For a 45-year-old, what is the calculated Target HR?

To calculate the target heart rate (HR) for a 45-year-old individual, one common method is to first determine the estimated maximum heart rate. This can be calculated using the formula: 220 minus the individual's age.

For a 45-year-old, the maximum heart rate would be calculated as follows:

220 - 45 = 175 bpm

To establish a target heart rate, it is typical to take a percentage of the maximum heart rate, depending on the intensity level of the exercise. For moderate-intensity exercise, this might range from 50% to 70% of the maximum HR, while high-intensity exercise could range from 70% to 85%.

If one were to use 85% as a common value for high-intensity exercise when calculating the target HR, the calculation would be:

175 bpm (maximum HR) x 0.85 = 148.75 bpm, which would be approximately 149 bpm for targeting high-intensity workouts.

However, in different contexts, you may find other calculations or percentage recommendations leading to different interpretations of "target HR." The choice of 175 bpm as a target HR represents the maximum rate determined for high-intensity or vigorous efforts.

In this instance, the choice
