Stefan is a healthy man who is 26 years of age.Using this information,calculate his approximate target heart rate zone for vigorous-intensity physical activity.

Question

Quizplus · Accepted Answer

To calculate the approximate target heart rate zone for vigorous-intensity physical activity, we can use the formula: 220 - age = maximum heart rate.

Therefore, Stefan's maximum heart rate (MHR) is 220 - 26 = 194 beats per minute (bpm).

The American Heart Association recommends that vigorous-intensity physical activity should be performed at 70-85% of the MHR.

Using this range, we can calculate Stefan's target heart rate zone for vigorous-intensity physical activity as follows:
- Lower end of target zone: 194 bpm x 0.7 = 136 bpm
- Upper end of target zone: 194 bpm x 0.85 = 165 bpm

Therefore, Stefan's approximate target heart rate zone for vigorous-intensity physical activity is 136 to 165 bpm, which is option B).
