Which skinfold site is NOT included in the skinfolds test?

The correct choice is based on the commonly accepted skinfold measurement sites used in body composition assessments, particularly following protocols like those from the Jackson-Pollock method. In this standard approach, the belly or abdominal area is not one of the traditional skinfold locations measured for assessing body fat percentage.

The chest/pec, thigh, and suprailiac are all recognized sites for skinfold measurements, used to estimate subcutaneous fat in a reliable manner. The chest/pec is relevant for males, while the thigh represents a large area of muscle and fat, and the suprailiac site is often included due to its location just above the iliac crest, which gives valuable insight into fat distribution and overall body composition.

In contrast, the belly or abdominal area, while it may seem logical to measure, is generally excluded from standardized tests in favor of these other sites that provide a more consistent basis for analysis and are less influenced by factors like posture or the immediate distribution of weight in individuals. This standardization helps improve the reliability of the results across different populations and practitioners. Thus, the belly is not included in the classic set of sites for skinfold testing.
