What would be a person target heart rate be if they are 14 years old?

I know it starts like 220-14=206 but then what...
Please help

To calculate the target heart rate for a 14-year-old, you can use the formula:

Target Heart Rate (THR) = Maximum Heart Rate (MHR) x Target Heart Rate Zone

First, let's calculate the maximum heart rate (MHR) using the formula: 220 - age.

MHR = 220 - 14
MHR = 206

Now, to determine the target heart rate (THR) zone, you need to consider the intensity level during exercise. The American Heart Association recommends a target heart rate zone of 50-85% for moderate to vigorous exercise.

To find the lower limit of the target heart rate (50% of MHR):
Lower Limit THR = 50% x MHR
Lower Limit THR = 50% x 206
Lower Limit THR ≈ 103

To find the upper limit of the target heart rate (85% of MHR):
Upper Limit THR = 85% x MHR
Upper Limit THR = 85% x 206
Upper Limit THR ≈ 175

Therefore, the target heart rate for a 14-year-old during exercise should range between approximately 103 beats per minute (lower limit) and 175 beats per minute (upper limit). This range ensures that the exercise is challenging enough to benefit cardiovascular fitness without putting excessive strain on the heart.
