Answer:
b. Karvonen formula
Step-by-step explanation:
The question ask us to select one so i'm going to stick with the Karvonen Formula. The Karvonen Formula is also known as the Heart Rate Reserve (HRR).
Karvonen Formula emphasize on the quest of looking for the Heart Rate Reserve (Target Heart Rate) by the complex interplay between the combination of finding the Resting Heart Rate and the Maximum Heart Rate. The resting heart rate is said to be potential (i.e to be at rest).
The aim of employing the Karvonen Formula (Heart Rate Reserve Method) is to find out the training intensity based on the difference between someone’s predicted maximal heart rate (MHR) and resting heart rate (RHR).
∴ The Karvonen Formula is given as:
HHR =[(HR max- HR Min) x desired intensity] + HR Rest.
