Answer:

hi

this is a nice questions

ok so here is the answer

while a sports man is running he breathes heavily as his stamina decreases

=> so the demand of oxygen is less for him

=>now he stars breathing anoerabically

=>during this  The muscles begin to do anaerobic respiration, because oxygen is not present.

=>now lactic acid gets accumalted in the muscles.this process is  lactic acid fermenation
