Which site is NOT included in the 7-site formula for skinfold measurements?

The mental calf is not included in the 7-site formula for skinfold measurements. The 7-site skinfold test is typically conducted to estimate body fat percentage and involves measuring skinfold thickness at specific locations on the body, which include the chest, thigh, subscapular area, abdomen, triceps, suprailiac, and midaxillary.

Measuring at these specific sites allows for a standardized approach that has been validated for its accuracy in estimating body composition. The areas included in the formula are chosen based on their ability to reflect overall body fat and are accessible for measurement with a caliper, contributing to reliable data. The calf, although a potential site for skinfold measurement, is not part of the established 7-site protocol, underscoring the reason why it is not a valid choice in this context. This distinction is crucial for practitioners to adhere to standardized protocols when assessing body composition.
