主要采用高速摄影与运动录像解析法与实验法,对四川成都九名女子100米栏运动员8周的核心力量训练,通过训练前后对比分析研究发现：运动员身体素质与核心稳定能力水平有显著性提高,特别是髋关节灵活性及核心稳定性有非常显著性提高;运动员身体重心在栏上的运动轨迹有明显变化,主要表现为身体重心垂直投影点与栏的水平距离缩小,身体重心与栏的垂直距离变小,躯干前倾角变小,身体重心在垂直方向的位移变小;运动员对个人体能水平的控制能力有一定程度的提高,这主要表现在个人技术水平与现有体能水平的合理分配,也就是个人体能能力向技术水平提高的正迁移比例增加,起跨技术也有明显提高,着地技术虽有所改善但还有待于提高。

With the methods of high-speed photography,video analysis and experiment,the paper made a comparative analysis of 9 women＇s 100m hurdles athletes from Chengdu and Sichuan before and after the core strength training.After training,there was significant improvement in athletes＇ physical fitness and core stability,especially in the hip flexibility and core stability.There are obvious changes in the movement orbit of gravity centre,including the smaller horizontal and vertical distance between vertical projection of gravity center and hurdle,smaller trunk anteversion and vertical displacement of gravity centre.The athletes had better ability in controlling personal fitness,which is manifested in reasonable allocation of individual skill level and physical strength as well as the improved skill in taking off and landing.
