【摘要】：研究目的:通过监测不同等级跆拳道运动员心率与心率变异性的变化特征来划分运动员的唤醒水平,进一步探究不同唤醒水平对跆拳道运动员运动决策能力的影响,进而为跆拳道运动员训练和比赛提供理论依据与实践指导。研究方法:本文选取了25名沈阳体育学院院队与跆拳道选修专业男子运动员作为实验对象,本研究主要采用实验法,以即时心算干预的方式来调控运动员的唤醒水平,利用生物反馈仪的心率监控装置为辅助手段,来监控运动员心率与心率变异性的变化情况,运用跆拳道运动决策测试程序对运动员的决策能力进行测量,进而探究不同唤醒水平对跆拳道运动员运动决策能力的影响。研究结果:1.被试内跆拳道运动员低唤醒水平与高唤醒水平相比较,运动员的运动决策准确性(p0.05),具有显著性差异。高水平运动员在高唤醒状态时的决策准确性要明显高于低唤醒水平。低水平运动员在低唤醒水平下的决策准确性要高于高唤醒水平。2.不同等级跆拳道运动员比较分析发现,高水平运动员的运动决策准确性明显高于低水平运动员(p0.01),具有显著性差异。3.不同运动水平运动员在不同唤醒水平下的运动决策准确性(p0.01),具有显著差异。高水平运动员在高唤醒水平下运动决策准确性要明显高于低水平运动员;在低唤醒水平下不存在显著差异性。4.不同等级跆拳道运动员在不同唤醒水平条件下的运动决策速度均不存在显著差异性,且交互作用不明显。但高水平运动员在不同条件下的运动决策速度要稍快于低水平运动员。研究结论:1.不同等级跆拳道运动员在不同唤醒条件下对运动决策准确性存在交互作用,高水平运动员在高唤醒水平下,运动决策准确性较高,自主神经系统交感神经活性较强,更有利于进入竞赛准备状态和进行决策加工;低水平运动员在高唤醒水平下,运动决策准确性较差,自主神经系统调节功能下降,更容易产生负性情绪;在低唤醒水平下,更有利于低水平运动员决策准确性的发挥,对高水平运动员影响不大。2.高水平跆拳道运动员运动决策速度稍快于低水平运动员,高水平运动员选择反应时快于低水平运动员,高水平运动员相对而言能更有效地选择性注意,对线索进行提前加工,对信息进行认知并做出反应。3.不同等级跆拳道运动员相比较而言,高水平运动员交感神经张力与副交感神经的协调能力较强。在高唤醒期LF/HF比值增加显著,而在基线期表示迷走神经张力的HF增高显著。
[Abstract]:Objective: to divide the arousal level of taekwondo athletes by monitoring the characteristics of heart rate and heart rate variability of taekwondo athletes, and to explore the influence of different arousal levels on taekwondo athletes' ability to make decisions. Then provide theoretical basis and practical guidance for taekwondo athletes training and competition. Research methods: this paper selected 25 male athletes of Shenyang Institute of physical Education and Taekwondo elective specialty as experimental objects. The arousal level of athletes was regulated by the intervention of immediate mental arithmetic, and the heart rate monitoring device of biofeedback instrument was used as a supplementary means to monitor the changes of heart rate and heart rate variability of athletes. Using the Taekwondo exercise decision testing program to measure the athletes' decision-making ability, Then the paper explores the influence of different arousal levels on the decision making ability of taekwondo athletes. The result of the study is: 1. The low arousal level of taekwondo athletes is compared with the high arousal level of taekwondo athletes. The decision accuracy of athletes in high level athletes is higher than that in low arousal level, and the decision accuracy of low level athletes should be higher than that of low arousal level, and the decision accuracy of low level athletes should be higher than that of low arousal level. Higher than the high arousal level. 2. The comparative analysis of taekwondo athletes of different grades found that, The accuracy of sports decision making of high level athletes is obviously higher than that of low level athletes, which has significant difference. 3. The accuracy of sports decision making of athletes at different levels of arousal is significantly different from that of high level athletes under different arousal levels. Under the condition of high arousal level, the accuracy of sports decision making is obviously higher than that of low level athletes. There is no significant difference under the low arousal level. 4. There is no significant difference in the speed of decision making of taekwondo athletes of different grades under different arousal level. The interaction is not obvious, but the decision speed of high level athletes is a little faster than that of low level athletes under different conditions. Conclusion: 1. Taekwondo athletes of different grades are accurate in sports decision under different arousal conditions. Sexual interaction, Under the condition of high arousal level, the accuracy of sports decision is higher, and the sympathetic nerve activity of autonomic nervous system is stronger, which is more advantageous to enter the state of competition preparation and decision processing, while the low level athlete is in the high arousal level. The poor accuracy of sports decision making, the decline of autonomic nervous system regulation function, the lower arousal level, the lower level of arousal, are more helpful for the lower level athletes to play the role of decision accuracy. The decision speed of high level taekwondo athletes is a little faster than that of low level athletes, and the reaction time of high level athletes is faster than that of low level athletes. High-level athletes are relatively more effective in selective attention, processing clues ahead of time, recognizing information and responding to it .3.Compared with taekwondo athletes of different grades, The ability of coordination between sympathetic tension and parasympathetic nerve in high level athletes was stronger, the ratio of LF/HF increased significantly in high arousal stage, and HF, which indicated vagal tension in baseline stage, increased significantly.
