Using the Karvonen Method outlined in the Clinician Resources, what would be the target heart rate for a 56 year old male prescribed to work at 50% intensity with a resting heart rate of 92?
130
140
145
135

Answer :

Answer:

Explanation:

To calculate the target heart rate using the Karvonen Method, you first need to find the heart rate reserve (HRR) by subtracting the resting heart rate (RHR) from the maximum heart rate (MHR).

The maximum heart rate (MHR) can be estimated using the formula: 220 - Age.

For a 56-year-old male:

MHR = 220 - 56 = 164 beats per minute (bpm)

Now, we calculate the heart rate reserve (HRR):

HRR = MHR - RHR

= 164 - 92

= 72 bpm

Now, to find the target heart rate at 50% intensity:

Target Heart Rate = (HRR * Intensity) + RHR

= (72 * 0.50) + 92

= 36 + 92

= 128 bpm

So, the target heart rate for a 56-year-old male prescribed to work at 50% intensity with a resting heart rate of 92 would be approximately 128 bpm.

So, none of the given options match the calculated target heart rate.
