A person who is 15 years old has a maximum heart rate of 205. To calculate your approximate maximum heart rate, subtract your age from 220.
Adults typically have a resting heart rate between 60 and 100 beats per minute. A lower resting heart rate typically indicates improved cardiovascular fitness and more effective cardiac function. A well-trained athlete, for instance, might have a typical resting heart rate that is closer to 40 beats per minute.
If your heart rate is routinely over or below 60 beats per minute, or if you are also experiencing shortness of breath, you should see a doctor. episodes of lightheadedness, dizziness, or fainting.
Your heart beats less frequently than 60 times each minute if you have bradycardia. If the heart doesn't pump enough oxygen-rich blood to the body and the pulse rate is exceedingly sluggish, bradycardia can be a major issue.
Thus, A person who is 15 years old has a maximum heart rate of 205.
