Study Notes
Body Fat Overview
- Subcutaneous Fat: Component of body mass, crucial for energy storage and protection of muscles and internal fat.
- Soft Tissue Deficiency: Predominantly occurs when there is a lack of protein and calories, impacting overall body composition.
Measurement Techniques
- Densitometry: An accurate method for measuring body fat, though less practical for field use.
- Physical Anthropometry: Utilizing skin fold calipers, this method is more accessible in field settings to assess nutritional status.
- Caliper Specifications: A standard stable caliper is necessary for accurate skin fold measurements, which incorporate both the double layer of skin and the underlying subcutaneous fat.
Skin Fold Measurement Sites
- Adult Measurement Locations: Primary sites for skin fold measurement include the triceps, abdomen, subscapular, and subcoastal regions.
- Calculation of Body Fat: Various formulas enable the derivation of total body fat from measurements taken at these multiple sights.
