What is the primary purpose of measuring skinfold thickness in fitness assessments?

• A. To Measure Endurance
• B. To Assess Body Composition
• C. To Assess Hydration
• D. To Gauge Flexibility

Answer: (B)

Skinfold thickness measurements are used to estimate body composition by quantifying subcutaneous fat. By pinching specific sites and measuring with calipers, these values feed into validated equations to estimate percent body fat. The main purpose is to understand how much of the body is fat versus lean tissue, which helps track changes during training and guide nutrition and exercise decisions. It doesn’t measure endurance, hydration, or flexibility, which require other assessments. Keep in mind that accuracy relies on proper technique, site choices, and the equation used, and hydration can subtly influence readings.
