Durnin & Womersley Method
Comprehensive analysis of the Durnin & Womersley skinfold method, featuring age-specific equations and extensive validation across different populations. Explore its unique approach to accounting for age-related changes in body composition.
Historical Development
Original Research (1974)
Groundbreaking study addressing age-related variations in body composition:
- Developed age- and gender-specific equations
- Based on four-site skinfold measurements
- Designed to account for age-related changes
Method Evolution
Development and refinement over time:
- 1974: Original equations published
- Subsequent validation across populations
- Continued use in field assessments
