To examine the reproducibility of the Perceived Recovery Status (PRS) scale in football players and describe the time course of the PRS in response to a football match.
Twenty trained youth players (mean [SD] age = 16.2 [1.2] y, height = 1.75 [0.07] m, body mass = 64.0 [7.8] kg) took part in the study. PRS was collected -2 h and -30 min before and +15 min, +3 h, and +24 h after an international football match. Players were categorized into 2 groups based on their playing time (≤45 and 90 min).
Reproducibility of the PRS was high (intraclass correlation coefficient = .83, typical error = 0.59, coefficient of variation = 9.9%) between the 2 prematch measures. Overall, PRS was lower at +15 min (4.0 [1.5]; P < .01, effect size = 2.2) and +3 h (4.7 [1.6]; P < .01, effect size = 1.5) compared with -30 min (7.1 [1.3]); +15 min was lower than +24 h (6.1 [1.3]; P < .01, effect size = 1.5). No differences between groups for PRS scores at any of the time points were found.
The PRS is a reproducible tool for monitoring perceptions of recovery to football activity and is sensitive to time-course changes relating to a match. The scale is an easy and efficient tool that can be used to monitor an aspect of recovery.
检验足球运动员感知恢复状态（PRS）量表的可重复性，并描述 PRS 对足球比赛的反应时间过程。
20 名经过训练的青年球员（平均[标准差]年龄=16.2[1.2]岁，身高=1.75[0.07]米，体重=64.0[7.8]公斤）参与了研究。PRS 在国际足球比赛前 2 小时和 30 分钟以及比赛后 15 分钟、3 小时和 24 小时进行收集。根据球员的上场时间（≤45 和 90 分钟）将他们分为 2 组。
PRS 在 2 次赛前测量之间具有较高的可重复性（组内相关系数=0.83，典型误差=0.59，变异系数=9.9%）。总体而言，与-30 分钟时（7.1[1.3]）相比，+15 分钟（4.0[1.5]；P<.01，效应量=2.2）和+3 小时（4.7[1.6]；P<.01，效应量=1.5）时 PRS 较低；+15 分钟时比+24 小时（6.1[1.3]）时更低（P<.01，效应量=1.5）。在任何时间点，两组之间的 PRS 评分均无差异。
PRS 是监测足球活动后感知恢复的一种可重复的工具，对与比赛相关的时间过程变化敏感。该量表是一种简单有效的工具，可用于监测恢复的一个方面。
