Maximal heart rate ( HR max ) declines substantially with age, but the magnitude and possible modifying effect of gender, body composition, and physical activity are not fully established. The present study examined the relationship between HR max and age in 3320 healthy men and women within a wide age range using data from the HUNT F itness S tudy (2007–2008). Subjects were included if a maximal effort could be verified during a maximal exercise test. General linear modeling was used to determine the effect of age on HR max . Subsequently, the effects of gender, body mass index ( BMI ), physical activity status, and maximal oxygen uptake were examined. Mean predicted HR max by three former prediction formulas were compared with measured HR max within 10‐year age groups. HR max was univariately explained by the formula 211 − 0.64·age ( SEE , 10.8), and we found no evidence of interaction with gender, physical activity, VO 2max level, or BMI groups. There were only minor age‐adjusted differences in HR max between these groups. Previously suggested prediction equations underestimated measured HR max in subjects older than 30 years. HR max predicted by age alone may be practically convenient for various groups, although a standard error of 10.8 beats/min must be taken into account. HR max in healthy, older subjects and women were higher than previously reported.
