Question

1. which statement about target heart rate is true?

if you are already very fit, aim for the low end of your target heart rate range.
when starting a fitness routine, aim for the high end of the target heart rate range.
you can find your target heart rate by subtracting your age from 220.
your target heart rate is 65 percent to 90 percent of your age - predicted maximum heart rate.

Explanation:

• The formula for age - predicted maximum heart rate is \( \text{Maximum Heart Rate}=220 - \text{Age}\). Target heart rate is typically \(65\%\) to \(90\%\) of this maximum heart rate.
• If very fit, one can aim for the higher end of the target heart rate range as they have a better cardiovascular capacity. When starting a fitness routine, aiming for the lower end is more appropriate to avoid over - exertion. Just subtracting age from 220 gives the maximum heart rate, not the target heart rate.

Answer:

Your target heart rate is 65 percent to 90 percent of your age - predicted maximum heart rate.
