Document Summary

Skinfold: subcutaneous fat-roughly 1/3 of total body fat percentage, pros: With training, can be quite accurate: cons: Error: person who does calipers is not trained properly: numbers placed into jackson pollack equation, which gives body density (db). Db goes into siri equation ((495/db) -450) which gives tbf. Ht/wt/volume, you can find db then plug into siri equation to find tbf. Bodpod-body fat percentage: air displacement plethysmography, trying to find volume displacement o then find density, then % body fat, pros. Easy to conduct in comparison to hydrostatic weighing: cons. Expensive, not easily accessible: scale=mass, air displacement=volume. Bia: biostatic impedance assessment, percent body fat, found by electrical impedance (resistance), pros: Status of participant can lead to error. Clothing, what they"ve been doing (exercise, dehydrations, etc) Waist circumference: visceral and subcutaneous fats, pros: Pear gynoid healthier of two because more fat around vital organs, less efficiently they work.
