Durnin & Womersley Method
PROA scientifically validated 4-site skinfold method that accounts for age-related changes in body composition. Particularly accurate for adults across different age groups.
Method Overview
Developed by Durnin and Womersley in 1974, this method uses age-specific equations to account for changes in fat distribution patterns across different age groups. The method has been extensively validated in research settings.
- Accuracy: ±3.5-5% compared to hydrostatic weighing
- Age-specific equations for better accuracy
- Validated across age groups 17-72
- Accounts for age-related changes
- Strong scientific validation
Measurement Protocol
Measurement Sites
Required Sites:
- Biceps (front of upper arm)
- Triceps (back of upper arm)
- Subscapular (under shoulder blade)
- Suprailiac (above hip bone)
Measurement Tips:
- Take measurements on the right side
- Mark measurement sites before starting
- Use consistent caliper pressure
- Take readings 2 seconds after applying pressure
- Record age accurately for equation selection
