What type of body fat measurement involves using calipers?

Skinfold measurement is a technique used to estimate body fat by measuring the thickness of skinfolds at various sites on the body with calipers. This method relies on the principle that a certain proportion of total body fat is stored subcutaneously (under the skin) and can be represented by the thickness of skinfolds.

In practice, trained professionals typically take measurements at several standard locations, such as the abdomen, triceps, and thigh, among others. These measurements are then used to calculate body fat percentage using established formulas. This method is particularly valued for its simplicity, non-invasiveness, and cost-effectiveness, making it accessible for many fitness and health professionals.

The other options listed represent different methods of body composition analysis. Bod Pod measurements involve air displacement to assess body volume and calculate body density. Hydrostatic weighing uses water displacement to measure body fat, and bioelectrical impedance measures body composition based on the resistance of body tissues to electrical currents. Each of these methods has its own unique approach and equipment, but none utilize calipers directly as the skinfold measurement does.
