Q
Respiratory quotient is measure at the…
A
Muscle level- by arterio-venous balance (blood samples)
1
Q
Respiratory quotient=
A
CO2 eliminated / O2 consumed
2
Q
RER=
A
CO2 expired / O2 uptake
3
Q
RER carbohydrate oxidation:
A
6 O2 + C6,H12,O6 —-> 6 CO2 + 6 H20 + 32 ATP
4
Q
RER fat oxidation:
A
C16,H32,O2 + 23 O2 —-> 16 CO2 + 16 H2O + 129 ATP
5
Q
Fick equation:
A
VO2max= Qmax x D(a-v)O2max
6
Q
Ventilation rate (VE, L/min):
A
Respiratory rate (breathes/min) x Tidal volume (L)
7
Q
Letter representing cardiac output:
A
Q
8
Q
a-vO2 difference does what during exercise?
A
Increases, more O2 extracted from arterial blood
9
Q
Aerobic exercise training increases:
A
Enzyme activity - capillary density - muscle mitochondria
