Answer 27

estimating body composition, %body fat | electric current flows throughout the body

Question 28

BodPod

Answer 28

uses pressure and volume to determine body composition | body density

Answer 29

the ability of the circulatory and respiratory systems to supply oxygen to the muscles to perform dynamic physical activity indicator of functional capacity of heart, lungs, and body

Question 30

aerobic fitness test

Answer 30

VO2 max (L/min) or (mL*kg/min)

max exercise performance | sub max exercise performance

Question 34

max exercise performance

Answer 34

more accurate voluntary exhaustion open-circuit computer calculations

Question 35

submaximal exercise performance

Answer 35

``` less accurate but more practical VO2 based on HR slope 1) HR increased as O2 usage increased 2) VO2 reached max HR 3) less fit will have a higher HR ```
