hyperventilation and blood lactate


Recommended Posts

I understand that hyperventilation increases the rate of CO2 leaving the body causing the blood to become more basic. During anarobic exersize lactic acid is produced, so i was wondering if they have an affect each other if done at the same time? I have googled all sorts of things related and no luck.

I looked up metabolic acidosis on wikipedia, and they had a link to lactic acidosis, which is what you are looking for:

Also take a look at:

 

http://en.wikipedia.org/wiki/Respiratory_alkalosis

 

<speculation>

One of the symptoms they list is deep, heavy breathing, suggesting that the two do affect each other. Considering that the anaerobic systems can generate energy faster than aerobic systems (i.e. one can sprint faster than they can distance run), I would think that the lactic acid will be produced faster than the CO2 can be blown off.

one equation can explain it best:

 

CO2 + H2O <=> H2CO3 <=> H+ + HCO3-

 

respiratory acidosis more CO2, equilibria shift to the right, high [H+], pH of blood reduced (acidosis),

 

respiratory alkalosis less CO2, equilibria shifts to the left, reduced [H+], pH of blood increased (alkalosis)

 

metabolic alkalosis increased [HCO3-], equilibria shifts to the left, reduced [H+], pH increased (alkalosis)

 

metabolic acidosis reduced [HCO3-], equilibria shifts to the right, increase [H+], pH decreased (acidosis)

 

to answer the original question:

 

during anaerobic exercise you have a mild form of respiratory acidosis due to increased CO2 in being carried in the blood... the change in pH is detected the body and then body then counteracts this mild acidosis by increasing the removal of carbon dioxide... you could also counteract respiratory acidosis by increasing HCO3- levels into the blood... one way this could be done by giving a sodium biocarbonate (NaHCO3) injection...

 

hope that is clear...
