Q. How can the knowledge about fermentation describe the origin of muscle cramps and pains after intense physical exertion?
A typical fermentation process due to oxygen scarcity happens in the muscle tissue under intense use muscles demand too much energy (ATP) and consume much more oxygen to produce that energy a high consumption leads to oxygen scarcity and the muscle cells begin to make lactic fermentation trying to satisfy their energetic needs. In this situation muscle pain, fatigue and cramps are due to the lactic acid released by fermentation.
