Densitometry (underwater weighing)
, Which body weight evaluation way is the least effective? Right Ans -
Skinfold Measurements
What is the Fat Distribution Pattern? Right Ans - Measured by waist to hip
ratio and waist circumference:
Apple-Shaped fat patterning -upper body
Pear-shaped fat patterning -lower body
Which fat distribution pattern has increased health risks? Right Ans - Apple
shaped fat patterning
What is the Basal Metabolic Rate? Right Ans - Energy expended to maintain
basal, or resting, functions of the body.
How does BMR increase? Right Ans - more lean body mass, during stress,
and periods of growth (childhood and pregnancy)
How does BMR decrease? Right Ans - older age and during energy
restriction (fasting or starvation)
How much does BMR contribute to "energy expenditure" ? Right Ans - 2/3
or 60-70%
