Figure 3 Regression lines depicting the relation between maximal heart rate (HRmax) and age obtained from the results derived from our equation (208 0.7 x age) (solid line with 95% confidence interval), as compared with the results derived from the traditional 220 age equation (dashed line). Maximal heart rates predicted by traditional and current equations, as well as the differences between the two equations, are shown in the table format at the top.
