Body Composition Testing

Body composition testing (also referred to as percent body fat testing) can be performed using several techniques. Body composition methods available at SFSU include: 1)hydrostatic weighing, 2) air displacement plethysmography, and 3) the skinfold technique.

1) Hydrostatic (or underwater) weighing is one of the most accurate techniques that involves a person being weighed while submerged in a tank of water. ( 2% error)

2) Air displacement plethysmography, via our Bod Pod, is also extremely accurate and estimates percent body fat by measuring the amount of air a person displaces. ( 3% error)
3) The skinfold technique assesses the thickness of skinfolds taken at various parts of the body. This method is quicker, with a slightly higher margin of error. (3.5% error)
