Measurements Chapter 1 Test Questions
and Answers
How do we measure energy, oxygen consumption, heart rate and multiples of resting
metabolic rate? - Answer-we exercise oxygen consumption VO2 Max by absolute (not
relating to body mass) and relative (respective of body mass)
What's the difference between absolute and relative VO2? - Answer-Absolute VO2 is in
not in relation to body mass and uses the unit Liters/Minute while Relative VO2 is in
retrospect to body mass, using the unit Mililiters of O2/Kilogram/Minute
What is a MET? - Answer-The Metabolic Equivalency is the amount of O2 consumed by
every kilogram of Body Weight every minute
What is the value of METS? - Answer-1 Met = 3.5 mL O2/kg/min

What is a kilocalorie? - Answer-Another measurement of energy
What is a kilocalorie measured to? - Answer-raising 1000 g (1kg) of H2O 1 degree
celsius
How do you measure a true energy expendenture? - Answer-Calorimetry
What are two types of Calorimetry? - Answer-Direct and Indirect
What is direct Calorimetry? - Answer-it is the measurement of heat production as an
indication of metabolic rate
What is the equation for direct calorimetry? - Answer-Foodstuff + O2 >>> ATP + Heat
What is indirect calorimetry? - Answer-it is a measurement of oxygen consumption as
an estimate of resting metabolic rate
What is the equation for indirect calorimetry? - Answer-Foodstuff + O2 >>> Heat + CO2
+H2O
What's the difference between indirect and direct calorimetry? - Answer-direct
calorimetry includes CO2 and H2O and use of expensive laboratory equipment
