If you are 13 years old, which math problem would give you your maximum heart rate? If you are 13 years old, what is your maximum heart rate? After finding your maximum heart rate, remember your target heart rate zone is 70-85% of you maximum heart rate. What would be the lower range or your target heart zone? Response area What would be the upper limit? Response area
The math problem to find maximum heart rate is as follows:
Maximum Heart Rate = 220 - age
For a 13-year-old, the maximum heart rate would be:
Maximum Heart Rate = 220 - 13
Maximum Heart Rate = 207 beats per minute
To find the lower range of the target heart rate zone (70% of maximum heart rate), you would calculate:
70% of 207 = 0.7 x 207 = 144.9
The lower range of the target heart rate zone would be approximately 145 beats per minute.
To find the upper range of the target heart rate zone (85% of maximum heart rate), you would calculate:
85% of 207 = 0.85 x 207 = 175.95
The upper range of the target heart rate zone would be approximately 176 beats per minute.
