Using the heart rate reserve method, what is the target heart rate range for a patient with a resting heart rate of 60 bpm and a max heart rate of 180 bpm at 60-80% intensity?

  1. 96 - 120 beats per minute

  2. 132 - 156 beats per minute

  3. 144 - 174 beats per minute

  4. 164 - 185 beats per minute

The correct answer is: 132 - 156 beats per minute

To calculate the target heart rate range using the heart rate reserve (HRR) method, you first need to determine the heart rate reserve and then apply the desired intensity range. Start by calculating the heart rate reserve. The heart rate reserve is found using the formula: HRR = Max Heart Rate - Resting Heart Rate In this case, the max heart rate is 180 bpm, and the resting heart rate is 60 bpm, so: HRR = 180 bpm - 60 bpm = 120 bpm Next, calculate the target heart rate range at 60% to 80% of the heart rate reserve, adding the resting heart rate back into the equation. For 60% intensity: Target Heart Rate = (HRR x 0.60) + Resting Heart Rate Target Heart Rate = (120 bpm x 0.60) + 60 bpm Target Heart Rate = 72 bpm + 60 bpm = 132 bpm For 80% intensity: Target Heart Rate = (HRR x 0.80) + Resting Heart Rate Target Heart Rate = (120 bpm x 0.80) + 60 bpm Target Heart Rate = 96 bpm + 60
