本研究的目的是（1）评估运动员在休息和运动后的跑步成绩和副交感神经功能之间的关系，（2）检查在为期8周的跑步训练计划中心率（HR）衍生指数的变化。在14名中度训练的跑步者（36 +/-A7岁）中，每天测量静息迷走神经相关的心率变异性（HRV）指数，而运动HR和运动后HR恢复（HRR）和HRV指数每两周测量一次。在训练干预前后评估最大有氧速度（MAS）和10 km跑成绩。迷走神经相关指标的变化与MAS和10 km跑时间的变化呈显著相关（r > 0.60，P < 0.01）。运动心率在训练期间进行性降低（P < 0.01）。10 km跑时间降低> 0.5%的11名受试者（应答者），静息迷走神经相关指数呈进行性增加趋势（时间效应P = 0.03）和第7周期间可能和可能更高值的定性指标[+7%（90% CI -3.7 17. 0）]和第9周[+10%（90% CI -1.5 23）]与训练前值相比。运动后心率变异性显示出类似的变化，尽管组间差异不太明显。HRR在第3周显示出相对早期的可能下降[-20%（90% CI -42 10）]，仅在接近项目结束时略有下降。结果表明，休息，运动和运动后HR测量的潜力，评估和预测有氧训练对耐力跑性能的影响。
The aims of the present study were to (1) assess relationships between running performance and parasympathetic function both at rest and following exercise, and (2) examine changes in heart rate (HR)-derived indices throughout an 8-week period training program in runners. In 14 moderately trained runners (36 +/- A 7 years), resting vagal-related HR variability (HRV) indices were measured daily, while exercise HR and post-exercise HR recovery (HRR) and HRV indices were measured fortnightly. Maximal aerobic speed (MAS) and 10 km running performance were assessed before and after the training intervention. Correlations (r > 0.60, P < 0.01) were observed between changes in vagal-related indices and changes in MAS and 10 km running time. Exercise HR decreased progressively during the training period (P < 0.01). In the 11 subjects who lowered their 10 km running time > 0.5% (responders), resting vagal-related indices showed a progressively increasing trend (time effect P = 0.03) and qualitative indications of possibly and likely higher values during week 7 [+7% (90% CI -3.7;17.0)] and week 9 [+10% (90% CI -1.5;23)] compared with pre-training values, respectively. Post-exercise HRV showed similar changes, despite less pronounced between-group differences. HRR showed a relatively early possible decrease at week 3 [-20% (90% CI -42;10)], with only slight reductions near the end of the program. The results illustrate the potential of resting, exercise and post-exercise HR measurements for both assessing and predicting the impact of aerobic training on endurance running performance.
