HBIO 202 LAB FINAL EXAM QUESTIONS AND ANSWERS WITH
COMPLETE SOLUTIONS GRADED A++
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 %
, 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
3 sites (males: chest, abdomen, thigh; females: tricep, suprailiac, thigh)
downsides of skin fold
Human error in clipping at muscle instead of pure fat
