To determine the effect of vibrating rollers on skin blood flow after running for recovery from muscle fatigue.
23 healthy runners, aged between 20 to 45 years, participated in a crossover trial. Muscle fatigue was induced by running, and recovery using a vibrating roller was determined before and after the intervention. Each subject was measured at three time points (prerun, postrun, and postroller) to compare skin blood flow perfusion and blood flow oscillation at the midpoint of the dominant gastrocnemius muscle. The results show that blood perfusion is greater when a vibrating roller is used than a foam roller, but there is no statistical difference. The analysis of blood flow oscillation shows that vibrating rollers induce 30% greater endothelial activation than a foam roller. Vibrating rollers significantly stimulate the characteristic frequency for myogenic activation ( < 0.05); however, the effect size is conservative.
确定跑步后使用振动滚轮对肌肉疲劳恢复时皮肤血流的影响。
23 名年龄在 20 至 45 岁之间的健康跑步者参加了一项交叉试验。通过跑步诱发肌肉疲劳，并用振动滚轮在干预前后进行恢复。在三个时间点（跑步前、跑步后和使用滚轮后）对每个受试者进行测量，以比较优势比目鱼肌中点的皮肤血流灌注和血流振荡。结果表明，与使用泡沫辊相比，使用振动辊时的血液灌注量更大，但无统计学差异。血流振荡分析表明，振动辊比泡沫辊诱导 30%更大的内皮细胞激活。振动辊显著刺激肌源性激活的特征频率（<0.05）；然而，效果大小是保守的。
