Work - product of force and the distance through which the force acts W=Force x Distance Measured in Neutonmeters or Joules Power - how much work is accomplished per unit of time P= W/T Measured in Watts Ergometry - Measurement of the work output Example: Bench step in which the participant steps up and down on a bench at a specified rate -Erogemter, treadmill, cycler Calorie - amount of heat required to raise the temperature of one gram of water by one degree Celcius Direct ca...

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...
