目的：建议个体在递增的心肺适能(CRF)测试中不会达到其最大心率(HRmax)，通常在达到的最高心率(HR)的基础上再加上每分钟5次。据我们所知，没有足够的数据证明这种估计是合理的。设计和方法：51名男性和57名女性(年龄22-70岁)完成了CRF递增试验(逐渐增加速度和/或倾斜直到意志性衰竭)和达到最大心率(在最大强度运动前重复高强度运动)的试验，两种试验相隔48h。结果：以HRmax为因变量，以CRF试验是否达到最大摄氧量为自变量，以CRF试验是否达到最大摄氧量为自变量，对两次试验中心率最高值与CRF试验中达到的最高HR之间的关系进行了研究。结果：达到最大心率试验的HRmax比CRF试验高2.2(95%可信区间，1.5~2.9)次/分(p<；0.001)。只有HRCRF显著预测HRmax，模型中的其他变量没有贡献。最大心率由递增CRF测试中达到的最高心率乘以0.967，再加上8.197次/分钟(HRmax=8.197+[0.967 x HRCRF])来预测。(C)2018年由爱思唯尔有限公司代表澳大利亚运动医学出版。
Objectives: It is suggested that individuals will not reach their heart rate maximum (HRmax) at an incremental cardiorespiratory fitness (CRF) test and commonly five beats per minute (bpm) are added to the highest heart rate (HR) reached. To our knowledge, there is not sufficient data justifying such estimation. Our aim was to assess whether individuals reached HRmax in an incremental CRF test to exhaustion.Design and methods: Fifty-one males and 57 females (aged 22-70 years) completed both an incremental CRF test (gradual increase in speed and/or inclination until volitional exhaustion) and a test designed to reach HRmax (with repeated work bouts at high intensity before maximal exertion) >= 48 h apart. We investigated the relationship between the highest HR in the two tests using hierarchical linear regression analysis, with HRmax from the HRmax test as a dependent variable, and the highest HR reached at the CRF test (HRcrf), whether maximum oxygen uptake was reached on the CRF test, CRF, sex and age as independent variables.Results: HRmax was 2.2 (95% confidence interval, 1.5-2.9) bpm higher in the test designed to reach HRmax than in the CRF test (p < 0.001). Only HRcrf significantly predicted HRmax, with no contribution of the other variables in the model. HRmax was predicted from the highest HR reached in an incremental CRF test by multiplying HRcrf with 0.967, and adding 8.197 (HRmax = 8.197 + [0.967 x HRcrf]) beats/min.Conclusion: Non-athletes reached close to HRmax in a standard CRF test.
