Measuring heart rate recovery (HRR) holds valuable cardiovascular information and requires minimal technical skill and cost. Understanding the associations between HRR and more robust cardiovascular indicators, such as central systolic blood pressure (CSBP), can provide valuable cardiovascular information with less involvement. CSBP is a strong predictor of certain cardiovascular diseases. The study aims to examine the association between measures of HRR and CSBP and the augmentation index (AIx) in a group of young, healthy individuals and based on sex.
One-hundred and seven participants (men - 55, women - 52) were measured for HRR at one minute (HRR) and two minutes (HRR) after maximum oxygen consumption (VO) testing, CSBP, and the AIx at a heart rate of 75 beats∙min (AIx@75).
The Pearson correlation indicated no association between HRR, HRR, and CSBP in men and women combined: r = 0.06, P = 0.53; r = 0.05, P = 0.59, respectively, or based on sex: men = r = 0.01, P = 0.95; r = 0.04, P = 0.79, respectively, and women = r = -0.05, P = 0.75; r = -0.09, P = 0.52, respectively. However, there were associations between HRR and AIx@75 in men and women combined: r = -0.37, P < 0.001, and based on sex: men = r = -0.31, P = 0.02, and women = r = -0.38, P < 0.01.
Measures of HRR were not associated with CSBP in a combined group of young men and women or based on sex. Most measures of HRR, especially those established by parasympathetic nervous activity, were associated with lower AIx@75. Though measures of HRR might be good indicators of cardiovascular disease, they might not be good indicators of CSBP in young, healthy individuals.
心率恢复（HRR）的测量具有有价值的心血管信息，并且需要最少的技术技能和成本。了解 HRR 与更强大的心血管指标（如中心收缩压（CSBP））之间的关联，可以提供有价值的心血管信息，而涉及的内容较少。CSBP 是某些心血管疾病的强有力预测指标。本研究旨在检查一组年轻健康个体中 HRR 与 CSBP 和 AIx（在心率为 75 次/分时的 AIx@75）之间的关联，并根据性别进行分析。
对 107 名参与者（男性 55 名，女性 52 名）进行了最大摄氧量（VO）测试后一分钟（HRR）和两分钟（HRR）的 HRR 测量、CSBP 和心率为 75 次/分的 AIx@75 的测量。
Pearson 相关性分析表明，男女混合组的 HRR、HRR 和 CSBP 之间没有关联：r = 0.06，P = 0.53；r = 0.05，P = 0.59，或者按性别分类：男性 r = 0.01，P = 0.95；r = 0.04，P = 0.79，女性 r = -0.05，P = 0.75；r = -0.09，P = 0.52。然而，HRR 与男女混合组的 AIx@75 之间存在关联：r = -0.37，P < 0.001，按性别分类：男性 r = -0.31，P = 0.02，女性 r = -0.38，P < 0.01。
在男女混合组或按性别分类的年轻人群中，HRR 与 CSBP 之间没有关联。大多数 HRR 指标，特别是那些由副交感神经活动建立的指标，与较低的 AIx@75 相关。尽管 HRR 指标可能是心血管疾病的良好指标，但在年轻健康人群中，它们可能不是 CSBP 的良好指标。
