What is an acceptable target heart rate for a patient whose age-predicted maximal heart rate is 175 bpm during cardiovascular exercise?

To determine an acceptable target heart rate during cardiovascular exercise, one typically uses the age-predicted maximal heart rate formula, which is often approximated by subtracting the person's age from 220. In this case, with a maximal heart rate of 175 bpm, a target heart rate can be calculated based on a percentage of that maximum.

For moderate-intensity exercise, a target heart rate of around 50% to 70% of the age-predicted maximum is often recommended. This means that for a maximal heart rate of 175 bpm, the acceptable target heart rate should fall within the range of approximately 88 bpm to around 122 bpm, to achieve moderate exercise intensity. For higher-intensity workouts, you could aim for 70% to 85%, bringing the target heart rate to about 122 bpm to about 148 bpm.

The target heart rate of 135 bpm fits into the moderate intensity range, making it a suitable choice for cardiovascular exercise. It reflects a level of exertion that enhances cardiovascular fitness while still being within safe parameters for many individuals based on the age-predicted maximal heart rate.

In contrast, a target heart rate of 93 bpm would be too low for effective cardiovascular training, while
