通过对国家男子轮椅竞速队4×100m接力运动员接力每棒最佳起动时机的分析,以获取接力队员独立的每棒距离速度时间变化及相应的起动时间,用数值积分法计算最佳的接棒起动距离时机并和实际接力训练中的接棒起动距离时机进行比较。认为国家男子轮椅竞速队接力训练中出发距离偏小,启动时机过晚;根据最佳起动距离时机范围作接力测试时,交接棒可在前接力区完成,接力成绩有所提高。提出国家男子轮椅竞速队接力训练中要延长起动距离时机;计算的最佳出发起动时机可作为接力技术训练中起动距离时机设置的参考。
Through the analysis of the best starting timing of relay for each 4x100m relay athlete of national men’s wheelchair racing team in order to get the independent time variation of the speed and the corresponding starting time of relay for each relay club, the numerical integration method is used to calculate the optimal connection The starting distance of the stick is compared to the starting timing of the stick in the actual relay training. It is considered that the departure distance of national men’s wheelchair racing team during relay training is too small, and the starting time is too late. When the starting range of the best starting distance is used as the relay test, the handing over stick can be completed in the front relay zone and the relay performance improves. It is proposed that the starting distance should be prolonged in the relay training of the national men’s wheelchair racing team. The optimal starting timing of the calculation can be used as a reference for setting the starting distance in the relay training.
