Blood measurements of a marathon runner during a marathon race do not show a similar rise in lactic acid levels because he undergoes mostly aerobic respiration.

What are aerobic and anaerobic respiration?

Aerobic respiration is respiration which occurs in the presence of oxygen.

Anaerobic respiration is a respiration which occurs in the absence of oxygen

During aerobic respiration in humans, the end-product is acetylcoA while in anaerobic respiration, the end product is lactic acid.

A sprinter undergoes mostly anaerobic respiration and produces lactic acid, while a marathon runner undergoes mostly  aerobic respiration and produces less lactic acid.

Therefore, blood measurements of a marathon runner during a marathon race do not show a similar rise in lactic acid levels because he undergoes mostly aerobic respiration.
