Q
What is believed about v02? some say what_____________
A
- Central limitation: VO2max limited by O2 delivery
- Qmax and CaO2
recorded 98% 02 utilization
Peripheral limitation: VO2max limited by O2 extraction
* Diffusion and O2 utilization by the muscle

Q
How does An increased Q effect v02?
A
Cardiac Output (Q)
* VO2 = SV x HR x a-vO2 dif
* Q : how much blood leaves the ventricles each
minute
Bigger ventricles means means stronger heart more 002 delivery
