The aim of the study was to investigate the influence of training load and exercise mode on heart rate variability and heart rate recovery (HRR) in healthy individuals. The subjects were divided into three groups: sedentary (SED), resistance trained (RT) and aerobically trained (RT). Resting and postmaximal exercise RR intervals were recorded on supine and seated position, respectively. The HRV indices calculated in the resting position were RMSSD and LF and HF power densities. The following HRR indices were calculated throughout the 5-minute postmaximal recovery period: semi-logarithmic regression analysis of the first 30 s (T30); absolute difference between the peak and 60 s HR (HRR(60s)); and mono-exponential time constant of HRR (HRRτ). The RMSSD on subsequent 30-s segments (RMSSD(30s)) on recovery period was also calculated. Both RT and AT groups presented faster HRR than SED (P<0·05). The aerobic trained group was the only group that presented vagal reactivation, when analysing the RMSSD(30s). There were no correlations between the Baecke sport score and the HRV vagal-related indices. However, it was significantly correlated with HRR. It was concluded that that the training load positively influences the HRR, but has no effect on the HRV at rest and that the type of exercise, showed a marked influence on HRV recovery.
本研究的目的是调查训练负荷和运动模式对健康个体心率变异性和心率恢复（HRR）的影响。受试者分为三组：久坐不动组（SED）、抗阻训练组（RT）和有氧训练组（AT）。分别在仰卧位和坐位记录静息和最大运动后的RR间期。在静息状态下计算的HRV指标为RMSSD以及低频和高频功率密度。在最大运动后5分钟的恢复期内计算以下HRR指标：前30秒的半对数回归分析（T30）；峰值心率与60秒时心率的绝对差值（HRR(60s)）；以及HRR的单指数时间常数（HRRτ）。还计算了恢复期后续30秒时间段的RMSSD（RMSSD(30s)）。RT组和AT组的HRR均比SED组快（P<0·05）。在分析RMSSD(30s)时，有氧训练组是唯一出现迷走神经再激活的组。Baecke运动评分与HRV迷走神经相关指标之间无相关性。然而，它与HRR显著相关。得出的结论是，训练负荷对HRR有积极影响，但对静息时的HRV没有影响，并且运动类型对HRV恢复有显著影响。
