Karvonen formula | definition of Karvonen formula by Medical dictionary
Karvonen formula (kăr-vōn′ĕn)
A calculation of the optimal range of heart rate for achieving physical fitness during cardiovascular endurance exercise. The calculation is based on a percentage of predicted maximum heart rate of 220 minus the person's age (HRmax) and the resting heart rate (HRrest). The formula that determines the best physical training range is: HR = HRrest + (HRmax − HRrest) (.60 to .80).

An alternative to the two HRmax equations mentioned above to estimate the high-intensity effort, you could use the Heart Rate Reserve (HRR) method, also known as the Karvonen formula
Target heart rate can be calculated by using the Karvonen formula
The most widely accepted method of determining training zone for the purpose of inducing an aerobic endurance training effect in CR appears to be utilization of heart rate, either using the Karvonen formula or percent of maximum heart rate.

1) Karvonen Formula
220 -Age = Maximum Heart Rate Max Heart Rate--Resting Heart Rate x Intensity + Resting Heart Rate = Training Heart Rate
We monitored cardiac safety and initially ensured that subjects did not exceed 10 to 20 min at 40 to 50 percent of maximal HR reserve, as calculated by the Karvonen formula
