发布时间：2018-09-05 16:06
【摘要】：目的腕痛为举重运动常见的伤病,选择性的放松屈伸肌能缓解大部分症状。目前国内外从肌肉骨关节平衡的角度去分析运动员腕痛的研究较少,而前臂屈伸肌肌力比例失调或许会导致举重运动员腕痛增加。通过力量训练人为改变举重运动员前臂的屈伸肌肌力,探讨前臂屈伸肌力比与举重运动员腕痛的关系。方法选取22名成都体育学院举重队运动员作为研究对象,随机分为屈肌干预组和伸肌干预组,运用KEISER 003020PP对受试者前臂屈伸肌肌力进行测试,根据肌力测试结果得出干预负荷,分别对屈、伸肌组进行6周力量训练干预,将两组干预前后腕痛频率、功能评分进行配对样本T检验,干预后屈肌组与伸肌组腕痛频率进行独立样本T检验,干预前后的腕痛频率、功能评分以及肌力比进行Pearson相关性分析。结果腕痛频率:屈、伸肌组右腕干预前后腕痛频率有显著差异(P0.05),屈肌组升高,伸肌组降低;左腕无显著差异。屈、伸肌组右腕干预后组间腕痛频率存在显著差异(P0.05),屈肌组高于伸肌组;左腕无显著差异。功能评分:屈、伸肌组干预前后腕关节功能评分存在显著差异(P0.05),屈肌组降低,伸肌组升高。相关性:干预前与干预后,肌力比与腕痛频率、功能评分不存在显著线性相关(P0.05)。结论举重运动员腕痛与前臂屈伸肌力比失调有关,前臂伸肌训练能改善举重运动员的腕痛程度,对腕痛的频率则无确切影响。
[Abstract]:Objective wrist pain is a common injury in weightlifting. Selective relaxation of flexion and extensor muscle can relieve most of the symptoms. At present, there is little research on carpal pain in athletes from the angle of muscle bone and joint balance, and the imbalance of muscle force ratio of forearm flexion and extensor muscle may lead to the increase of wrist pain in weightlifters. The relationship between forearm flexion and extensor muscle force ratio and wrist pain of weightlifters was discussed by means of strength training to change the muscle strength of forearm flexion and extensor muscle of weightlifters. Methods 22 athletes from the weightlifting team of Chengdu Institute of physical Education were randomly divided into flexor muscle intervention group and extensor muscle intervention group. KEISER 003020PP was used to test the forearm flexion and extensor muscle strength, and the intervention load was obtained according to the results of muscle strength test. The flexor and extensor groups were treated with strength training for 6 weeks respectively. The frequency of wrist pain and the score of function before and after intervention were tested by paired sample T test. After intervention, the frequency of wrist pain in flexor group and extensor group were tested by independent sample T test. The frequency of wrist pain, functional score and muscle strength ratio were analyzed by Pearson before and after intervention. Results the frequency of carpal pain in flexor and extensor group was significantly different before and after right wrist intervention (P0.05). The frequency of carpal pain increased in flexor group and decreased in extensor group, but there was no significant difference in left wrist. The frequency of carpal pain in flexor and extensor group was higher than that in extensor muscle group (P0.05), but there was no significant difference in left wrist. Functional score: flexion, extensor group before and after intervention there was significant difference in wrist function score (P0.05), flexor group decreased, extensor group increased. Correlation: there was no significant linear correlation between muscle strength ratio and wrist pain frequency and functional score before and after intervention (P0.05). Conclusion Carpal pain of weightlifters is related to the imbalance of forearm flexion and extensor muscle ratio. Forearm extensor muscle training can improve the degree of carpal pain of weightlifters, but has no definite effect on the frequency of carpal pain.
