我国优秀自由式滑雪空中技巧运动员躯干肌力与专项成绩关系研究
Relationship between Specific Performance and Trunk Muscle Strength of China Elite Freestyle Skiing Aerials Athletes
目的:探究自由式滑雪空中技巧运动员躯干肌力与其专项成绩的关系,为国家队的训练和备战以及运动员选材提供理论依据。方法:应用ISOMED2000等动测试系统分别对自由式滑雪空中技巧国家队14名运动员进行60 /s、180 /s速度下躯干的屈伸力量和60 /s、150 /s速度下的躯干扭转力量进行测试,专项成绩通过国际雪联、中国滑雪协会以及跟队训练测试获得。结果:我国优秀自由式滑雪空中技巧运动员躯干屈伸肌群PT、PT/BW与空中技巧专项成绩呈正相关(r=0.59~0.83,P﹤0.05),且伸肌群的相关程度高于屈肌群。屈伸比值(F/E)与落地成功率呈负相关(60 /s r= -0.67, 180 /s r= -0.72, P﹤0.05)。躯干左右侧扭转肌力与专项成绩的相关程度在快速(150 /s)状态下高于慢速(60 /s)状态。在快速(150 /s)状态下,躯干左侧扭转肌力与专项成绩的相关程度高于右侧。左侧扭转肌群PT、PT/BW与落地成功率存在正相关(r=0.64、r=0.67,P﹤0.05)。结论:躯干屈伸肌力、扭转肌力对自由式滑雪空中技巧专项成绩影响非常关键,尤其是躯干伸肌群和躯干左侧扭转肌群的力量水平。
Objective: The study is aimed to provide theoretical basis for training and preparing for match and selection of 14 athletes of national team through exploring the relationship between specific performance and trunk muscle strength of freestyle skiing aerials athletes. Method: The research used ISOMED2000 isokinetic testing system to test national freestyle skiing aerials athletes performed 60 /s,180 /s speed trunk flexion and extension and 60 /s,150 /s speed trunk rotation. The relevant data of specific performance was obtained through FIS, Chinese Ski Association and training of national team. Result: The trunk flexion and extension PT, PT/BW of China excellent freestyle skiing aerials athletes have highly positive correlation with the specific performance(r=0.59~0.83,P﹤0.05).The correlation coefficient of trunk extension is higher than trunk flexion. F/E of trunk has negative correlation with the rate of landing success(60 /s r= -0.67, 180 /s r= -0.72, P﹤0.05). The correlation coefficient of trunk rotation at fast speed(150 /s)is higher than slow speed(60 /s).In fast speed, The correlation coefficient of left trunk rotation is higher than right and the left trunk rotation PT, PT/BW have positive correlation with the specific performance(r=0.64、r=0.67,P﹤0.05).Conclusion: The strength of trunk flexion and extension and trunk rotation has critical influence on the specific performance of freestyle skiing aerials, especially the trunk extension strength and left rotation strength.
