摘　　要：目的:探讨应用年龄预测我国大学生最大心率(HRmax)的有关公式及其有效性。方法:研究招募了101名(20.9±1.52岁)大学生作为测试对象,在运动跑台上完成逐级递增负荷测试(GXT),并获得实测的最大心率值,另以"220-年龄"、"206.9-0.67×年龄"、"205.8-0.685×年龄"、"210-0.66×年龄"等4个常用公式的计算结果为预测值。对测试结果进行统计学分析。结果:配对t检验与单因素方差分析结果显示,"210-0.66×年龄"与实测值没有显著性差异(P>0.05);Bland-Altman点图显示,"210-0.66×年龄"与实测结果的一致性水平较好。结论:"210-0.66×年龄"具有可接受的预测误差水平,在4个公式当中预测大学生人群的HRmax准确性较好。Objective To explore the formula of predicting the maximum heart rate （HRmax） of col- lege students in China from age, and examine its validity. Methods One hundred and one students （aged 20.9 ± 1.52 years） were recruited to undergo the VO2max test,and the HRmax was acquired after they finished the graded exercise test （GXT）. The predicted value was also obtained according to the formulae of the age- predicted Hrmax： ＂205.8-0.685 Xage＂, ＂206.9-0.67 x age＂ and ＂210-0.66 x age＂. Results According to the paired t-test and one-way analysis of the variance, it was found that significant differences were observed between the measured HRmax and all the predicted values except the one got according to the formula of ＂210-0.66xAge＂. Through the method of Bland-Ahman plot, the predicted value of ＂210-0.66Xage＂ was more consistent with the measured value. Conclusion The ＂210--0.66Xage＂ equation owns the acceptable level of prediction error,and is the most suitable one of the four equations to predict the HRmax of college students in China.
