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

• A. 160 bpm
• B. 175 bpm
• C. 165 bpm
• D. 180 bpm

Answer: (B)

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
