研究目的：分析我国三名女子竞走10 km运动员运动技术的特征，了解我国目前竞走技术水平，为我国竞走女子10 km运动员提高和改善技术提供运动学参数依据。研究方法：采用一台SONY EX-FH25摄像机对比赛进行平面定点定标摄像。使用德国Simi mo-tion运动图像解析软件对我国三名运动员竞走一个复步的动作视频录像进行运动学指标解析。研究结果发现我国女子10 km竞走运动员存在以下技术特征和问题：1)在影响腾空判罚类指标中，我国运动员的腾空时间控制的较好，但实效性不好，主要表现为头顶点和重心垂直起伏较大，容易被裁判员判罚；2)我国三名运动员极少出现屈腿犯规，尤其是“反弓”获得了很好的视觉表象；3)中国运动员“小步高频”的技术风格有所改变，步幅提高，但步频存在的差异；4)中国女子运动员踝关节蹬伸幅度偏小，且存在左、右腿力量分配不均衡现象。研究结论是我国女子10 km运动员应保持合理腾空时间，减小身体上下起伏幅度。建议我国女子10 km竞走运动员固定合理稳定步长和加快步频，提高踝关节蹬伸幅度。

Research purposes:Analysis of characteristics of China Three Women Walking Race Athletes 10 km technology ,understanding of race walking technology level in our country at present,kinematic parameters provide a basisfor our women’ s 10 km Race Walking Athletes en-hance and improve technology. Research methods:Use a SONY EX-FH25 camera on the game point calibration im-aging plane. Use German Simi Motion motion imagea naly-sis software for a complex of three Walkers step action video kinematic indicators resolve. The results have iden-tified the following technical characteristics and Problems of Women 10 km Race Walkers:1 ) The impact category indicators penalty vacated, the flight time better control our athletes,but effectiveness is not good,the head point and the center of gravity vertical undulating,easy to refer-ee foul. 2)China three players foul rarely occurs with bent knees,especially the“anti-bow”to get a good visual repre-sentation. 3) Chinese athlete “small step high frequency”technical style has changed,The pace of increase,but the difference on the frequency. 4 ) Chinese women athletes ankle kicking amplitude is small, and there are left and right leg power distribution imbalances. Our study con-cludes that women’s 10 km athletes should maintain a rea-sonable flight time, reduce the ups and downs of the body. Suggestions on Women’s 10km Race Walkers rea-sonably stable fixed step size and speed up the stride fre-quency,amplitude increase kicking ankle.
