背景:心率变异分析(HRV)是测量高水平运动员周期训练负荷安排和减量训练过程中心脏自主神经系统波动的一种简单、无创的测量方法。本研究包括3个案例分析,目的是检测残奥会游泳冠军日常心脏自主神经波动的变化。方法:在残奥会之前的17周每天监测3名残奥会游泳冠军的静息HRV。在特定的时间和频率区域测试,并伴HRV非线性指标计算进行分析。所有HRV数据用每日值进行单独分析,用周平均值进行分析以及静息时相和训练时相均值进行分析。结果:在整个监测阶段,3名运动员(截肢运动员)所有的HRV参数均存在显著性差异。结论:在运动员监测过程中,尽管长期改变非常微小,游泳分类和残疾类型都能明显影响HRV。关于影响残疾运动员对训练、旅行和其他外界因素的个体反应进一步理解,可能会提高对增强运动表现运动负荷的管理和监控。
Background: Heart rate variability analysis (HRV) is a simple, noninvasive method of measuring cardiac autonomic nervous system fluctuations during high-level athletes’ cycle training load and weight reduction training. This study includes three case studies aimed at detecting changes in the spontaneous cardiac fluctuations of the daily heart of the Paralympic Swimming Champion. Methods: The resting HRV of 3 Paralympic Swimming Champions was monitored daily for 17 weeks prior to the Paralympic Games. In a specific time and frequency region test, and with non-linear HRV calculation for analysis. All HRV data were analyzed individually using daily values, analyzed with the weekly average, and the resting phase and training phase average. Results: All HRV parameters of 3 athletes (amputees) were significantly different throughout the monitoring period. Conclusion: In the monitoring process of athletes, although the long-term changes are very small, the classification of swimming and disability types can significantly affect the HRV. Further understanding of the individual responses that affect disabled athletes on training, travel, and other external factors may improve the management and monitoring of exercise load that enhances performance.
