Mathematical Formula & Scientific Methodology

Formula: Tanaka et al. Age-Predicted HRmax (2001)

HRmax = 208 - (0.7 × Age)

Meta-analysis published in the Journal of the American College of Cardiology showing 220 - age significantly underestimates HRmax in older adults.

Scientific Limitations

  • Standard deviation is approximately ±10 to 12 bpm across individuals

Peer-Reviewed Scientific Citations

Age-predicted maximal heart rate revisited (2001)

Tanaka H, Monahan KD, Seals DR (2001) — Journal of the American College of Cardiology, 37(1), 153-156

Key Finding: HRmax = 208 - (0.7 * age). Validated across 18,712 subjects as significantly more accurate than the traditional 220 - age equation.
