Question

question 4 / 5
if someone is 20 years old trying to lose fat, what low and high percentage would she use to build her fat-burning capacity?

a. 50%-60%

b. 60%-70%

c. 70%-80%

d. 80%-90%

Explanation:

To determine the fat - burning heart rate percentage range for a 20 - year - old, we first calculate the maximum heart rate (MHR) using the formula \(MHR = 220 - age\). For a 20 - year - old, \(MHR=220 - 20 = 200\) beats per minute. The fat - burning zone is typically around 60% - 70% of the maximum heart rate. This range is considered optimal for burning fat as it is a moderate - intensity exercise range that allows the body to utilize fat as a primary fuel source.

Answer:

B. 60% - 70%
