Heart rate basics study guide Reading: The surprising history of the HR max What is the origin of the HR max equation: 220-age? How was the equation derived? Surprisingly, there is no published record of research for this equation. The origin of the formula is a superficial estimate, based on observation, of a linear best fit to a series of raw and mean data compiled in 1971. When a linear regression equation was derived from the data from which 220 – age was concluded did this regression formula support 220 – age. The formula HRmax = 220-age has no scientific merit for use in exercise physiology and related fields. Is there a current formula that provides acceptable accuracy of HR max prediction? Currently there is no acceptable method to estimate HRmax. Is it true that we all have an upper maximum value for HR – one that cannot be surpassed? Research for the last 100 years has demonstrated that heart rate does in fact have a maximal value; one that cannot be surpassed despite continued increases in exercise intensity or training adaptations. What is the most important application of the HR response to exercise? Perhaps the most important application of the heart rate response to exercise has been the use of submaximal heart rate, in combination with resting and maximal heart rate, to estimateVO2 max. In Astand’s research what was the average decrease of HR max over 21years for women. How about over 33 years? Do these data support 220 – age? Astrand found that the average decrease in HR max for women was 12 beats in 21 years and 19 beats in 33 years. No because according to the equation we should lose one beat ever year. How does endurance training affect HR max ? A Zavorsky study showed that endurance training lowers HRmax. What is the conclusion regarding current HR max prediction equations when prescribing exercise training HR ranges? For example, a HR of 150 b/min, which lies in the center of the “true” heart rate prescription
