中文摘要:
      以上海市蹦床队5名一线男子运动员为研究对象,通过视频与足底压力同步测试的研究方法,对蹦床运动员的预跳和5个基本的技术动作进行测试,研究男子蹦床运动员在完成不同基本技术动作过程中足底压力的分布的特征及足底压力分布的一般规律。为蹦床运动员进行科学训练提供理论依据,为蹦床运动员运动技术诊断提供客观指标。研究结论:运动员完成不同基本技术动作足底压力分布特征规律相同,足底压力合力变化、压强峰值分布和压力中心变化无显著性差异。触网起跳过程双足压力合力呈单峰曲线网面达最低点时双足压力合力最大,双足压力合力最大值可达体重的3.04倍。压强峰值表现为双足第五趾骨区较高。运动员在起网蹬伸阶段双足呈现出压力中心偏移现象,与运动员起跳过程中双足用力不均有关。
英文摘要:
      Taking the 5 Shanghai professional trampoline athletes as the subjects and using the method of synchronous test of video and plantar pressure, the author made a test during the athletes' pre-jump and 5 basic technical movements in order to study the characteristics and the general rule of the plantar pressure distribution when the male trampoline athletes complete different technical movements. The aim is to provide theoretical base for athletes' scientific training and the objective indicators for the technical diagnosis of trampoline athletes. The result shows that the characteristics and general rule of the plantar pressure distribution are the same when athletes complete different basic technical movements. There is no significant difference between the changes of plantar pressure resultant forces, pressure peak distribution and the changes of pressure center. During the process of touching net, the maximum feet pressure resultant force is observed when the force has a single-peak curve and the net reaches the lowest point. The maximum value of the feet pressure resultant force can be 3.04 times the weight. The peak pressure can be detected at the 5th toe phalanges. The offset of the pressure center of the athletes' feet during the push-off phase is due to the uneven force of the athlete's feet.
