%PMHR ( Predicted Maximal Heart Rate ) Calculator

This calculator tests the findings of Robergs and Landwehr (2002). Using age to predict Maximal Heart Rate you will be able to compare your actual ' real-life ' Maximal Heart Rate against the formulae of various researchers. Once you have used it or if you know of other %MHR formulae, then email me with your feedback and suggestions putting ' %MHR formulae ' in the subject line. Members please leave your feedback in the Forum titled ' Training Tips '.

*IMPORTANT

The best and safest way to discover your maximal heart rate is to have a Graded Exercise Test ( GXT ) in a hospital setting where your ECG and blood pressure is monitored throughout the test by medical professionals.
