Although a variety of tools to monitor recovery have been developed, many are impractical for daily use due to cost, time, and challenges with interpretation. The Perceived Recovery Status (PRS) scale was recently developed as an expeditious, noninvasive tool to assess recovery status. While PRS has been strongly associated with repeated sprinting performance, a paucity of research exists relating PRS and performance recovery following resistance exercise.
The purpose of this study was to evaluate the sensitivity of PRS as a subjective marker of recovery up to 72 hours after a high-volume back-squat protocol.
Eleven resistance-trained men reported to the laboratory on 5 separate occasions (1 familiarization session and 4 testing sessions). The first testing session was considered the baseline session and consisted of a nonfatiguing performance assessment (ie, countermovement jumps and back squats) and a fatiguing back-squat protocol of 8 sets of 10 at 70% 1-repetition maximum separated by 2 minutes of recovery. Participants returned 24, 48, and 72 hours following baseline to provide a PRS rating and complete the performance assessment.
Repeated-measures correlations revealed strong associations between PRS countermovement jump (r = .84) and mean bar velocity (r = .80) (both P < .001).
The current findings suggest that PRS can be used as a method to effectively assess daily recovery following a fatiguing bout of resistance exercise. Practitioners are cautioned that the relationship between PRS and performance recovery is individualized, and equivalent PRS scores between individuals are not indicative of similar recovery.
尽管已经开发出了多种监测恢复情况的工具,但由于成本、时间和解释方面的挑战,许多工具并不实用。最近开发的感知恢复状态(PRS)量表是一种快速、非侵入性的工具,用于评估恢复状态。虽然 PRS 与重复冲刺表现密切相关,但关于 PRS 与阻力训练后性能恢复之间的研究很少。
本研究的目的是评估 PRS 作为一种主观的恢复标志物的敏感性,直到高容量深蹲方案后 72 小时。
11 名阻力训练男性在 5 个不同的场合(1 次熟悉会议和 4 次测试会议)向实验室报告。第一次测试会议被认为是基线会议,包括非疲劳性能评估(即,反跳跳和深蹲)和疲劳深蹲方案,共 8 组,每组 10 次,70%的 1 重复最大,间隔 2 分钟恢复。参与者在基线后 24、48 和 72 小时返回,提供 PRS 评分并完成性能评估。
重复测量相关性显示 PRS 反跳跳(r =.84)和平均杠铃速度(r =.80)之间存在强烈关联(均 P <.001)。
目前的研究结果表明,PRS 可用于有效评估疲劳阻力训练后日常恢复情况。从业者应注意,PRS 与性能恢复之间的关系是个体化的,个体之间的等效 PRS 分数并不表示相似的恢复。
