What is the Standard Estimate of Error (SEE) for skinfold measurements performed by an expert tester?

The Standard Estimate of Error (SEE) for skinfold measurements performed by an expert tester typically falls within the range of 3-4%. This value indicates the expected potential variation in skinfold measurements when performed under ideal conditions by someone skilled in the technique.

Skinfold measurements are utilized in body composition assessment and depend heavily on the skill level and consistency of the tester. An expert tester’s proficiency helps to minimize variability; however, biological variation among individuals and the measurement process itself can contribute to some margin of error.

This level of SEE reflects the balance between the precision of the technique and the inherent variability in biological measurements. Variability can arise from factors such as changes in hydration status, subcutaneous fat distribution, and even the skillful application of calipers. It is important to understand that while a range of 1-2% might apply to well-controlled laboratory measurements or ideal scenarios, the practical application in diverse human subjects typically aligns more closely with the 3-4% range for expert testers. This understanding emphasizes the importance of experienced professionals in body composition analysis.
