Overview :

Tanaka et al developed formulas for predicting maximal heart rate in healthy adults during exercise. These were derived to provide more accurate predictions than previous equations. The authors are from the University of Colorado in Boulder and the University of Colorado Health Sciences Center in Denver.

 

Problem with the usual formula for calculating maximal heart rate (see above) is that it tends to underestimate maximal heart rate in older adults. Exercise prescription using this formula results in less than intended exercise intensity.
