Which acid buildup is associated with strenuous exercise and massage?

• A. Lactic acid
• B. Uric acid
• C. Citric acid
• D. Sulfuric acid

Answer: (A)

During intense effort, the muscles often work faster than oxygen can be supplied, so they rely on anaerobic glycolysis. Pyruvate is converted to lactate, and this process releases hydrogen ions that lower the muscle pH. That buildup of acidity, often called lactic acid, contributes to the burning sensation and fatigue you feel during strenuous exercise. Massage helps by increasing blood and lymphatic flow, which aids the removal of metabolic wastes like lactate from the muscles and can reduce swelling, supporting recovery. The other acids listed aren’t the immediate byproducts of this exercise stress: uric acid comes from purine breakdown, citric acid is part of the normal citric acid cycle inside cells, and sulfuric acid isn’t a typical muscle metabolite in this context. So the acid buildup linked to strenuous exercise and massage is lactic acid.
