If you are 12 years old, which math problem would give you your maximum heart rate? Response area After finding your maximum heart rate, remember your target heart rate zone is 70-85% of you maximum heart rate, what would be your lower range or your target heart zone? Response area What would be your upper limit?
To calculate your maximum heart rate as a 12-year-old, the formula is 208 - (0.7 x age).
Therefore, your maximum heart rate would be 208 - (0.7 x 12) = 199.6 beats per minute.
Your target heart rate zone would be 70-85% of your maximum heart rate.
Lower range: 70% of 199.6 = 139.72 beats per minute
Upper limit: 85% of 199.6 = 169.66 beats per minute
Therefore, your target heart rate zone would be between 139.72 and 169.66 beats per minute.
