This method estimates body fat percentage by measuring skinfold thickness at seven specific locations on the body. Calipers are used to pinch and measure the subcutaneous fat layer at these sites, and the measurements are then entered into a formula to calculate the estimated body fat percentage. The measurements are typically recorded in millimeters. Common sites include the chest, midaxillary, triceps, subscapular, suprailiac, abdomen, and thigh.
Assessing body composition through this technique provides a relatively inexpensive and non-invasive way to track changes in body fat over time. It is often employed in fitness assessments and research settings to monitor the effectiveness of training programs or dietary interventions. Historically, skinfold measurements have been used as a practical alternative to more sophisticated and costly methods like DEXA scans for evaluating body composition in large populations.
