| 中文摘要: |
| 采用图像解析的方法对郭佳浩“侧手翻接屈体后空翻两周半”技术动作进行运动学分析研究。研究表明，郭佳浩助跑速度快；上板踏跳快速有力，垂直速度增加较高；撑马时间短促有力；第二腾空横轴和纵轴转体角速度快，空中姿态保持较好，落地较稳；第二腾空时间长，腾空高度高；不足之处在于他触马瞬间到离马瞬间过程中垂直速度有所减小。 |
| 英文摘要: |
| The authors made a kinematic analysis of Guo Jiahao's movement of "cartwheel and two-and-a-half twist back somersault" by video analysis. The advantages of his movement lie in high approach speed, quick powerful board treading, high vertical speed in taking-off, rapid powerful support on horse, high angular speed both in abscissa and ordinate axes and holding posture in the second flight, stable landing, long flying time and great height in the second flight. His shortcoming lies in decreased vertical speed from touching the horse to taking off. |
