Which body composition method gives a regional breakdown of bone mineral, fat mass, and lean mass using low-dose X-rays?
Answer: DEXA (dual-energy X-ray absorptiometry)
DEXA scans separate bone, fat, and lean tissue by body region.
A client gets a much higher body fat reading on a bioelectrical impedance scale after a hard workout without drinking water. What explains this?
Answer: Dehydration changes how electrical current moves through the body
BIA depends on body water, so dehydration raises impedance and inflates the body fat estimate.
Skinfold calipers estimate body fat by measuring:
Answer: The thickness of subcutaneous fat at specific sites
Calipers measure folds of skin and the fat just under it, then put the readings into prediction equations.
Which equipment directly measures VO2max during a graded exercise test?
Answer: A metabolic cart that analyzes expired gases
A metabolic cart measures the oxygen and carbon dioxide in exhaled air to calculate oxygen uptake directly.
A strength coach uses force plates during countermovement jump testing mainly to measure:
Answer: Ground reaction forces and rate of force development
Force plates record how much force is applied to the ground and how fast it is produced.
A portable blood lactate analyzer is most commonly used by endurance coaches to:
Answer: Find lactate threshold for setting training zones
Lactate samples taken at rising intensities show the threshold used to set training zones.
Which tool is used to measure joint range of motion in degrees during a movement screen?
Answer: Goniometer
A goniometer is a protractor-like tool that measures joint angles.
