Abstract

Objectives: 1) to develop two maximum heart rate (HR_max) prediction equations for individuals after stroke; 2) to investigate its validity.

Methods: The HR_max was obtained by a Cardiopulmonary Exercise Test (CPET). Participants also completed the Six-minute Walking Test (6MWT) and the Incremental Shuttle Walking Test (ISWT).

Results: 60 individuals (54(12) years; 64(69) months after stroke) were included. Twenty individuals (58(10) years; 67(61) months after stroke) were included in the cross-validation group. For the first model, the following equation was generated (equation-1): HR_max= 87.655 + 0.726 (HR_peak in the 6MWT) - 0.386 (age in years), (R²=0.53; Standard Error of the Estimate (SEE)= 15.35; p < 0.0001). For the second model, the following equation was generated (equation-2): HR_max= 96.523 + 0.681 (HR_peak in the ISWT) - 0.039 (walking distance in meters in the ISWT) - 0.400 (age in years), (R²=0.53; SEE = 15.51; p < 0.0001). Significant and high magnitude agreement was found between the HR_max obtained by the CPET and the predicted HR_max by equation-1 (ICC= 0.85; 95% CI= 0.63 - 0.94) and equation-2 (ICC= 0.72; 95% CI= 0.29 - 0.89).

Conclusions: Two HR_max prediction equations have been developed and showed adequate validity. Professionals will have the option of choosing one of the two equations to use.

基于现场测试的最大心率预测方程，对脑卒中患者的有氧运动处方具有充分的临床适用性。

目的1）为中风后的患者制定两个最大心率（HRmax）预测方程；2）研究其有效性：方法：通过心肺运动测试（CPET）获得最大心率。方法：通过心肺运动测试（CPET）获得心率最大值，参与者还完成了六分钟步行测试（6MWT）和增量穿梭步行测试（ISWT）：结果：共纳入 60 人（54（12）岁；中风后 64（69）个月）。交叉验证组包括 20 人（58（10）岁；中风后 67（61）个月）。第一个模型的公式如下（公式-1）：HRmax= 87.655 + 0.726（6MWT 中的 HR 峰值）- 0.386（年龄（岁）），（R2=0.53；估计标准误差（SEE）= 15.35；p max= 96.523 + 0.681（ISWT 中的 HR 峰值）- 0.039（ISWT 中的步行距离（米））- 0.400（年龄（岁）），（R2=0.53；SEE=15.51；CPET 得出的 p max 与方程-1（ICC=0.85；95% CI=0.63-0.94）和方程-2（ICC=0.72；95% CI=0.29-0.89）预测的 HRmax：结论：已开发出两种心率最大值预测方程，并显示出足够的有效性。结论：已开发出两个心率最大值预测方程，并显示出足够的有效性，专业人员可从两个方程中选择一个使用。
