自由式滑雪空中技巧运动员姿势控制训练及效果评价研究

Research on Posture Control Training and Effect Evaluation of Freestyle Skiing Aerials

目的:对我国自由式滑雪空中技巧队运动员姿势控制能力进行训练和评价,为后期的专项训练实践提供指导和参考。方法:对13名国家运动员(男性6名,女性7名)进行3种不同的姿势控制能力训练,利用METITUR平衡能力测试系统在训练前后对13名国家运动员进行平衡能力测试,一个训练周期后,对2017年和2018年两个赛季运动员的技术动作进行对比分析。结果:通过METITUR平衡能力测试,13名运动员静态平衡能力在前后方向上(Y轴向)的稳定性升高,说明运动员在控制重心能力上有所提高。通过训练前后运动员的动态平衡能力测试人体重心曲线图,运动员训练后在支撑面左右方向的自动态平衡能力有所有提高。技术动作对比分析的结果显示,运动员的着陆成功率也有了较大幅度的提高。结论:通过为期6个月的姿势控制能力的训练,运动员的静态平衡能力在支撑面前后方向上明显提高,动态平衡能力在支撑面后的左右方向上有显著提升。

Objective: To train and evaluate the posture control ability of Chinese freestyle skiing aerials team, so as to provide reference for the future training. Methods: 13 national athletes(6 males and 7 females) were trained with three different postural control abilities. Before and after the training, the balance abilities of the 13 subjects were tested with METITUR balance ability test system. After a training cycle, the technical movements of the athletes in 2017 and 2018 seasons were compared and analyzed. Results: Through the METITUR balance test, 13 athletes showed an increase in static balance stability in the front-rear direction(Y-axis), indicating an improvement in the ability to control the center of gravity. According to the body weight center curve of the athletes’ dynamic balance ability before and after the training, their self-dynamic balance ability in the left-right direction improved after training. The comparative analyses of the technical movements show that the landing success rate of the athletes has also been greatly improved. Conclusion: After6 months of postural control training, the static balance ability of the athletes was significantly improved in the front-rear direction, and the dynamic balance ability was significantly improved in the left-right direction.
