Lab 3 - Exercise Thresholds Flashcards
1
Q
What is the lactate threshold?
A
- highest metabolic rate where blood lactate concentrations
2
Q
What is the respiratory compensation point?
A
- metabolic rate at which body can no longer buffer the H+ ions associated with increase in CO2 and lactate concentration in blood
3
Q
What is the standard non-invasive estimator of lactate threshold when looking at the graphs?
A
- in the VCO2 graph, the point at which there is a change in slope is where the lactate threshold is
4
Q
What is PetCO2
A
- end tidal pressure CO2
5
Q
What is PetO2
A
- end tidal pressure O2
6
Q
What is Ve?
A
- minute ventilation
- total volume of air that is exhaled each minute
