摘　　要：目的:对健康中年人最大心率(HRmax)的推算公式"HRmax=220-年龄"进行验证,并找到合适的运动负荷试验法。方法:以健康中年人为研究对象,所有受试者进行了功率车递增负荷试验(BGXT);经BGXT筛选的人群进行了跑台递增负荷试验(TGXT),直接获得HRmax。结果:BGXT和TGXT测出的健康中年人HRmax无性别差异(P>0.05);TGXT与BGXT测得的HRmax有明显的差异(P<0.05);TGXT实测HRmax有与"220-年龄"推算值无显著性差异(P>0.05),参加TGXT人群和未参加TGXT人群的BGXT结果有显著性差异(P<0.05)。结论:健康中年人的最大心率不存在性别差异;跑台试验所测最大心率值明显高于功率车试验结果,采用功率车计功器测试中年人的最大心率准确性差;"220-年龄"仅适用于功能能力高的健康中年人。Objective：To validate the calculation of maximal heart rate （HRmax）and find the best GXT for the middle - aged healthy people. Methods： All the subjects took the bicycle graded exercise testing（BGXT）. 20 of them with good health seceleted from BGXT took atreadmill graded exercise testing （TGXT）. Results：There is no different between the males＇ HRmax and the females＇ whether with BGXT or TGXT（ P 〉 0.05） .The HRmax from the BGXT is different from the TGXT（ P 〈 0.05） .The HRmax, from the BGXT is different from the Formula of ＂HRmax = 220 - Age＂ （ P 〉 0.05 ）. Conclusion ： There is no different between the males＇ HRm~ and the females＇. The HRmax From the BGXT is significantly lower than that from the TGXT, and the BGXT is not fit for the testing of the HRmax of middle - aged healthy people .The calculation of ＂220 - Age＂ is just fit for the middle - aged healthy people with high functional capacity.
