Which skinfold site is NOT a common measurement site?

• A. Biceps
• B. Forearm
• C. Triceps
• D. Subscapular

Answer: (B)

Skinfold assessment relies on measuring subcutaneous fat at several well-established sites because those areas collectively reflect overall body fat more reliably. The common sites are located on the upper arm and trunk—areas that show clearer, more consistent changes with total adiposity across individuals. The forearm, however, is not part of the standard sets used in traditional skinfold protocols. Fat distribution in the forearm varies more with factors like muscle size, hydration, and how the skinfold is taken, making it a less dependable predictor of total body fat. Because of this weaker, less consistent relationship and measurement challenges, forearm skinfolds aren’t typically included in standard body fat assessment procedures.
