摘要：Colantonio E, Kiss MAPDM. Is the HRmax=220-age Equation Valid to Prescribe Exercise Training in Children? JEPonline 2013;16(1):19- 27. The estimation of maximum heart rate (HRmax) has been largely based on the formula HRmax=220-age. This equation is well-known in exercise physiology and yet, the formula was not developed from original research. The purpose of this study was to compare the HRmax predicted by the formula and HRmax measured during an exercise test performed to exhaustion in a large range of age group (according to gender and training level). The sample was composed by 145 subjects (74 females and 69 males) that ranged from 7-17 yr, which was divided into pupils (untrained) and swimmers (trained). The data were obtained from a gas analysis system during an incremental treadmill protocol. The subjects’ HR was monitored by ECG while HRmax was estimated using the HRmax=220-age equation. The findings indicated that the equation overestimated HRmax during a maximal incremental test in children and youths. Also, gender and training level were not related to the HRmax, independently if HRmax was predicted or measured. Therefore, the HRmax=220-age equation is not recommended for exercise training in children.
