Answer:
lactic acid fermentation
Explanation:
Muscle derive energy in form of ATP by aerobic cellular respiration for their contraction. However, continuous physical activities deprive the muscles of oxygen. The process of lactic acid fermentation does not require the presence of oxygen to occur.
Therefore, in the absence of oxygen, lactic acid fermentation occurs in muscles to serve as a quick source of ATPs for muscle contraction.
