【摘要】：背景:青少年体操动作技术训练越来越趋于科学化、系统化。利用科学的诊断方法来确定运动员的关节肌肉力量特征并针对性地实施训练方案,目前已成为青少年体操动作技术训练的主流趋势。目的:探索青少年男子体操运动员躯干、髋和膝关节的等速肌力特征。方法:以现役辽宁省16名青少年男子体操运动员为研究对象,运用ISOMED2000等速肌力测试系统对运动员的躯干环节进行30,60,180(°)/s的等速肌力测试,并对髋、膝关节进行60,180,300(°)/s的等速肌力测试。结果与结论:(1)躯干环节30,60,180(°)/s的屈伸肌比值分别为91.36±1.25,87.77±3.74,78.20±4.70,呈逐渐减小趋势;(2)髋关节60,180,300(°)/s左侧的屈伸肌比值分别为65.55±4.38,66.92±3.22,68.18±2.82,呈逐渐增大趋势;右侧分别为57.40±4.43,65.73±1.07,64.15±5.55,呈先增大后减小趋势;另外,在60(°)/s下左侧屈肌肌力显著高于右侧,而右侧伸肌肌力显著高于左侧(P0.05);(3)膝关节60,180,300(°)/s下左侧的屈伸肌比值分别为50.88±4.98,54.75±4.51,58.80±7.93;右侧分别为51.55±4.30,55.20±5.08,58.43±5.93,均呈逐渐增大趋势;3个速度下左右侧屈伸肌群肌力差异均无显著性意义(P0.05);(4)结果提示,腰背环节快速力量特别是屈肌存在严重不足,伸肌的基础力量比较薄弱;髋关节左侧屈肌基础力量较大而右侧伸肌基础力量较大,屈肌的快速力量比较薄弱,左右侧肌力存在失衡现象;膝关节左右侧肌力比较均衡,左侧屈肌的快速力量和两侧伸肌的基础力量有一定欠缺。
[Abstract]:Background: the technical training of young gymnastic movements is becoming more and more scientific and systematic. Using the scientific diagnostic method to determine the characteristics of athletes' joint muscle strength and to carry out the training program pertinently has become the mainstream trend of the young gymnastic movement technique training. Objective: to explore the isokinetic characteristics of trunk, hip and knee of adolescent male gymnasts. Methods: sixteen male male gymnasts in active service in Liaoning province were studied. The isokinetic muscle strength of the trunk of the athletes was measured by ISOMED2000 isokinetic muscle strength test system. The isokinetic muscle strength of the hip and knee joints was measured with the isokinetic muscle strength of 60180300 (掳/ r / s). At 60 掳/ s, the muscle strength of the left flexor was significantly higher than that of the right. But the muscle strength of the right extensor muscle was significantly higher than that of the left side (P 0.05 / 3)) the ratio of flexion and extensor of the right side was 50.88 卤4.98 卤4.51 卤58.80 卤7.93, and the right was 51.55 卤4.3055.20 卤5.058.43 卤5.93 respectively, and the difference of the muscle strength between the left and the right flexion and extensor group was not significant (P0.05 / 4). There are serious deficiencies in the fast strength of the lumbar and back link, especially in the flexor muscle, the basic strength of the extensor muscle is relatively weak, the basic strength of the flexor muscle on the left side of the hip joint is greater than that of the right extensor muscle, and the fast strength of the flexor muscle is relatively weak. The muscle strength of the left and right sides is unbalanced, the muscle strength of the left and right knee is relatively balanced, the fast strength of the left flexor muscle and the basic strength of the bilateral extensor muscle are deficient.
