| 中文摘要: |
| 跳远和三级跳远均属于典型的速度力量型远度项目。采用文献资料、专家访谈、测试法和数理统计等研究方法,通过对我国优秀男子跳远和三级跳远运动员的助跑最后一步的某些运动学参数进行对比研究，结果表明：（1）助跑最后一步摆动腿支撑阶段的身体重心高度变化值，跳远组比三级跳远组大且具有显著性差异。（2）助跑最后一步的最大缓冲瞬间，跳远组的摆动腿大腿角速度比三级跳远组大，且具有显著性差异。（3）助跑最后一步支撑阶段摆动腿缓冲扇角和蹬伸扇角，三级跳远组均大于跳远组。 |
| 英文摘要: |
| Long jump and triple jump belong to typical speed strength sports. By the methods of literature study, expert interview, test and statistics, the article makes a comparative study of some kinematic parameters of the last run-up step of the China’s elite long jump and triple jump athletes. The result shows the following?1)The height changing values of the body center of gravity of the swinging leg in the supporting phase of the last run-up step of the long jump group are greater than those of the triple jump group and are significantly different. (2)In the maximum buffering moment of the last run-up step, the thigh angular velocity of the swinging leg of the long jump group is greater than that of the triple jump group.(3)The swinging leg buffer fan angle and stretching fan angle in the supporting phase of the last run-up step of the triple jump group are greater then those of the long jump group. |
