Which of the following heart rates from a 30 minute workout fall in the target heart zone for a 15 year old boy

The target pulse rate zone for a 15 year old male to burn fat during light to moderate exercise is 102 to 141 beats per minute1. 15 year old females working out to loose weight should exercise between 96 and 133 bpm. This exercise range corresponds to 50% to 69% of the maximum target rate for your ag

Explanation:

Moderate to Intense Exercise

The American Heart Association recommends hard exercise up to 85% of your maximum heart rate1. The target zone during intense exercise (70% to 85% of maximum heart rate) ranges from 144 to 174 beats per minute for a 15 year old male and between 135 and 164 for females.

Maximum Heart Rate

Maximum heart rate is the upper threshold that your cardiovascular system can sustain during physical exertion. This rate decreases with age. The maximum heart rate for males (HRmax) can be estimated using the Karvonen method as 220 minus your age. So for 15 year old boys, the maximum rate is approximately 205 beats per minute. A modified HRmax formula specific to women has been developed as 206 minus 88 percent of your age2. This method results in a 193 beats per minute maximum pulse for a 15 year old female.
