【摘要】：研究目的：测量北京体育大学二级网球运动员与一般网球运动员在正手击球条件下大脑的专注度和放松度水平,分析二级网球运动员与一般网球运动员之间在正手击球时的专注度和放松度的差异,并探讨专注度与放松度水平对网球专项学生正手击球得分的影响,从理论上为教练员了解网球运动员正手击球训练状况提供参考,为今后的训练提供科学的理论依据。方法：以20名北京体育大学网球专项学生为研究对象,分别为二级运动员10人,与一般运动员10人,共计20人,利用circlet测试分析系统对二级运动员与一般运动员进行正手击球时的专注度与放松度的测试。实验过程：测试者在安静状态下测试5分钟,分别记录安静状态下的专注度和放松度的分值。在正手技术测试中,由固定一人喂球,每一位测试者正手击球直线和斜线分别为10组,每一组6个球,共计为正手直线击球60个球、斜线60个球,共计120个球,其中,按照ITN计分方法,固定一人根据击中相应区域记录得分成绩,将每组得分为32分以上为高分组(HSG),得分17分以下为低分组(LSG),标记每个球,记录击球得分。研究结果：(1)二级运动员击球得分时的专注度水平与一般运动的专注度对比为(65.59±6.29 VS 60.79±7.92)没有显著性差异,二级运动员正手击球得分的放松度与一般运动员的放松度之间的对比为(70.80±3.56 VS65.09±4.75)有显著性差异(p0.05)；(2)二级运动员在正手击球得分为高分的时候的专注度与一般运动员高分时的专注度对比没有显著性差异(p0.05),放松度也没有显著性差异(p0.05)；(3)两者正手击球为低分的时候的专注度与没有显著性差异(p0.05),放松度也未见明显差异性(p0.05)。研究结论：(1)在正手击球中,二级组比一般组在击球时具有更高的放松度,说明运动水平的提高与放松度有统计学意义,与专注度没有统计学意义。(2)在正手击球中,网球运动员的放松度对正手击球得分是有影响的。
[Abstract]:Objective: to measure the brain concentration and relaxation of the second class tennis player and the general tennis player in Beijing University of physical Education under the condition of forehand stroke. This paper analyzes the difference of the concentration and relaxation between the secondary tennis player and the general tennis player when hitting forehand, and probes into the influence of the level of concentration and relaxation on the score of forehand batting of tennis special students. It provides a reference for coaches to understand tennis players forehand batting training condition and provides scientific theoretical basis for future training. Methods: a total of 20 tennis students from Beijing physical Education University were studied, including 10 second-class athletes and 10 ordinary athletes. The circlet test analysis system was used to test the concentration and relaxation of forehand batting between the second class player and the general player. The experiment process: the testers were tested in quiet state for 5 minutes and recorded the scores of concentration and relaxation in quiet state respectively. In the forehand technique test, the ball was fed by one fixed person. Each tester had 10 batting lines and a diagonal line, each with 6 balls in each group, with a total of 60 shots in the forehand line and 60 bevel balls, a total of 120 balls. According to the ITN scoring method, one fixed person recorded the score according to the corresponding hit area, and each group scored more than 32 points for the high score group, and the (HSG), score below 17 points for the lower group (LSG), mark each ball, and recorded the hit score. The results were as follows: (1) there was no significant difference in the level of concentration between the second class athletes and the general sports players when they hit the ball (65.59 卤6.29 VS, 60.79 卤7.92). There was a significant difference between the relaxation degree of forehand batting score and the relaxation degree of general athletes (70.80 卤3.56 VS65.09 卤4.75). (2) there was no significant difference (p0.05) and no significant difference (p0.05) between the second class athletes when the forehand batting score was high and the average player when the score was high. (2) there was no significant difference in the degree of relaxation between the two players when the forehand score was high (p0.05), and there was no significant difference between the two groups (p0.05). (3) there was no significant difference between the two groups when forehand batting was low (p0.05), and there was no significant difference in relaxation (p0.05). The conclusions are as follows: (1) in forehand batting, the second group has a higher degree of relaxation than the general group, indicating that the improvement and relaxation of sports level is statistically significant, and there is no statistical significance with the degree of focus. (2) in forehand batting, there is no statistical significance between the two groups. The relaxation of a tennis player has an effect on the forehand score.
