【摘要】：本文用录像观察法、图像解析法和数理统计为主要研究方法,对参加2013年第十二届全运会男子三级跳远比赛项目获得冠军的运动员曹硕为实验对象,研究对象为我国优秀三级跳远运动员曹硕的模拟训练。由于研究对象自身的情况和比赛日程的限制,使得两次的拍摄过程不易实施。本研究的两次拍摄过程均选取曹硕在国家体育总局训练局的田径馆模拟训练时最好的一次运动成绩,并依据前人研究结果的运动学参数为对照参数,对解析后的运动学技术参数应用运动生物力学原理和数学方法解析,并在我国优秀三级跳远运动员曹硕的平衡板结合专项体能训练前后分析出的跨步跳数据上进行对比分析。本研究发现我国优秀三级跳远运动员曹硕在平衡板结合专项体能训练前的模拟训练中的水平速度利用率较差,跨步跳各角度不是最佳的运动学角度,落地缓冲时间和蹬伸时间都要比世界优秀运动员长。分析讨论了跨步跳的起跳速度与起跳角度、跨步跳落地缓冲腿的支撑时间在平衡板结合专项体能训练前后数据上的差异性,以及曹硕在模拟训练中与世界优秀三级跳远运动员存在的差异,使其在今后的专项训练过程中应注意和加强的方面有了针对性的训练。并推断出平衡板结合专项体能训练对其跨步跳技术有影响的,并对于改善和提高其跨步跳技术是有帮助的。研究结论:我国男子三级跳远运动员曹硕在跨步跳起跳时的水平速度损失率偏高;跨步跳起跳技术的各角度参数与世界优秀三级跳远运动员存在着明显差异;其跨步跳过程中支撑总时间比世界优秀运动员要长。平衡板结合专项体能训练对于其跨步跳技术各运动学参数都有着影响,数值上都有相对的变化,都在向着世界优秀三级跳运动员的发展趋势发展,说明平衡板结合专项体能训练对我国运动员曹硕的跨步跳技术存在着有利的影响,对曹硕取得优异的运动成绩,起到了关键作用。
[Abstract]:Using video observation method, image analysis method and mathematical statistics as the main research methods, this paper takes Cao Shuo, an athlete who won the championship in the men's triple jump competition of the 12th National Games in 2013, as the experimental object. The object of study is the simulation training of Cao Shuo, an excellent triple jumper in China. Because of the limitation of the research object's own situation and the competition schedule, the two shooting process is not easy to carry out. The best performance of Cao Shuo in the track and field hall of the training Bureau of the State Administration of Sports was selected in the two shooting processes of this study, and according to the kinematics parameters of previous research results, the control parameters were taken as the control parameters. The kinematic technical parameters after analysis are analyzed by applying the principles of sports biomechanics and mathematical methods, and the step jump data obtained by Cao Shuo, an outstanding Chinese triple jumper before and after special physical training, are compared and analyzed. It is found that Cao Shuo, an excellent Chinese triple jumper, has a poor utilization ratio of horizontal velocity in the simulation training before the balance board combined with special physical training, and the angle of stride jump is not the best kinematics angle. Landing buffer time and pedaling time are longer than the world's best sports staff. This paper analyzes and discusses the difference of the take-off speed and take-off angle of the step jump and the support time of the buffer leg of the step jump ground between the balance board and the data before and after the special physical training. As well as the differences between Cao Shuo and the world's outstanding triple jumpers in the simulation training, the specific training should be paid attention to and strengthened in the course of the special training in the future. It is inferred that balance board combined with special physical training has influence on its step jump technique, and it is helpful to improve and improve its step jump technique. Conclusion: the loss rate of horizontal velocity of Chinese male triple jumper Cao Shuo is on the high side, and there are obvious differences between the angle parameters of step jump taking-off technique and the world's excellent triple jumpers. The total support time of the stride is longer than that of the world's elite athletes. The balance board combined with the special physical training has an impact on the kinematic parameters of its step jump technique, and has relative changes in the numerical value. All of them are developing towards the development trend of the world's outstanding triple jumpers. It is pointed out that the balance board combined with special physical training has a beneficial effect on Cao Shuo's step jumping technique and plays a key role in Cao Shuo's excellent performance in sports.
