FM stands for?
Fat mass
Archimedes
Law of similitude
Law of buoyancy (body composition)
True
FFM stands for
Fat free mass
Densitometry: basic assumptions Body consists of 2 compartments Fat mass & fat free mass Density of FM =0.90 g/ml Density of FFM is approx 1.10g/ml
True
How do we determine density?
Density =mass/volume
What does a water displacement tank measure?
The volume of water displaced
Bod pods measure the?
Volume of air displaced
Fat people float, lean people sink
True
What is the law of buoyancy?
Weight of liquid displaced
Underwater weighing
Density=mass/volume
Volume=(Wt air-Wt water)
Density=mass/ (Wt air- Wt water)
Wt stands for weight
True
Density=mass/volume
Volume= (Wt air - Wt water) / water
(Minus the entrapped volumes in the lungs and GI tract)
True
