\nMuscle fatigue during strenuous exercise is primarily associated with the accumulation of lactic acid.
\n<\/section>\n
\nWhen muscles undergo intense activity with insufficient oxygen supply (anaerobic respiration), glucose is broken down into pyruvate, which is then converted into lactic acid. The build-up of lactic acid in muscle tissue lowers pH and interferes with muscle contraction mechanisms, leading to a burning sensation and fatigue.
\n<\/section>\n
\nWhile other factors like depletion of energy stores (ATP, glycogen), ion imbalances, and central nervous system fatigue also contribute to overall fatigue, lactic acid accumulation is a significant factor in muscle fatigue during anaerobic work. Cholesterol and triglycerides are types of fats, and lipoic acid is an antioxidant coenzyme; none of these are directly responsible for the acute fatigue caused by intense muscle exertion.
