Two Compartments of Body Composition FM & FFM FM Fat mass - divided into essential fat and storage fat FFM fat-free mass - consists of protein (i.e. muscle), water, and minerals (i.e. bone) 3% Essential Body fat of Males storage fat extra, non-essential fat that includes fatty tissue surrounding internal organs subcutaneous fat fat located just the skin's surface, a part of storage fat Essential fat fat required for normal physiologic functioning. fat incorporated into the organs and tissues 12% Essential Body fat of Females. is higher due to sex specific fat for child-bearing Methods of measuring fat % 1 / 2
Hydrostatic Weighing Skinfold Measurement Bioelectrical Impedance Analysis (BIA) Girth Measurement Direct assessment way to measure body composition only through chemical analysis or a cadaver Hydrostatic Weighing Archimedes' principle of water displacement The gold standard for measuring body composition Hydrostatic weighting - Body volume measured through the determination of bodyweight lost b complete immersion in water Hydrostatic weighing - body density calculated by dividing bodyweight in the air by the body volume Hydrostatic weighing - residual lung volume RV is the volume of air remaining in the lungs after an individual completely exhales all the air that they can downsides to Hydrostatic weighing need huge water tube lmao Skinfold Measurement Calipers to measure subcutaneous fat
- sites (males: chest, abdomen, thigh; females: tricep, suprailiac, thigh)

downsides of skin fold Human error in clipping at muscle instead of pure fat
