Question

after a vigorous excercise or work we feel pain in muscles .what is relation ship between pain and respiration

Answer 1

Respiration means the breakdown of glucose into energy.
Respiration is of 2 types:-
1) Aerobic- Breakdown of glucose with oxygen that releases more energy.
2) Anaerobic-Breakdown of glucose without oxygen that releases less energy.

After a vigorous excercise or work we feel pain in muscles as our muscles do Anaerobic respiration as we need more energy to exercise but we don't have more oxygen. This type of respiration releases ethyl alcohol which causes pain in our muscles.
