Maximum heart rate (HRmax) declines with age and sets the ceiling for training zones used to optimise workouts across different intensity levels.

단계별 가이드

1Fox formula: HRmax = 220 − age (most used)
2Tanaka formula: 208 − 0.7 × age (more accurate ≥ 40)
3Individual HRmax varies ±10–20 bpm from formula
4Training zones are % ranges of HRmax

HRmax = 178 bpm; Zone 2 (60–70%): 107–125 bpm

자주 묻는 질문

Is max heart rate the same for everyone my age?

No. Estimates are averages; individual variation ±10–20 bpm. Athletes have higher true max; sedentary may have lower. Genetic factors, fitness level matter. Direct measurement (stress test) most accurate.

Should I exercise at max HR?

No. Dangerous and unnecessary. Training zones: 50–70% max = moderate (cardio), 70–85% = vigorous (intervals). Max HR approach is asymptotic, rarely sustainable.

Does age-predicted max matter if I'm fit?

Less so if you monitor perceived exertion / power output. Fit athletes may exceed age-predicted max. Use max HR for workout zone guidance, not hard rule.
