Test Evaluation Technologies: Bioimpedance, Plicometry and DEXA
Agenda
QUESTION 1: What anthropometric tool is used to pinch localized adiposity?
Plicometer or metal caliper
Bioelectrical impedance platform
DEXA scanner
Hydrostatic weighing
2nd QUESTION: What variables are included in the predictive equations of folds?
Fold thickness only
Sex and age of individual
Body hydration
Bone density
3rd QUESTION: What is the main limitation of plicometer measurements mentioned?
Margin of error due to technical expertise
Radiation exposure
Sensitivity to hydration
High operating cost
4th QUESTION: What can cause a slight dehydration before a bioelectrical impedance?
Underestimation of fat percentage
Increase muscle mass
Identical measurements to the real ones
Overestimate fat percentage
5th QUESTION: Why does lean muscle conduct electricity better?
Because you have more fatty acid
Because it is rich in water and salts
Because it contains more bone
Because it is less dense
QUESTION 6: Which two methods are described as elite for clinical accuracy?
Bioelectrical impedance and plicometry
Conventional scales and plicometers
Commercial platforms and calipers
DEXA scan and hydrostatic weighing
7th QUESTION: What does the DEXA scanner measure according to the text?
Speed up the speed of the electric current
Thickening of skin folds
Bone density muscle fraction and adipose volume
Floating in a tank
8th QUESTION: Why are DEXA and hydrostatic weighing reserved for scientific tests?
Because of its immediacy
Because of its ease of use
Due to its operational complexity and high cost
Because they are portable
