Abstract

Purpose: Previous studies have shown delayed cardiac vagal reactivation after high-intensity endurance exercise when estimated with heart rate variability (HRV). However, the recovery dynamics of RR intervals (RRI) and HRV after a maximal incremental exercise test have been studied less in non-athletic population and especially in females. The main aim of the study was to examine the recovery dynamics of RRI and HRV immediately after a maximal cardiopulmonary exercise test (CPET) in adult females.

Methods: Twenty-eight healthy, novice recreational female runners (33.7 ± 4.2 years) were selected to participate in this study from a larger group of participants (Run RCT). RRIs were collected continuously during a controlled rest, a CPET on a treadmill and a 15-min controlled, passive recovery. Minute-by-minute recovery dynamics were analyzed.

Results: The dynamic phase of RRI and heart rate recovery (HRR) (from 192.2 ± 9.9 to 111.4 ± 2.4, P < 0.001) occurred during the first 4.5 min with HRR of 36 ± 10 beats during the first minute of the recovery. Resting heart rate was negatively associated (r = - 0.53, P = 0.016) with HRR during the recovery. No recovery of root mean square of successive RRIs (RMSSD) was detected during the 15-min recovery. RMSSD was 15.0 ± 9.2% of resting values at the end of the recovery.

Conclusion: No recovery of vagal-derived HRV was detected immediately after a CPET in novice recreational female runners despite marked changes in sympathovagal balance, detected by rapid recovery of RRI during the first 5 min after exercise cessation.

女性跑步新手在最大心肺运动测试后心率和心率变异性的恢复情况。

目的：以往的研究表明，根据心率变异性（HRV）估计，高强度耐力运动后心脏迷走神经的再激活会出现延迟。然而，关于最大增量运动测试后 RR 间期（RRI）和心率变异性的恢复动态，在非运动人群尤其是女性中研究较少。本研究的主要目的是研究成年女性在最大心肺运动测试（CPET）后RRI和心率变异的恢复动态：从一个更大的参与者群体（Run RCT）中挑选了 28 名健康的休闲跑步新手女性（33.7 ± 4.2 岁）参与本研究。在受控休息、跑步机上的 CPET 和 15 分钟受控被动恢复期间连续收集 RRI。对每分钟的恢复动态进行了分析：结果：RRI 和心率恢复（HRR）的动态阶段（从 192.2 ± 9.9 到 111.4 ± 2.4，P 结论：RRI 和心率恢复（HRR）的动态阶段没有恢复：尽管交感-迷走平衡发生了显著变化，但在 CPET 结束后的最初 5 分钟内，通过 RRI 的快速恢复可以检测到迷走源性心率变异，而在新手休闲女性跑步者中，CPET 结束后并未立即检测到迷走源性心率变异的恢复。

期刊介绍： The European Journal of Applied Physiology (EJAP) aims to promote mechanistic advances in human integrative and translational physiology. Physiology is viewed broadly, having overlapping context with related disciplines such as biomechanics, biochemistry, endocrinology, ergonomics, immunology, motor control, and nutrition. EJAP welcomes studies dealing with physical exercise, training and performance. Studies addressing physiological mechanisms are preferred over descriptive studies. Papers dealing with animal models or pathophysiological conditions are not excluded from consideration, but must be clearly relevant to human physiology.
