In this study, we compared measured maximal heart rate (HRmax) to two different HRmax prediction equations [220-age and 208-0.7(age)] in 52 children ages 7-17 years. We determined the relationship of chronological age, maturational age, and resting HR to measured HRmax and assessed seated resting HR and HRmax during a graded exercise test. Maturational age was calculated as the maturity offset in years from the estimated age at peak height velocity. Measured HRmax was 201 + 10 bpm, whereas predicted HRmax ranged from 199 to 208 bpm. Measured HRmax and the predicted value from the 208-0.7(age) prediction were similar but lower (p less than 0.05) than the 220-age prediction. Absolute differences between measured and predicted HRmax were 8 + 5 and 10 + 8 bpm for the 208-0.7 (age) and 220-age equations, respectively, and were greater than zero (p less than 0.05). Regression equations using resting HR and maturity offset or chronological age significantly predicted HRmax, although the R[squared] less than 0.30 and the standard error of estimation (8.2-8.5) limits the accuracy. The 208-0.7(age) equation can closely predict mean HRmax in children, but individual variation is still apparent. (Contains 2 tables and 1 figure.)
