Lab Test 2 (lab 5) Flashcards
Two names for UWW
underwater weighing
hydrostatic weighing
UWW is this type of model
2 compartment model
what are the two compartments
fat weight / fat-free weight
T/F: UWW is the gold standard and criterion method(measure)
T
UWW is the best method yet to do this
measure body composition
standard error of estimate for UWW
+or- 2%
Three types of anthropometric measurements
skinfolds
circumferences
diameters
Benefits of anthropometric measurements
portable
standard error of estimate for anthropometric measurements
+ or - 5%
Why measure body comp 3
health implications
body weight recommendations
describe populations
T/F: risk of diabetes often exhibits unique fat distribution
T
must know body comp factors to accurately and safely make body weight recommendations, athletic or otherwise is an example of
why measure body composition
what is a major drawback of body weight recommendations that are made using height and weight tables
do not consider FFW vs FW
Why would you want to use body comp to describe populations
determine risk factors for ethnic groups, sexes.
Determine body comp of athletic populations
fat component of UWW is composed of this
adipose and neural tissue
two basic forms of adipose tissue
subcutaneous
intermuscular and/or intravisceral
density of FW
0.90 g/ml (kg/L)
This is defined as collective term consisting of bone, muscle, tendons, viscera, connective tissue, etc
FFW or FF component
