Body Density - The weight of molecules present in a certain volume.
D= Mass (kg)/Volume (m^3)
Archimedes' Principle - The buoyant force on an object is equal to the weight of the fluid displaced by
the object. An object heavier than the water it displaces will sink, lighter will float. Can be used to
calculate body fat %.
Underwater weighing (hydrostatic) - Measure of body composition by expelling all air from lungs and
then being weighed. Extremely accurate.

Oxidizing Agent - substance being reduced or gaining electrons
doubly labeled water - a measurement technique for determining energy expenditure over a long time
period using radioactively labeled hydrogen and oxygen. serves as "gold standard" that can be
converted into RQ. **Urine samples
Wingate Test - anaerobic power test to evaluate maximal rate at which glycolysis can deliver ATP. is a
cycle test of anaerobic leg power, conducted over 30 seconds.
Methods for assessing HR - Electrocardiogram (ECG): imaging test that takes 15-20 minutes and may
help diagnose cardiac diseases. Manual Palpation: Carotid pulse (neck), radial pulse (wrist), brachial
pulse (near inner elbow *BP)
Bradycardia vs. Tachycardia - Bradycardia: <60 bpm resting HR
