Holly is a healthy woman who is 22 years of age. using this information, calculate her target heart rate zone for moderate-intensity physical activity.

99 to 138.6 bpm

Explanation:

The heart rate of an individual is a measure of how many times the heart beats in a given time, usually measured in beats per minute (bpm).

Resting heart rate is the number of beats per minute when an individual at rest. Generally, it can be understood that the lower the resting heart rate, the more physically fit an individual is.

The maximum heart rate for an individual is 220 minus their age. The target heart rate for moderate physical activity is 50-70% of the maximum heart rate and for vigorous physical activity it is 70-85% of the maximum heart rate.

Based on Holly's age, her maximum heart rate is 220 - 22 = 198 bpm

Her heart rate zone for moderate physical activity is 50-70% of 198 bpm: 99 to 138.6 bpm

Her heart rate zone for vigorous physical activity is 70-85% of 198 bpm: 138.6 to 168.3 bpm
