The purpose of this study was to examine the effects of self-myofascial release (MFR) via foam rolling immediately following strenuous activity on acute fatigue-related impairments of muscular performance. Healthy male ( = 16) and female ( = 9) subjects visited the laboratory three separate times. During visit 1, subjects were familiarized with performance testing procedures and the foam rolling and fatigue protocols. For visits 2 and 3, subjects were (T1) assessed for vertical jump height, velocity, and power and dynamic reaction time (DRT). Subjects then performed the exercise fatigue protocol, followed by either a foam rolling treatment (MFR) or seated rest (CON). Immediately after, subjects repeated the performance tests (T2). CON resulted in a greater percent decline from T1⁻T2 for average power ( = 0.03), average velocity ( = 0.02), and peak power ( = 0.03) than the MFR treatment. No between-treatment differences were detected for %∆ vertical jump height ( = 0.14) or DRT ( = 0.20). According to magnitude-based inference analysis, MFR is likely beneficial in attenuating fatigue-induced kinematic decrements (i.e., power and velocity). Based on magnitude-based inference analysis, MFR is "possibly beneficial" with respect to mitigating acute fatigue-related impairment of jump height and dynamic reaction time. Results demonstrate the plausible short-term benefits of foam rolling on muscular performance decrements associated with acute muscular fatigue from exercise.
本研究的目的是检验在剧烈活动后立即通过泡沫轴进行自我肌筋膜放松（MFR）对肌肉性能急性疲劳相关损伤的影响。健康男性（n = 16）和女性（n = 9）受试者分三次前往实验室。在第一次访问期间，受试者熟悉了性能测试程序以及泡沫轴放松和疲劳方案。在第二次和第三次访问中，对受试者进行（T1）垂直跳高度、速度、功率和动态反应时间（DRT）的评估。然后受试者执行运动疲劳方案，随后进行泡沫轴放松治疗（MFR）或坐姿休息（CON）。之后，受试者立即重复性能测试（T2）。与MFR治疗相比，CON组从T1到T2的平均功率（p = 0.03）、平均速度（p = 0.02）和峰值功率（p = 0.03）下降百分比更大。在垂直跳高度的%∆（p = 0.14）或DRT（p = 0.20）方面未检测到治疗组间差异。根据基于量级的推断分析，MFR可能有助于减轻疲劳引起的运动学下降（即功率和速度）。基于量级的推断分析，MFR在减轻与跳跃高度和动态反应时间相关的急性疲劳损伤方面“可能有益”。结果表明，泡沫轴放松对与运动引起的急性肌肉疲劳相关的肌肉性能下降具有合理的短期益处。
