Previous studies have shown significant improvement in muscle soreness and muscle function loss after 300-s foam rolling intervention two days after intense exercise. However, this duration is assumed to be too long, so investigating the effect of short-term duration foam rolling intervention on an eccentrically-damaged muscle is needed. This study aimed to eccentrically induce muscle damage in the leg extensors, and to detect the acute effect of 90-s foam rolling on muscle soreness and muscle function of the quadriceps muscle. We enrolled 17 healthy and nonathlete male volunteers. They performed a bout of eccentric exercise of the knee extensors with the dominant leg and received 90-s foam rolling intervention of the quadriceps two days after the eccentric exercise. The dependent variables were measured before the eccentric exercise (baseline), and before (preintervention) and after foam rolling intervention (postintervention), two days after the eccentric exercise. The results show that the preintervention muscle soreness and muscle strength values were significantly increased, compared with the baseline values, whereas the postintervention values were significantly decreased, compared with the preintervention values. Furthermore, 90-s of foam rolling intervention could improve muscle soreness and muscle function loss.
先前的研究表明，在剧烈运动两天后进行 300 秒的泡沫轴滚动干预，可显著改善肌肉酸痛和肌肉功能丧失。然而，这个持续时间被认为太长了，因此需要研究短期泡沫轴滚动干预对离心性损伤肌肉的影响。本研究旨在通过离心运动诱导腿部伸肌的肌肉损伤，并检测 90 秒泡沫轴滚动对股四头肌肌肉酸痛和肌肉功能的急性影响。我们招募了 17 名健康的非运动员男性志愿者。他们用优势腿进行了一次膝关节伸展的离心运动，然后在离心运动两天后对股四头肌进行 90 秒的泡沫轴滚动干预。依赖变量在离心运动前（基线）、离心运动前（干预前）和泡沫轴滚动干预后（干预后）进行测量。结果表明，与基线值相比，干预前的肌肉酸痛和肌肉力量值显著增加，而与干预前相比，干预后的肌肉酸痛和肌肉力量值显著降低。此外，90 秒的泡沫轴滚动干预可以改善肌肉酸痛和肌肉功能丧失。
