Abstract

Introduction: The assessment of maximal heart rate (HRmax) based on the equation HRmax = 220-age has been a central parameter of exercise physiology and applied clinical sciences for almost a century. This equation is often presented without referencing the original research.

Objectives: Cardiorespiratory fitness (CRF) is an important clinical variable and can be associated with morbidity, mortality, reduced health-related quality of life, dysfunction, and loss of independence. CRF decreases with age, but the relationship between aging in years and CRF parameters is not so clear-cut. The problem with using the HRmax = 220-age equation is one of accuracy. Underestimating the maximal heart rate by just six beats per minute (bpm) results in an error of 350 mL/min in the estimated V02max. In other words, for a 75-kg person, this translates to an error of -8.3% or -4.7 mL/kg/min.

Methods: A literary review using keywords “maximum heart rate” in PubMed and Google Scholar studying the most cited and cross referenced articles.

Results: The HRMax = 220 is not based on original research.

Conclusion: Individualized testing prevents the errors of the old HRmax = 220-age equation both in clinical and athletic medicine.

Keywords: Maximal Heart Rate; Cardiorespiratory Fitness; VO2 Max; Maximal Oxygen Consumption; Wireless Heart Monitors
