【摘要】：目的:通多比较不同网球起动技术下的起动及短距离冲刺表现的差异性,进行起动技术的择优。方法:主要采用实验法。结果:向左侧移动时,各个起动技术在起动、2.5 m和5 m冲刺时间及起动和冲刺的总时间上差异性显著(偏η2=0.216~0.509,P0.001);向右侧移动时,各个起动技术在起动、2.5 m和5 m冲刺时间和起动及冲刺的总时间上差异性显著(偏η2=0.241~0.539,P0.001);前跨步和后撤步的起动和2.5 m的冲刺时间以及起动和2.5 m及5 m冲刺总时间有显著性差异(d=0.264~0.381,P0.05),且前跨步后撤步;两种向前起动技术的5 m冲刺时间没有显著性差异(P0.05)。结论:网球运动员在侧向移动时,采用支撑前移步的起动和短距离冲刺表现最佳,其次是重力步;随着冲刺距离的增加,这两种起动技术的作用要优于前冲步和并步。向前移动时,采用后撤步的起动和短距离冲刺表现最佳,随着冲刺距离的增加,这种起动技术的作用无异于前跨步。
[Abstract]:Objective: to compare the differences of starting and short distance sprints in different tennis starting techniques, and to select the best starting techniques. Methods: experimental method was used. Results: when moving to the left, there were significant differences in the starting time of 2.5 m and 5 m and the total time of starting and sprint (畏 _ 2: 0.216U _ (0.509) P _ (0.001), while moving to the right, there were significant differences in the starting time and the total time of starting and sprint. There were significant differences in the starting time of 2.5 m and 5 m and the total time of starting and sprint in each starting technology (畏 _ 2 / 0.241 / 0.539p _ 0.001m), the starting time of front step and backward step and 2.5 m sprint and the total time of starting and 2.5 m and 5 m sprint. There was significant difference (P 0.05) between 0.264 (0.384) and 0.381m (P0.05), and the former was striding forward and the other was retreating. There is no significant difference in 5 m sprint time between the two forward starting techniques (P 0.05). Conclusion: when tennis players are moving laterally, the starting and short distance sprint with the support forward step is the best, followed by gravity step, and the effect of these two starting techniques is better than that of forward step and parallel step with the increase of sprint distance. When moving forward, the starting and short distance sprint with backward step is the best. With the increase of sprint distance, the effect of this starting technique is no different from that of forward stride.
