三维数字测力铅球的研制及应用

介绍了三维数字测力铅球研制的设计思想、主要结构、功能及技术参数，并结合录像对实际测量结果进行分析与评价。采用的仪器是目前使用较为广泛的单片机微电脑处理系统和成熟的压力传感技术，通过和专项器械铅球相结合，实现了对实际运动中肢体游离端动态力的测量，能够快速、便捷、准确地反馈运动员在整个投掷过程中的用力特点，可以协助教练员对运动员进行技术诊断，制定科学的训练计划。

Three Dimensional Force Testing Application to the Shot Put

The paper investigates the shot put using the three dimension force testing instrument to analyse and evaluate the movement image. This system adopts the mature pressure sensor technique and uses the relatively wideranging microcomputer processing system. The dynamic force measurement of limb tip extremity during the actual movement was measured indicating that software process system is comparatively richer. It can speedily and conveniently feedback the exertion features of athletes during the entire throwing process. It may help the coach to diagnose the athlete's technique and draw up a scientific training program.
