The average heart rate for a 13 year old female, is approximately the same as an adults, which is 60 to 100 bpm. A lower heart rate is common in those who are very athletic. A higher heart rate can be more common in someone with much stress
, a little less active, or someone who drinks a lot of caffeine on a daily basis.
A resting heart rate of 116 is a little high for your age, but it sounds as if you weren't experiencing any symptoms at the time, such as difficulty breathing
, shortness of breath
, sweating, pain et cetera. If you were a little worked up about anything, or had caffeine that day, these could contribute to your higher rate.
Your target heart rate
during exercise can be determine by a formula known as the Karvonen Formula. It is as follows:
220 minus your age X 60% for the lower end and
220 minus your age X 90% for the upper.
Meaning, your target rate during exercise should be between 124 and 186.
It sounds as if your target heart rate, although on the higher side, was still within normal limits for your age group and if you weren't experiencing any abnormal symptoms, I would not worry about it.
If you are concerned about the resting heart rate, I would talk to your family doctor. They can work with you and help you determine why it was a little higher than normal.
Good luck to you! I hope I was able to help out!
