Training Heart Rate Calculator (%HHR Calculator)
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.
Use this THR calculator (Heart Rate Reserve/Karvonen method) if you:
- Know your average daily Resting Heart Rate
- Know your actual maximal Exercise Heart Rate
(before the onset of angina or ECG ST/T segment changes on a GXT)
If you have a pacemaker
- Enter your 'base rate' as your Resting Heart Rate (but not your Hysteresis rate)
- Enter your Upper Tracking Rate or Upper Pacing Rate as your Maximum Heart Rate.
