If you are 12 years old, which math problem would give you 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 your lower range or your target heart zone? What would be your upper limit?
To calculate the maximum heart rate (MHR) for a 12-year-old, you can use the formula: MHR = 220 - age.
For a 12-year-old, the maximum heart rate would be: MHR = 220 - 12 = 208 beats per minute (bpm).
To calculate the lower range or target heart rate zone, you need to find 70-85% of the maximum heart rate:
Lower range of the target heart rate zone = 70% of MHR
Lower range = 0.7 * 208 bpm = 145.6 bpm (rounded to 146 bpm)
Upper limit of the target heart rate zone = 85% of MHR
Upper limit = 0.85 * 208 bpm = 176.8 bpm (rounded to 177 bpm)
So, for a 12-year-old, the lower range or target heart rate zone would be 146 bpm, and the upper limit of the target heart rate zone would be 177 bpm.
what would the upper limit be from the answer choices 220+12, 170, 208, 200+12, 220-12, 100, or 150
From the given answer choices, the correct option for the upper limit of the target heart rate zone for a 12-year-old would be "220-12".
The formula to find the maximum heart rate (MHR) is MHR = 220 - age. In this case, the age is 12, so the MHR becomes 220 - 12 = 208 bpm.
To determine the upper limit of the target heart rate zone, we multiply the MHR by 85% because it corresponds to 85% of the maximum heart rate:
Upper limit = 0.85 * 208 bpm = 176.8 bpm (rounded to 177 bpm).
Therefore, the correct upper limit of the target heart rate zone for a 12-year-old would be "220-12".
