Answer:
A. Peak maximal heart rate (MHR)
Step-by-step explanation:
The Karvonen method is simply a Mathematics formula which helps in calculating the Maximum or Target Heart Rate.
This is achieved my by using the outcome of the Maximum heart rate and and resting heart rate combined with the desired training procedure to get the target heart.
The formulae is;
Target Heart Rate = [(max HR − resting HR) × %Intensity] + resting HR
The maximum heart rate can be determined when one subtracts his age from 220. In that case a 40years old man can say his maximum heart rate is 220-40=160.
