对推铅球沿步技术速度节奏的探讨

以我国现役优秀女子铅球运动员推铅球滑步技术的速度节奏为着重点，分析、研究滑步阶段蹬摆动作、身体重心和铅球的速度变化对滑步技术速度节奏的影响。指出我国优秀女子铅球运动员滑步阶段的蹬摆技术不够完善，铅球最高和重心最高速度差值大，从而影响到滑步过程中人体的移动及过渡步和最佳投前姿势的形成。认为我国优秀女子运动员的滑步技术需加以改进。

Research on the Speed Change in Coule Technique of Pushing Lead Balls

With emphasis on the speed change in coule technique used by excellent modern Chinese women service athletes in pushing lead balls, the analysis and study are made on the influence of the movements of treading and swinging, the change of gravitational center of the body and speed of lead ball on the speed change of coule technique. It is indicated that their coule technique is not perfect because of the large difference between the maximum speed of lead ball and that of the gravitational center of the body, which hinders the shift of the body and the formation of transitional pace as well as the optimum posture before pushing during the process of coule, so that it is necessary for the athletes to improve their coule technique.
