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?Response area
Your maximum heart rate can be estimated using the formula: 220 - age.
For a 12-year-old, the maximum heart rate would be: 220 - 12 = 208 beats per minute.
To calculate the lower range or target heart rate zone, you would use the range of 70-85% of the maximum heart rate.
Lower range (70%): 0.70 x 208 = 145.6 beats per minute
Upper range (85%): 0.85 x 208 = 176.8 beats per minute
Therefore, the lower range or target heart rate zone would be approximately 146 to 177 beats per minute.
