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 find your maximum heart rate, a common formula is to subtract your age from 220. So, for a 12-year-old, the maximum heart rate would be 220 - 12 = 208 beats per minute (bpm).
To calculate the lower range or target heart zone, you can multiply the maximum heart rate by the lower percentage value of the target heart rate zone (70%). Therefore, 70% of 208 bpm is 0.70 * 208 = 145.6 bpm.
The upper limit of the target heart zone can be calculated by multiplying the maximum heart rate by the upper percentage value of the target heart rate zone (85%). Therefore, 85% of 208 bpm is 0.85 * 208 = 176.8 bpm.
So, the lower range of the target heart zone would be approximately 146 bpm, and the upper limit would be approximately 177 bpm.
