Commonly referred to as the "gold standard" for body composition assessment (accuracy +/-1 - 1.5% error). Hydrostatic weighing involves sitting in a chair suspended from a scale in a tank of warm water. You will be asked to exhale all of the air from your lungs while you are completely immersed underwater, during which your weight is measured. The Exercise Science Lab Director (Terence Moriarty - [email protected]) will email you regarding scheduling following receipt of payment or you can email and schedule in advance of payment (either works).
