Applied Metabolism Flashcards
What is Applied Metabolism?
The estimation of fuel utilization & energy cost
What percentage of ATP potential energy is recovered, and what is done with the remaining amount?
34% ATP; the rest is converted into heat = Caloric expenditure
When measuring heat loss or gain, what are the four methods used?
Convection (circulating), Conduction (moving; skin), Evaporation (to air), and Radiation (absorbed energy)
To perform exercise (work), requires _______.
Energy
Every increase in _____ should increase ______ & ______. Thus, there is a ______ relationship between O2 consumption & work.
Work; ATP; Oxygen
Define O2 Uptake and what it’s purpose is.
Capacity to transport & utilize O2; effects ability to maintain work.
Define VO2 max and how the O2 values are expressed.
Maximal amount of O2 that can be attained during incremental exercise; values expressed relative to body weight (ml/kg/min)
What is the point at which O2 consumption fails to rise despite increased power output and energy demand?
Plateau
What do MET and CRE stand for, what which one determines how fit someone is?
Metabolic equivalent to Rest = MET
Cardio Respiratory Endurance = CRE
CRE determines fitness
Complete this sentence:
“Before you determine energy cost of exercise, ……”
you must estimate VO2 used.
What is the Fick-Principle?
A relationship between HR, Heart Function & Exercise Intensity.
What is the difference between Central and Peripheral Adaptations?
Central = deals with Heart & Lungs Peripheral = deals with Muscles
What is the Respiratory Exchange Ratio?
States O2 need & CO2 productions differ depending if CHO or Fat is oxidized
What is the purpose of Caloric Equivalents?
Used to estimate energy production and determine the contribution of calories from carbs & fats
