The muscle fatigue is most likely due to lack of oxygen and build up of waste in the muscles.

WHAT IS LACTIC ACID FERMENTATION?

Lactic acid fermentation is an anaerobic process whereby living organisms respire without the presence of oxygen.

Lactic acid fermentation leads to the formation of lactic acid, which builds up in the muscle cells and causes a burning sensation.

Therefore, the muscle fatigue experienced by the student is most likely due to lack of oxygen and build up of waste in the muscles.
