【摘要】：研究目的：本研究旨在通过测试普通大学生的动态平衡能力，结合同步表面肌电信号收集，加上踝关节肌力训练，研究踝关节相关肌肉在平衡调节时的活动情况以及肌力改变对动态平衡能力的贡献性，以了解踝关节肌肉活动和肌力与动态平衡能力的关系及机制。研究方法：选择武汉体育学院健康科学学院大三的本科生为研究对象，选择同一个班的16名男生为实验受试者，随机分为两组每组8人，进行两种测试和一种训练。包括平衡能力测试，其中又分为单脚稳定度限制测试los和单脚稳定性测试asl，在biodex balancesystem上进行。平衡能力测试同时收集同步肌电信号，用ME6000T16表面肌电测试系统收集。测试组在第一次测试之后进行为期六周，每周2次的等速力量训练，在biodexsystem-4等速测试仪上进行。对照组也进行两次平衡能力测试，中间不进行任何干预，间隔时间为测试组整个训练的周期。结论：（1）通过等速踝关节跖屈背屈，内翻外翻30°／s和60°／s提高踝关节跖屈背屈，内翻外翻的肌力和做功能力，可使平衡能力测试的水平显著得到提高。（2）腓肠肌后段,腓肠肌中段前胫骨肌,比目鱼肌，踝伸肌群，的不同组合的肌力分别对与稳定度限制测试中的综合控制能力有不同的高作用率，并且方程有显著性。与稳定度限制测试中的测试完成时间缺少高度的方程拟合度，并且方程无显著性。与单脚稳定性测试的综合摆动，前后摆动指数有高方程拟合度，，并且方程有显著性，与左右摆动指数方程拟合度弱，并且方程无显著性。（3）随着稳定性限制测试等级的升高，平衡能力指数与肌肉的IEMG、MF拟合度组合减少，概率降低。此测试难度4的单脚稳定性测试有稳定的IEMG、MF拟合度。（4）同步肌电测试指标IEMG在稳定度限制测试和单脚稳定性测试中，存在与成绩成正相关趋势的可能，MF与成绩成负相关的可能，单脚稳定性测试中趋势尤其明显。
[Abstract]:Objectives of the study:. The purpose of this study was to test the dynamic balance ability of college students, combined with synchronous surface electromyography (EMG) signal collection and ankle strength training. In order to understand the relationship and mechanism between ankle muscle activity and dynamic balance ability, the movement of ankle muscle and the contribution of muscle strength change to dynamic balance ability were studied in order to understand the relationship between ankle muscle activity and dynamic balance ability. Research methods:. The undergraduate students of Wuhan Institute of physical Education and Health Sciences were selected as the research subjects, and 16 male students from the same class were selected as the subjects. They were randomly divided into two groups of 8 people each, two kinds of tests and one kind of training, including the balance ability test. It is divided into one foot stability restriction test (los) and one foot stability test (ASL) on biodex balancesystem. The balance ability test also collects synchronous EMG signals. After the first test, the test group received isokinetic strength training twice a week for six weeks. The control group was also tested twice on the biodexsystem-4 isokinetic tester. There was no intervention and the interval was the whole training period of the test group. Conclusion:. 1) through isokinetic ankle metatarsal flexion, varus valgus 30 掳/ s and 60 掳/ s, the muscle strength and work ability of ankle metatarsal flexion and varus valgus can be improved significantly. 2) the muscle strength of the posterior segment of gastrocnemius muscle, anterior tibial muscle of gastrocnemius muscle, soleus muscle, and extensor malleolus group has different high effects on the comprehensive control ability in the stability restriction test. And the equation is significant. It is lack of high degree of equation fitting with the test completion time in the stability restriction test, and the equation has no significance. With the integrated swing of the single leg stability test, the front and back swing index has high equation fitting degree. Moreover, the equation is significant, weak with the left and right swing index equation, and the equation has no significance. 3) with the increase of the stability limit test grade, the combination of the balance ability index and the muscle IEMGN MF fit degree decreased, and the probability decreased. (4) in the stability restriction test and the monopod stability test, there is a possibility that the positive correlation between MF and the achievement is negative, especially in the monopod stability test, which is the index of synchronous electromyography (IEMG).
