管理休息与固定休息在训练有素的受试者的运动表现、平均推进速度、速度损失、肌肉氧饱和度和休息时间方面的作用；13名至少有一年训练经验的受试者（年龄（岁）：26.31±3.84；身高（厘米）：175.46±5.61；体重（千克）：79.24±6.83）被随机分为两组（自我选择休息组[SR]=7人，固定休息组[FR]=6人）。受试者进行了一次评估 session（一次最大重复次数（1RM）估计、熟悉和数据收集），另一天进行了一次传统的背部深蹲力量训练 session，包括以1RM的80%进行五组，每组四次重复。一组进行固定的2分钟休息，而另一组自主管理休息时间（当他们感觉准备好以最大速度进行下一组时恢复）。使用线性位置传感器监测平均推进速度（MPV），并用近红外光谱设备测量肌肉氧饱和度（SmO）；两组之间在第一组和第二组之间的休息时间存在显著差异（SR为97.29±23.70秒，而FR为120±0.00秒）。然而，在MPV、速度损失或SmO方面未发现差异；鉴于固定休息和自我选择休息条件下在表现和生理结果方面的相似性，两者均可根据教练和运动员的偏好及训练目标同等使用。
