What does the physical activity energy expenditure (PAEE) formula include?

The correct answer includes the specific equation used to estimate a person's physical activity energy expenditure (PAEE). The formula provided—637 + (0.39 X min/wk)—is specifically designed to help calculate how much energy is expended through physical activity based on the duration of exercise expressed in minutes per week.

This approach integrates a constant to account for the basal metabolic rate and adds a factor that correlates with the amount of time spent in physical activity, which is key to measuring energy expenditure related to exercise. Understanding this formula allows practitioners to assess how active an individual is and to quantify the calorie expenditure associated with their physical activity levels.

In comparison, the other options do not directly represent the PAEE formula. Weight, height, and age are often parameters used in various fitness calculations but do not specifically define energy expenditure from physical activity. Similarly, calories consumed and burned pertain more to overall energy balance rather than specifically to PAEE. Lastly, while fat mass and muscle mass can influence overall metabolism and calorie expenditure, they are not part of the specific PAEE calculation.
