Hydrostatic Weighing Lab Eat light/ No gas producing foods n Bring suit (towel/plastic bag) n Report to pool deck in suit/bare feet n You will go in order of arrival n When you are done, you may go get dressed n

Procedures Weight scale is hooked to crane & pvc piping chair n Enter pool at ladder making NO waves n Brush off all air, push on air pockets so they fill with water n Ease over to the chair n Enter chair from “block end” of pool n

Procedures Squat in Chair n Place hands under “chair arms” n Weight must be bearing down- not floating up n Exhale some air above water n Ease under water calmly, smoothly n Exhale the remainder of your air n

Readings You will be given a reading of your weight in water n You MUST SUBTRACT the weight of the chair (approximately 2. 6) n Water Temperature=27 degrees c n Estimated Residual Volume n – Boys=1. 3 liters – Girls=1. 0 liters

Calculations Body Density n Body Density= Weight in air (in kg) (Wt. in Air-Wt. in Water) - (RV (liters)+. 1) Density of Water

Calculations Body Density- Sample Weight in water w/ chair= 4. 2 kg n 4. 2 -2. 6=1. 6 kg n Body Density= n 68. 1 Weight in air (in kg) (68. 1 Wt. in Air – 1. 6 Wt. in Water) - (RV 1. 3 liters+. 1). 9968 (26 degree Celsius)

Calculations Percent Body Fat n Suri Equation for Percent Body Fat= 495 Body Density - 450

Calculations Percent Body Fat- Sample n Suri Equation for Percent Body Fat= 495 1. 04 - 450 =25. 96%
