This study examines whether heart rate recovery (HRR) improves as a result of exercise training during cardiac rehabilitation (CR).
A retrospective study was performed that included 100 patients who completed phase II CR and had entry and exit exercise stress tests. HRR was compared for the sample. Improvements in HRR were compared between gender and age groups. Correlation between age and HRR was performed.
The total sample improved HRR (P = .020). There was no significant difference in the improvement of HRR based on gender, indicating males and females improve at similar rates (P = .833). Similarly, there was no significant difference in the improvement of HRR based on age, indicating older subjects improve similarly to younger subjects (P = .700). There was no relationship between age and HRR; therefore, as age increases there is no decrease in HRR.
HRR improves in patients who complete CR.
本研究旨在探讨心脏康复（CR）期间运动训练是否能改善心率恢复（HRR）。
进行了一项回顾性研究，纳入了100名完成II期CR且进行了运动应激试验的患者。对样本的HRR进行了比较。比较了不同性别和年龄组HRR的改善情况。对年龄与HRR进行了相关性分析。
总体样本的HRR有所改善（P = 0.020）。基于性别的HRR改善情况无显著差异，表明男性和女性的改善率相似（P = 0.833）。同样，基于年龄的HRR改善情况也无显著差异，表明老年受试者与年轻受试者的改善情况相似（P = 0.700）。年龄与HRR之间无关联；因此，随着年龄增长，HRR不会降低。
完成CR的患者的HRR有所改善。
