Submit report about following topics: ( Note: I don't want handwriting please )

a. Hydrostatic, or underwater weighing.

b. Air Displacement Plethysmography.

c. Neutron Activation Analysis.

d. Total Body Potassium.

Answer 1

A. Hydrostatic weighing, also known as underwater weighing or hydrodensitometry, is one of the most accurate ways to measure body fat. It was considered the gold standard for measuring body composition until more advanced methods, such as CT scans and MRI scans, were developed.

B. Air displacement plethysmography is a recognized and scientifically validated densitometric method to measure human body composition. ADP is based on the same principles as the gold standard method of hydrostatic weighing, but through a densitometric technique that uses air displacement rather than water immersion.

C. Neutron activation analysis is the nuclear process used for determining the concentrations of elements in a vast amount of materials. NAA allows discrete sampling of elements as it disregards the chemical form of a sample, and focuses solely on its nucleus

D. Total body potassium is approximately 55 mEq/kg body weight. Of this amount, 98% is in the intracellular compartment (primarily in the muscle, skin, subcutaneous tissue, and red blood cells) and 2% is in the extracellular compartment.
