Using an insulated, airtight chamber with walls containing copper tubing which water is
passed to asses total body energy expenditure is called
direct calorimeter
Indirect calorimetry is a technique for metabolic rate measurement and involved the
measuring of
metabolic oxygen consumption
The respiratory exchange ration (RER) is defined as the ratio between the
____________________________.
amount of CO2 released and the amount of O2 consumed during metabolism
Calculating kcal/day can be accomplished by _______________________.
liters of O2 consumed per day times kcal used per liter of O2
Basal metabolism is the minimal 240hour energy expenditure for ______________.
basic body functions
Increases with increased body temperature
BMR
The best indicator of cardiorepiratory endurance is
VO2 max treadmill test
Lactate threshold is defined as that point in time during exercise of ____________
intensity when the rate of lactate production ____________ the rate of lactate
_______________ or ____________.
increasing, exceeds, clearance, removal
Lactate threshold is a good predictor of _____________
