摘　　要：泡沫轴滚动在激活神经肌肉的同时,可以提高肌肉柔韧性,但滚动时长过久也可能会有损力量表现。12名女性大学生排球运动员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、15 min后进行纵跳摸高(CMJ)测试。使用配对样本t检验对数据进行参数检验。研究结果:1)干预后即刻,滚动30 s、60 s后的CMJ较干预前出现显著提高,但90 s的CMJ出现显著下降。与滚动30 s相比,滚动60 s后的CMJ出现显著提高。2)干预5 min后,滚动90 s的CMJ较干预前出现显著下降。与滚动60 s相比,滚动90 s的CMJ出现显著下降。3)干预15 min后,滚动30 s、60 s、90 s后的CMJ较干预前均出现显著下降。与滚动60 s相比,滚动90 s后的CMJ出现显著下降。30 s、60 s的泡沫轴滚动能够提高干预后即刻运动员的纵跳表现,但是90 s的泡沫轴滚动会有损纵跳表现。同时,泡沫轴滚动的热身效果会随着时间增长出现下降。Appropriate duration foam rollings can enhance muscle flexibility while activating neuromuscular pathways,but prolonged rolling may compromise strength performance.Twelve female college volleyball players underwent foam rolling at different times,followed by immediate,5-minutes,and 15-minutes countermovement jump(CMJ)tests after the rolling.A paired-samples T-test was employed to analyze the data.Research results 1)CMJ heights significantly increased after immediate,30s and 60s foam rolling compared to before intervention,but significantly decreased after 90s.Compared to 30-seconds rolling,CMJ heights significantly increased after rolling for 60s;2)After 5 minutes of intervention,CMJ heights significantly decreased after 90-seconds foam rolling compared to before intervention.When compared to 60s rolling,CMJ heights significantly decreased after rolling for 90s;3)After 15minutes foam rolling,CMJ heights significantly decreased after 30s,60s,and 90-s of foam rolling compared to before intervention.CMJ heights significantly decreased after rolling for 90s compared to rolling for 60s.30s and 60s of foam rolling can improve athletes'immediate CMJ performance immediately after intervention,whereas 90s rolling is detrimental to it.At the same time,the warming-up effect of foam rolling diminishes over time.
