We aimed at determining whether body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR) are associated with heart rate recovery (HRR) and to demonstrate which of the three indices of obesity, is the strongest predictor of HRR in apparently healthy non-obese adults. Three hundred and twenty-five subjects aged 18-66 years participated in the study. Anthropometric indices were measured, and subjects performed cycle ergometer exercise at 75-85% maximum heart rate. Heart rate (HR) was measured during the last minute of exercise and in the first minute of post-exercise recovery. A partial correlation test and a multiple linear regression analysis, after adjusting for age and peak oxygen uptake indicated that the best predictors of HRR were BMI in males and WHR in females. The present data suggest that, HRR is independently related to indices of obesity-BMI, WC, and WHR and strengthen the usefulness of these anthropometric indices in predicting cardiovascular risks. In addition, the findings suggest that BMI in men and WHR in women best express the relationship between obesity and cardiovascular risks.
我们旨在确定体重指数（BMI）、腰围（WC）和腰臀比（WHR）是否与心率恢复（HRR）相关，并证明肥胖的三个指标中，哪一个是预测健康非肥胖成年人 HRR 的最强指标。325 名年龄在 18-66 岁的受试者参加了这项研究。测量了人体测量学指标，受试者在 75-85%最大心率下进行了自行车测力计运动。在运动的最后一分钟和运动后恢复的第一分钟测量心率（HR）。在调整年龄和最大摄氧量后，部分相关测试和多元线性回归分析表明，HRR 的最佳预测因子是男性的 BMI 和女性的 WHR。目前的数据表明，HRR 与肥胖指标（BMI、WC 和 WHR）独立相关，这些人体测量学指标在预测心血管风险方面具有重要意义。此外，研究结果表明，男性的 BMI 和女性的 WHR 最能表达肥胖与心血管风险之间的关系。
