| 摘 要： | 对国家队女子垒球6名优秀的投手进行三维定点拍摄和录像解析,实验结果表明国家队投手对投球动作整体掌握较熟悉,动作连贯性比较一致.在整个投球过程中的各投手投掷臂肩、肘、腕关节点的加速--制动都有一定的顺序性,且各关节点速度变化的规律基本相同;其中各投手完成投球动作的伸踏时间、伸踏距离、重心下降幅度、球出手速度、球出手高度等运动学指标已达国际一流水平.

| Abstract: | Fast pitch movement of 6 excellent women pitchers in China National Softball Team have been taken photograph by three-dimensional camera for kinematic analysis.The results indicate that excellent pitchers in the team have mastered the whole course of pitching with good continuity.The acceleration and deceleration of shoulder,elbow and wrist joints of throwing arm during pitching process indicate its order,and the rules of each joint's velocity changing are approximately similar.Among kinematical indexes in ... |
