【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(P0.05);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。
[Abstract]:Objective: to explore the formula and effectiveness of age prediction of maximum heart rate (HRmax) in Chinese college students. Methods: 101 college students (20.9 卤1.52 years old) were recruited as subjects. The incremental load test (GXT), was completed on the treadmill and the measured maximum heart rate was obtained, in addition to "220-age". The calculation results of "206.9 鈮，
