【摘要】:目的:分析肩袖損傷運動員扣球時肌肉發(fā)力順序,探討肩袖損傷的原因,為運動員糾正錯誤動作、提高技術(shù)水平、預(yù)防肩袖損傷提供參考依據(jù)。方法:利用MEGAWIN6000表面肌電測試儀對肩袖損傷和肩部無傷的排球運動員疲勞前后的扣球動作進行測試,比較發(fā)力順序的異同,分析肩袖損傷對動作控制的影響。結(jié)果:1)2組扣球發(fā)力各肌肉發(fā)力時刻占總動作時間百分比組間比較,疲勞前無傷組斜方肌中束和前鋸肌明顯大于有傷組,且差異具有非常顯著性;2)損傷組組內(nèi)比較,疲勞前斜方肌下束明顯大于疲勞后,且差異具有顯著性;3)損傷組僅在疲勞后主動上回旋肩胛骨再引臂,且沒有內(nèi)收預(yù)拉長;4)無傷組疲勞前后均會主動上回旋肩胛骨再引臂,且引臂前會內(nèi)收上臂預(yù)拉長肌肉。結(jié)論:1)肩袖損傷運動員斜方肌下束激活異常,肩胛骨不穩(wěn)定且主動運動滯后,肩峰下空間減小,容易引起撞擊導(dǎo)致肩袖損傷;2)無傷運動員斜方肌中束和前鋸肌激活明顯早、貢獻大,肩胛骨穩(wěn)定且主動運動積極,肩峰下空間相對增大,可有效避免撞擊損傷,內(nèi)收預(yù)拉長動作有效提高扣球效果;3)肩袖損傷運動員與無傷運動員扣球發(fā)力順序有明顯差異,肩袖損傷運動員動作環(huán)節(jié)過度減少,幅度縮小,影響扣球質(zhì)量且容易造成損傷。
[Abstract]:Objective: to analyze the order of muscle power when the athletes with rotator cuff injury spiked, to explore the causes of rotator cuff injury, to correct the wrong actions and to improve the technical level of the athletes. Methods: using MEGAWIN6000 surface electromyograph to test the spiking action before and after fatigue of volleyball players with rotator cuff injury and shoulder injury. The effect of rotator cuff injury on motion control was analyzed. Results compared with the percent of total action time, the median bundle and anterior serratus muscle of trapezius muscle in no injury group before fatigue were significantly larger than those in injured group. The difference was significant (P < 0.05). The inferior bundle of the anterior trapezius muscle was larger than that after fatigue, and the difference was significant only in the group of fatigue. And there was no adduction and prestretching. 4) in the no injury group, the shoulder blades were swung up before and after fatigue, and the muscles of the upper arm were prestretched. Conclusion: 1) abnormal activation of the inferior bundle of trapezius muscle was found in the rotator cuff injury athletes. The scapular bone is unstable and the active movement lags behind, the space of the subacromial is reduced, which is easy to cause the rotator cuff injury. (2) the medial bundle and anterior serratus muscle in the trapezius muscle of the uninjured athletes are activated earlier, the contribution is great, the scapular bone is stable and the active movement is active. The space under the acromial is relatively large, which can effectively avoid the impact injury, and can effectively improve the effect of spiking. (3) there are obvious differences in the order of spiking power between the players with and without the shoulder cuff injury, and the excessive reduction of the action links of the athletes with rotator cuff injury. Small amplitude, affect the quality of spiking and easy to cause damage.
