Why is the formula (METs × 3.5 × body weight in kg)/200 preferred for estimating caloric expenditure?

The formula (METs × 3.5 × body weight in kg)/200 is preferred for estimating caloric expenditure because it personalizes the estimate of caloric expenditure based on an individual's weight and the specific intensity of the activity being performed, represented by the METs (Metabolic Equivalent of Task) value.

By incorporating body weight into the equation, the calculation directly links caloric expenditure to an individual's physiological characteristics, making it more accurate for different body sizes. This means that a person who weighs more will naturally burn more calories at the same MET level compared to someone who weighs less, allowing for a more individualized assessment of energy expenditure during exercise.

Additionally, the use of METs allows users to tailor the calculation to various activities with differing intensities, further enhancing the personalization aspect. This is crucial in kinesiology practice since accurate estimation of caloric expenditure can aid in designing effective exercise and nutrition programs based on the specific needs and goals of individual clients. As a result, the formula provides a nuanced approach to understanding how different factors—particularly body weight and exercise intensity—affect calorie burn.
