Lab 3: Anthropometry Flashcards
What is the BMI used for? What does it indicate? What does it do not measure?
measure the health fitness and obesity of person
the risk of premature death due to cardiovascular disease
fat body percentage
The BMI range
Underweight: <18.5
Normal: 18.5-24.9
Overweight: 25 - 29.9
Obesity: >30
Advantage/Disadvantage of hydrostatic weight?
gold standard using Archimedes principles
Accurate
Expensive/ Time consuming/ Uncomfortable
Advantage/Disadvantage of DEXA (dual X-ray absorpmetry)
give bone/ muscle mass percentage
second accurate/fast
expensive
Advantage/Disadvantage of Bod Pod
sitting in chamber and breathe
accurate
expensive/ timely/ uncomfortable
What does BIA do? Advantage/Disadvantage of BIA (bioelectrical impedance)
measure the electrical resistance of current in body (fat is poor conductivity)
Fast/ Inexpensive
Inaccurate due to the hydration/ bent over and woman has higher % fat on top than man
Advantage/Disadvantage Skin-fold measurement? What is device for this?
Cheap/ Accurate in high correlation 0.7-0.9 to hydrostatic weighing
require experience
fat caliper
What does girth-measurement measure? Advantage/Disadvantage
the circumferences at predetermined location (waist-to hip ratio) -> the % body fat distribution and risk of premature death of CAD
Fast/ Inexpensive/ easy
Inccurate
Advantage/Disadvantage of height and weight table?
simplest
inaccurate because doesn’t take into account of body frame and body mass
