卡沃宁公式被广泛用于估计运动强度，它将最大心率(HRmax)作为变量。这项研究使用踏板实验来评估建议的计算最大心率公式中的哪一个最适合与卡沃宁公式一起使用。首先，进行了两种涉及测功机的实验：一天一次的实验，一天测试八个踏板负荷；以及一天一次的实验，每天测试一次负荷，持续八天。对7名受试者的数据比较表明，全天型实验更适合于评估HRmax公式，至少对于我们实验中测试的负荷水平是这样。对47名受试者的实验数据进行了统计分析，得出两个HRmax公式适用于卡沃宁公式，以估算20岁S男性的运动强度。此外，还确定了对运动强度影响最大的人的身体特征。
The Karvonen formula, which is widely used to estimate exercise intensity, contains maximum heart rate,HRmax, as a variable. This study employed pedaling experiments to assess which of the proposed formulas for calculatingHRmaxwas the most suitable for use with the Karvonen formula. First, two kinds of experiments involving an ergometer were performed: an all-in-one-day experiment that tested eight pedaling loads in one day, and a one-load-per-day experiment that tested one load per day for eight days. A comparison of the data on 7 subjects showed that the all-in-one-day type of experiment was better for assessingHRmaxformulas, at least for the load levels tested in our experiments. A statistical analysis of the experimental data on 47 subjects showed two of theHRmaxformulas to be suitable for use in the Karvonen formula to estimate exercise intensity for males in their 20 s. In addition, the physical characteristics of a person having the greatest impact on exercise intensity were determined.
