Term
| Oxygen Deficit, and what does it suggest? |
|
Definition
the lag in oxygen uptake at the beginning of exercise.
Suggests anaerobic pathways contribute to the total ATP production, and after steady state, it's met through aerobic ATP production |

Definition
| oxygen debt and oxygen deficit. |

Term
| Factors that contribute to EPOC |
|
Definition
1. Resynthesize stored PC in muscle
2. replace O2 stores in both muscle and blood
Slow Portion of EPOC:
1.elevated body temp
2.O2 required to convert lactic acid to glucose (gluconeogenisis)
3. elevated blood levels of epinephrine and norepinephrine |

Definition
Debt: aka EPOC is the oxygen consumption above rest after exercise
Deficit: Lag in oxygen uptake at beginning of exercise
|
|
|
Term
| Define and when does an O2 drift occur? |
|
Definition
Not reaching a steady state during prolonged exercise because of hot/humid environment or exercise at a high relative work rate >75% VO2max
|
|
|
Term
| Oxygen uptake increases in a linear fashion during incremental exercise until what? |
|
Definition
|
|
Term
| Respiratory exchange ratio |
|
Definition
VCO2/VO2...aka RQ
Carbon dioxide output/oxygen input |

|
Term
| Why does fat oxidation require more oxygen that carbs? |
|
Definition
| Because carbs contain more oxygen to begin with |
