Karvonen is known for his work on coronary heart disease and epidemiology and giving the formula for calculating the target heart rate zone during the training called 220-age formula.
The formula is based on the age and resting heart rate of the trainer. To measure the heart rate first the resting heart rate of a person is measured every fifteen-minute.
Then find age-predicted maximum heart rate by subtracting the age of the person from 220.
