I want to ask, I like to exercise or be active in sports. Every now and then I am fun to measure my heart rate when running using a smart watch and on the smart watch it shows my heart rate is at 174 / minute. Is that normal? I am still 14 years old
Good afternoon, thanks for the question
Normal heart rate in adolescents under the age of 18 is 70-100 times per minute. Heart rate more than 100 times per minute is classified as fast or tachycardia which can be caused by several conditions, namely:
- Increased body temperature or fever
- Post physical activity
- Consumption of caffeine
- Consumption of certain drugs
- Blood pressure is too low
Normal tachycardia occurs when physical activity is related to the increased oxygen demand that the body responds to by increasing the work of the heart. Heart rate will gradually decrease when the body starts in a relaxed condition. Likewise in your case, the increase in heart rate that occurs is still in normal conditions related to the body's response during physical activity. At your age your body can still compensate for an increase in heart rate up to 195 times per minute.
Take a break and relax for a moment after doing physical activity so that the parasympathetic nervous system works so that the heart rate will decrease.
That's all, hope you can help
