背景:有关障碍赛的研究很少,其中大部分研究主要针对跨越障碍物时如何保持跑步速度的生物力学因素。但关于生物力学因素和跨越障碍的经济性的关系尚无深入研究。本研究旨在探索障碍赛过程中,运动成绩和生物力学变量与跨栏效率的关联性。方法:本研究分别测量在有障碍与无障碍的情况下,大学生运动员和职业障碍赛运动员的跑步效率,以及跑步速度、起跳距离、离地高度和膝关节伸角度的生物力学指标;同时,障碍赛成绩会被用来和有无障碍物时的跑步经济性比率做相关性分析。结果:在每圈5个障碍的情况下,当耗氧量提高2.6%时,障碍赛的成绩和有无障碍下的经济性比率没有相关性。同时,上述生物力学变量和经济性比率之间无相关性。结论:障碍赛中提高跑步速度并不影响跑步效率。提高跑步速度有利于保持比赛节奏,且不会影响动作的经济性。
Background: There are very few studies on obstacle games, and most of the research focuses on the biomechanical aspects of how to maintain running speed while crossing obstacles. However, there is no further study on the relationship between biomechanical factors and the economics of obstacle crossing. The purpose of this study was to explore the relevance of motor performance and biomechanical variables to hurdle efficiency during the Obstacle Course. Methods: The present study measured the running efficiency of college athletes and obstacle racers, as well as the biomechanical parameters of running speed, take-off distance, ground clearance and knee extensor angles in the presence and absence of obstacles. At the same time, the obstacles Results will be used to determine whether there is a barrier-free run economy ratio to make a correlation analysis. Results: When the oxygen consumption increased by 2.6% with 5 obstacles per lap, there was no correlation between the performance of the obstacle course and the accessibility rate under the economy. At the same time, there is no correlation between the above biomechanical variables and the economic ratio. Conclusion: Improving the running speed in the obstacle course does not affect the running efficiency. Raising the running speed helps keep the pace of the game without compromising the economy of the action.
