应用心率变异性指标评价优秀耐力运动员机能状态研究进展

Heart Rate Variability and the Assessment of Elite Endurance Athlete

心率变异性(Heart Rate Variability,HRV)分析是监测个体训练适应性的无创伤便捷方法。HRV数据反映的副交感神经活性可以提示机体对耐力运动的消极或积极适应性信息。然而,该领域的研究对象多数是普通运动人群,优秀运动员较少,并且,HRV数据采集方法、指标选择及评价标准相对不统一。目前,可靠性较高的分析指标R-R间期差值均方根的自然对数(Ln rMSSD)被应用于评价优秀耐力运动员的运动能力及疲劳反应,且多日Ln rMSSD均值被用来解释如何纵向理解个体HRV基本图谱。

Measures of heart rate variability（HRV）are often considered a convenient non-invasive assessment tool for monitoring fatigue and fitness,which was direct implication for adjusting individual adaptation to training.However,much of the research in changes of HRV has involved recreational and amateur athletes,with few studies conducted in elite athletes.Additionally,it is important to be focus on the inaccuracy of the acquisition of HRV data and the selection of index.The natural logarithm of the square root of the mean sum of the squared differences between R-R intervals（Ln rMSSD）was preferred to assess the performance and the fatigue in elite athletes,which showing how these indices can be practically applied to explain the basic figures of the individual one.
