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 Mililiter...

Direct calorimetry - process of measuring a person's metabolic rate via the measurement of heat production -direct measurement of metabolic rate Indirect calorimetry - direct relationship between O2 consumed and amount of heat produced -O2 consumption, CO2 production, N2 balance Oxygen deficit - -a lag due to slower activation of oxidative pathways -difference between oxygen uptake in the first few min of exercise and after an equal time period of steady state What is the steady s...

explain the 2 ways energy expenditure is measured correct answers 1. direct calorimetry: measures the heat your body produces, uses calorimeter chamber 2. indirect calorimetry: measures the oxygen you us and breathe out (VO2 = VE x (FIO2 - FEO2) explain what is involved with open-circuit spirometry and when you would use it correct answers - breathing in air from the room, breathing out through a different system - metabolic cart - computer - mixing chamber: collects expired gas - gas an...
