摘　　要：目的:探讨运动实践中最大心率的间接推算方法的信度。方法:采用文献资料研究法,对运动中最大心率的主要应用,最大心率的推测公式及其选择进行了综述。结果:最大心率在运动实践中具有重要意义,可以用于确定运动强度,反映主观用力程度,确定运动终点,推算最大吸氧量。最大心率推算公式繁多,从1938年开始就有人在这方面进行研究,Fox在1971年提出的HRmax=220-年龄,无论其信度和效度都值得商榷,目前国内外关于最大心率的推算公式有20多个。针对不同个体,其最大心率的推算应当选择适用。结论:用传统的220-年龄推算最大心率不够准确,不同群体的最大心率应当选择不同公式。AIM:To discuss the reliability of the indirect method for the estimation of the maximal heart rate(HRmax) during exercise. METHODS:The primary application of the HRmax during exercise,the formulas of predicting HRmax and its selection were reviewed with the methods of documentation. RESULTS:The HRmax was significant during exercise,it could be used to prescribe exercise intensities, reflect peak exertion,determine exercise termination and predict the maximal oxygen uptake.There were a lot of formulas for the prediction of HRmax,which was studied from the year of 1938.The reliability and validity of the formula of “HRmax=220-Age',which was brought out by Fox, needed further investigation There were more than 20 formulas for predicting HRmax at home and abroad.For different people,the prediction of HRmax should select different formula. CONCLUSION:The HRmax estimated with the formula of “HRmax=220 -Age' is not accurate enough.For different people,the prediction of HRmax should select different formula.
