Which is a common measure of body fat percentage that involves pinching skinfolds with a caliper?

• A. Skinfolds
• B. BMI
• C. Waist circumference
• D. BMR

Answer: (A)

Measuring body fat percentage with skinfolds using a caliper directly assesses the thickness of fat under the skin at specific sites. By pinching a fold of skin and underlying fat and recording the thickness, and then applying a standard equation, you get an estimate of overall body fat. This approach is common because it is relatively inexpensive, portable, and quick, and with proper technique it provides a reasonably accurate picture of fat percentage compared to methods that don’t measure fat directly. Other options don’t fit as well. BMI uses only height and weight and doesn’t measure fat. Waist circumference reflects abdominal girth but not total body fat percentage. BMR measures energy expenditure at rest, not fat mass. The caliper method’s strength lies in its direct measurement of subcutaneous fat at multiple sites to estimate total body fat.
