(2) Fat mass/lean body mass
(3) Muscle mass
(4) Skeletal mass
(5) Other components i.e. total body water
What is the difference between hypertrophic and hyperplastic obesity?
Hypertrophic = increased size of fat cells
Hyperplastc = increased number of fat cells (progression from hypertrophic)
What is hypertrophic obesity?
Increased size of fat cells
What is hyperplastic obesity?
Increased number of fat cells
Whay assess body composition? (3 things)
(1) Assess the "quality" of a subjects weight
(2) Assess physical changes associated with nutrition, training and lifestyle interventions

The form or structure of the body (muscularity, linearity and fatness)
How is body size determined?
By height and weight
What is body composition?
A chemical composition of fat mass and fat free mass.
Whats the difference between a direct method of body composition and an indirect method?
Direct method involves disecting a cadaver and obviously can't be done in vivo.
Indirect methods are done in vivo.
Explain the validity of direct and indirect methods.
Indirect methods are developed from direct methods, doubly indirect methods are developed from indirect methods and are therefore more prone to errors in calibration.
