Which of the following is NOT a component of an exercise prescription?

In the context of exercise prescription, heart rate is a measurement used to assess the intensity of physical activity but is not considered a foundational component of the prescription itself. Exercise prescriptions are typically structured around four key components: frequency, intensity, duration, and sometimes type or mode of exercise.

Frequency refers to how often exercise sessions occur (e.g., days per week), intensity pertains to how hard the exercise is performed, and duration indicates the length of time for each exercise session (e.g., minutes spent exercising). These elements combine to provide a comprehensive plan tailored to a person’s fitness goals.

While monitoring heart rate can be crucial for assessing whether the intensity is appropriate during exercise, it does not fit the structural model of how an exercise prescription is formulated. Instead, heart rate is often used as a tool to gauge or adjust the exercise intensity within the established parameters of a prescription.
