A New York Times article was brought to my attention by a regular user here at the Trudy Fitness Center.
The article, titled Maximal Heart Rate discusses the old and now new way to calculate an individuals maximal heart rate in the Wellness section on The New York Times website.
The highest heart rate an individual can achieve without severe problems through exercise stress (wikipedia) defines maximal heart rate. Knowing this number is important for determining different intensities for cardiovascular exercise. For example, a 25 minute elliptical workout maintaining 60 percent of your maximal heart rate.
A simple, very common but outdated way to find out an individuals maximal heart rate is to subtract their age from the number 220 (220 – age). This article by The New York Times explains the problems with this method and why the new method of taking 64% of the individuals age then subtracting that number from 211 is more accurate.
Maximal Heart Rate = 211 – (age x 64%)
