Abstract：
UNASSIGNED: This intervention study aimed to evaluate how the use of Foam Roller (FR) as a recovery strategy affects water polo performance after a seven-week (28-session) program.
UNASSIGNED: A randomized controlled trial.
UNASSIGNED: Thirty water polo players (14 male amateur players and 16 female sub-elite players) were assigned by means of sealed opaque envelopes to the control group (CG) or Foam Roller Group (FRG) and performed the same total number and intensity of training sessions. Test protocols were performed before (pretest), in-test (week 5), and after the intervention period (posttest). These included water polo-specific performance tests such as in-water boost, throwing speed, and 20 m sprint swimming tests. In addition, during the intervention, heart rate (HR), the scale of perceived exertion of the session (sRPE), and total quality recovery scale (TQR) data were recorded.
UNASSIGNED: There were no differences in the baseline values in any of the variables analyzed between CG and FRG. A small decrease in in-water boost was observed in CG (-2%, ES = -0.35 [-0.95: 0.26], p = 0.016, very likely small) and in FRG (-2%, ES = -0.33 [-0.93: 0.27], p = 0.021, likely small). No significant changes were found in either the 20 m swim test or the throwing test in CG and FRG. No clear differences among groups and weeks were found in sRPE, TQR and HR.
UNASSIGNED: The findings indicate that the use of FR as a recovery tool after training and matches is not useful in water polo players.

摘要：
■这项干预研究旨在评估使用FoamRoller（FR）作为恢复策略如何在为期7周（28次）的计划后影响水球性能。
■一项随机对照试验。
■通过密封的不透明信封将30名水球运动员（14名男性业余运动员和16名女性次精英运动员）分配给对照组（CG）或泡沫辊组（FRG），并进行相同的训练总次数和强度。测试方案在(预测试)之前进行，在测试中（第5周），和干预期（后测）后。这些包括水球特定性能测试，如水中提升，投掷速度,和20米短跑游泳测试。此外,在干预期间,心率(HR),会话的感知努力程度(sRPE)，并记录总质量恢复量表(TQR)数据。
■在CG和FRG之间分析的任何变量中，基线值都没有差异。在CG中观察到水中增加的少量减少(-2%，ES=-0.35[-0.95:0.26],p=0.016，很可能很小)，在FRG中(-2%，ES=-0.33[-0.93:0.27]，p=0.021，可能很小）。在20m游泳测试或CG和FRG的投掷测试中均未发现显着变化。sRPE在组间和周之间没有明显差异，TQR和HR。
■研究结果表明，在训练和比赛后使用FR作为恢复工具对水球运动员没有用。
