Hi, its because there's an absence of O2 (oxygen debt) and glucose (partially broken down) to the muscles due to the vigorous exercise and because of this insufficient amounts of energy are produced for the muscles to use, so the body undergoes anaerobic resp as it keeps the muscles going so that at least some useable amount of energy is made instead on no energy. A by product of anaerobic resp is Lactic acid which builds up in the muscles too and causes the aches and pains you get because of the changes in Blood pH. Hope this helps.
