摘要
分析久坐大学生在进行不同时长泡沫轴滚动后腘绳肌柔韧性的变化,以探究泡沫轴滚动时长对久坐大学生腘绳肌柔韧性的影响.实验选取13名久坐大学生,在不同时段分别进行泡沫轴滚动干预,并在干预后即刻、5 min及10 min后进行坐位体前屈测试.采用配对样本t检验,对干预前后及不同滚动时长间的腘绳肌柔韧性进行参数检验.研究结果如下:干预后即刻,滚动10 s、30 s、60 s的腘绳肌柔韧性相较于干预前均有提高,差异具有统计学意义;但不同滚动时长组间差异未表现出统计学意义;干预后5 min,滚动10 s、30 s、60 s的腘绳肌柔韧性相较于干预前亦均有提高,差异具有统计学意义,且不同滚动时长组间差异不具有统计学意义;干预后10 min,滚动10 s、30 s、60 s的腘绳肌柔韧性相较于干预前依然均有提高,差异具有统计学意义,不同滚动时长组间差异未见统计学意义.综上所述,10 s、30 s、60 s时长的泡沫轴滚动均能有效提升腘绳肌柔韧性,且效果相近.此外,泡沫轴滚动引起的腘绳肌柔韧性改善能够持续一段时间.
Abstract
This study aimed to explore the effect of foam rolling on hamstring flexibility among sedentary college students by analyzing changes in hamstring flexibility after foam rolling for different durations.Thirteen sedentary college students were selected for the experiment,underwent foam rolling at different time and performed sit-and-reach tests immediately,after 5 minutes,and after 10 minutes.Paired-samples T-tests were used to examine the parameters of hamstring flexibility before and after the rolling and between different time durations.The research results are as follows:Immediately after intervention,hamstring flexibility after rolling for(10 s,30 s,60 s)after intervention has improved compared to pre-intervention,and the difference was statistically significant;Five minutes after the intervention,hamstring flexibility also significantly improved from pre-intervention for all rolling durations(10 s,30 s,60 s),and the difference was statistically significant.However,the difference between groups with different rolling durations was not statistically significant;Ten minutes after the intervention,hamstring flexibility continued to show significant improvements from pre-intervention for all rolling durations(10 s,30 s,60 s),and again,and the difference was statistically significant.There was no statistically significant difference between groups with different rolling durations.In conclusion,Foam rolling for 10 s,30 s,and 60 s durations can effectively improve the flexibility of hamstring muscles,and the effect is similar.Additionally,the improvements in hamstring flexibility induced by foam rolling persisted for a period of time.
