【摘要】：目的:观察泡沫轴练习对运动性肌肉疲劳恢复过程中肌肉功能变化的影响,为该方法在实际中的运用提供依据。方法:选取44名男性大学生,随机分为泡沫轴组(n=22)和空白组(n=22),运用深蹲负荷造成下肢伸膝肌群运动性肌肉疲劳模型。泡沫轴组在造模运动后30分钟内接受泡沫轴滚压。分别于造模前、造模后0.5 h、24 h和48 h四个时相通过等长和等速向心两个测试模式分别测定峰力矩和等速模式下的总做功。结果:(1)峰力矩在造模后0.5 h,两组均比造模前显著性降低(P0.05),24 h泡沫轴组具有高于空白组的趋势,但无显著性差异(P0.05),48 h时泡沫轴组明显高于空白组(P0.05)且基本恢复至造模前水平;(2)在造模后0.5 h,两组的等速向心做功均比造模前显著性降低(P0.05),24 h时泡沫轴组具有高于空白组的趋势,但无显著性差异(P0.05),48h时泡沫轴组做功能力明显高于空白组(P0.05)且基本恢复至造模前水平(P0.05)。结论:(1)运动性肌肉疲劳可以导致肌肉最大力量和做功能力的显著下降,这种功能下降在48小时之内都不能完全恢复;(2)泡沫轴练习能够改善运动性肌肉疲劳后肌肉的最大力量和做功能力,加快疲劳后肌肉功能的恢复;(3)泡沫轴练习对运动性肌肉疲劳的影响表现出时间的延迟性和效果的累积性,其干预效果在24 h后显现,在48 h后效果显著。
[Abstract]:Aim: to observe the effect of foam axis exercise on muscle function during the recovery of exercise muscle fatigue, and to provide the basis for the application of this method in practice. Methods: Forty-four male college students were randomly divided into foam shaft group (nong22) and blank group (nong22). The exercise muscle fatigue model of extensor knee muscle group of lower extremities was induced by squat load. Foam shafts are rolled within 30 minutes after modeling. The peak torque and the total work in the isokinetic mode were measured by isometric and isokinetic methods before, 0.5 h and 48 h after modeling, respectively. Results: (1) at 0.5 h after modeling, the peak torque of the two groups was significantly lower than that of the control group (P0.05). The peak torque of the 24 h foam shaft group was higher than that of the blank group. But there was no significant difference (P0.05) at 48 h, the foam shaft group was significantly higher than the blank group (P0.05) and basically recovered to the pre-model level; (2) at 0.5 h after modeling, the concentric work of the two groups was significantly lower than that before modeling (P0.05) at 24 h, the foam shaft group had a higher trend than the blank group. But there was no significant difference (P0.05) at 48h, the work ability of foam shaft group was significantly higher than that of blank group (P0.05) and basically recovered to the pre-model level (P0.05). Conclusion: (1) Exercise-induced muscle fatigue can significantly decrease the maximum muscle strength and the ability to do work. This decline in function cannot be fully recovered within 48 hours; (2) foam axis exercises can improve muscle maximum strength and ability to do work after exercise muscle fatigue. (3) the effect of foam axis exercise on exercise muscle fatigue showed time delay and cumulative effect. The intervention effect was obvious after 24 hours and 48 hours.
