Which method, also known as the karvonen method, is used for establishing training intensity based on the difference between a client’s predicted maximal heart rate and his or her resting heart rate? a. peak maximal heart rate (mhr) method b. heart rate reserve (hrr) method c. ratings of perceived exertion (rpe) method d. peak metabolic equivalent (met) method

The correct answer will be option-B

Explanation:

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.

The heart rate reserve is calculated then by subtracting the resting heart rate from the maximal heart rate.

Thus, Option-B is the correct answer.
