Abstract

Purpose: In a rested state, foam rolling has been shown to improve blood flow to the working tissues. When inducing post-activation performance enhancement (PAPE), previous research suggests a longer recovery period between the conditioning activity and performance assessment in weaker participants (back squat <2.0 × body mass). It is possible that a cool-down effect may take place between the conditioning activity and performance assessment for these participants. Therefore, the purpose of this investigation was to determine if foam rolling could help mitigate any cool-down effect to help participants capitalize on PAPE. Methods: Seventeen physically active participants completed baseline jumps followed by rest (control), back squat exercise (heavy squats), rest and foam rolling (FR), and heavy squats followed by foam rolling (combo). VJ performance was assessed three times post-treatment with 2 min between each assessment. Results: VJ height and impulse were greater at baseline than at any other time point across all sessions (p < .001). Impulse for the control and FR sessions were greater than the squats session (p < .015). Impulse for the combo session was less than the FR session (p = .04). Conclusions: Foam rolling did not have a significant impact on attenuating any cool-down effect. In addition, our heavy squats protocol appears to induce too much fatigue that possibly masked the effects of PAPE.

重负荷后蹲和泡沫滚揉对垂直跳跃成绩的急性影响
目的:事实证明,在休息状态下,泡沫滚动可改善工作组织的血流量。以前的研究表明,在诱导活动后成绩提高(PAPE)时,体质较弱的参与者在调节活动和成绩评估(深蹲方法)之间需要较长的恢复期:17 名身体活跃的参与者分别完成了基线跳跃后休息(对照组)、深蹲运动(大深蹲)、休息和泡沫滚动(FR)以及大深蹲后泡沫滚动(组合)。治疗后对 VJ 性能进行三次评估,每次评估间隔 2 分钟。结果显示在所有疗程中,基线时的 VJ 高度和冲力均大于其他任何时间点(P P = .04)。结论泡沫滚揉对减弱冷却效果没有显著影响。此外,我们的重蹲方案似乎引起了过多的疲劳,可能掩盖了 PAPE 的效果。

期刊介绍: Research Quarterly for Exercise and Sport publishes research in the art and science of human movement that contributes significantly to the knowledge base of the field as new information, reviews, substantiation or contradiction of previous findings, development of theory, or as application of new or improved techniques. The goals of RQES are to provide a scholarly outlet for knowledge that: (a) contributes to the study of human movement, particularly its cross-disciplinary and interdisciplinary nature; (b) impacts theory and practice regarding human movement; (c) stimulates research about human movement; and (d) provides theoretical reviews and tutorials related to the study of human movement. The editorial board, associate editors, and external reviewers assist the editor-in-chief. Qualified reviewers in the appropriate subdisciplines review manuscripts deemed suitable. Authors are usually advised of the decision on their papers within 75–90 days.
