摘　　要：运用图像采集与解析方法对王宇在第12届全运会男子跳高决赛中越过2.29m一跳的腾空过杆技术进行了三维运动学解析研究。结果表明:王宇在起跳结束瞬间,摆动腿的摆动比较积极主动;腾起角与身体重心过杆夹角比较合理;腾空过杆阶段身体重心的轨迹最高点不在横杆的正上方,没有最大限度地利用H2的高度;王宇的H3值略接近于世界优秀运动员的H3值;髋轴与横杆的夹角较小,背弓充分。By using the methods of image collection and analysis,the paper conducts a three dimensional kinematic research on Wang Yu’s success in clearing 2. 29m in men＆#39;s high jump finals at the Twelfth National Games. The results show that Wang Yu’s swinging leg is active at take - off with reasonable take - off and clearing in-cluded angle. His body center of gravity is not vertical to the bar when clearing,failing to take a full advantage of the height of H2. Wang’s H3 value is close to that of the world elite high jumpers. His hip axis and included angle are smaller with full bow of the back full.
