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.
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.
