6.What is the valid direct measure of MAP or VO2
ANS A breath by breath analysis whereby the subject is hooked up to an
analyzer via a hose/mask. Thew contents of each breath is then
analyzed while incrementally increasing the WR/WL until the subject
can no longer maintain the intended intensity minimum or the tester
deems them unfit to continue.
7.What are METs
ANS A MET or Metabolic Equivalent is the ratio of energy consump- tion
to a reference metabolic rate set by convention to 3.5 ml O2/kg/min.
8.What are the METs during light intensity, moderate intensity, vigorous
inten- sity, and moderate-vigorous intensity PA
ANS Light: >1.5 MET <3.0
Moderate: 3-6 METS
Vigorous: >6 MET
Mod-Vig: All Activities > 3 METs
9.Define Muscular Strength
ANS Is the ability to prodiuce maximal force at a given speed.
