【摘要】：实验目的:本研究旨在通过不同重量药球在网球运动员训练前准备活动时进行侧抛练习,试图探究网球运动员正手击球激活效应的最佳药球重量,以及最佳激活效应的延迟性时间点。为网球赛前和训练前准备活动提供实践性建议。实验方法:本实验选取10名北京体育大学网球专项班的国家二级网球运动员,在基本准备活动后进行1组6次的不同重量(6磅、8磅、10磅)药球侧抛练习,然后分别在即刻、15分钟和30分钟三个时间点,测试击球的挥拍速度和侧抛药球的爆发力,观察不同重量药球和不同时间点肌肉的最佳激活效应。结果:研究一:被试者在药球侧抛练习前的挥拍速度为62.5m/s,通过6磅、8磅、10磅药球侧抛训练后的挥拍速度分别为63.50m/s、65.90m/s、63.80m/s。侧抛练习后的挥拍速度显著高于药球侧抛训练前的挥拍速度且8磅药球侧抛练习后的挥拍速度最大。3种重量药球侧抛练习后即刻、15分钟、30分钟三个不同时间点挥拍速度具有显著性差异,其中8磅药球侧抛练习后的15分钟时间点的挥拍速度最大。研究二:被试者用6磅、8磅、10磅药球进行侧抛练习时的爆发力分别为2118.3w、3012.5w、2380.5w,不同重量药球侧抛时的爆发力与对应重量药球侧抛练习后的挥拍速度的相关系数为0.435、0.398、0.412。结论:网球运动员训练前专项热身可以用8磅药球(约为5%BW)进行训练前激活,在训练开始前15分钟时进行训练激活效果最佳。提高网球运动员的旋转爆发力可以有效提高网球运动员正手挥拍速度。
[Abstract]:Objective: the purpose of this study was to investigate the best weight of the ball in tennis players' forehand batting activation effect by using different weights of medicine balls to carry out side throwing exercises before the tennis players' training.And the delay time point of the optimal activation effect.Provide practical advice for pre-tennis and pre-training preparation activities.Methods: ten national secondary tennis players in the tennis special class of Beijing University of physical Education were selected to carry out 6 different weight 6 pounds / 8 lb / 10 lb) side throwing exercises after basic preparatory activities.Then, at 15 minutes and 30 minutes respectively, the batting speed and the explosive force of the pellet were measured, and the best activation effect of muscle was observed at different weight and different time points.Results: in the first study, the swinging speed of the subjects was 62.5 m / s before practice, and 63.50 m / s / s of 65.90 m / s / s + 63.80 msrespectively after 6 lbs / 8 lb / 10 lb / lb / g / lb / g / lb / g.The swing speed after side throwing practice was significantly higher than that before the medicine ball side throwing training, and the maximum swing speed after 8 pounds side throwing exercise was 3. 3 kinds of weight ball side throwing exercises, immediately after 15 minutes, 30 minutes, three different time points of swing.There was significant difference in the beat speed.The 8-pound pellet swing was the fastest at 15 minutes after practice.In the second study, the detonation force of 6 lb / 8 lb / 10 lb pellets was 2118.3 wW / 3012.5wW / 2380.5 ws, respectively. The correlation coefficient between the detonation force and the swing velocity of the pellets with different weights was 0.4350.3980.412w.Conclusion: the special warm-up of tennis players before training can be activated with 8-pound medicine ball (about 5BW) before training, and the best effect is to activate it 15 minutes before the start of training.Improving tennis player's rotating explosive force can effectively improve the tennis player's forehand swing speed.
