- What is VO2 max?
- Maximum volume of O2 exchange that can be accomplished by a particular individual
- What does V02 represent?
- Volume of oxygen consumed ---Indicator of fitness
- How is it influenced with training?
- VO2 Max increases with training
- What is the difference between absolute and relative VO2?
-
Relative accounts for body weight
5L/min Absolute
38 ml/kg/min relative - What is the relationship between V02 and kcals?
-
Burn about 5 kcals per ml/min of o2 consumed/min
Conversion is approx
5 kcal /liter O2
vo2 max to calories > > vo2 max X 5 = kcals (Approx)
ie 2.5 ml O2/min X5 + 12 Kcals/min ( at max ) - What is RMR?
- Resting Metabolic Rate
- What is a MET?
- Metabolic Equivalent MET= 3.5mLO2/kg/min
- Name I field test used to assess the immediate energy systems.
- Vertical jump
- What intensity would Free Fatty acids supply the greatest quantity of fuel for exercise?
- Low
- What intensity would muscle glycogen supply the greatest quantity of fuel for exercise?
- High
- What supplies energy during the 02 deficit stage?
- Fast glycolysis (Lactate cycle)
- What does EPOC represent?
- Excess Postexercise o2 Consumption
- How does training influence 02 deficit and EPOC?
- Recover faster
- What effect does high intensity training have on CP, ATPase, PFK, and glycogen breakdown?
- Minimal
- What effect does endurance training have on mitochondria, fatty acid use, and enzyme activity of Krebs or beta oxidation?
- Increase Krebs capacity, Increase number and size of mitochondria, increase transport mechanisms for FFA.
