  • What happens when muscles get tired?

    Q: What happens when muscles get tired?

    A: According to Gatorade Sports Science Institute, muscles hurt when they tire due to the accumulation of lactic acid. Muscles produce energy by converting glycogen into adenosine triphosphate with the release of acid and carbon dioxide. Muscles tire quickly during heavy exercises causing a demand for more energy. When the amount of oxygen supply to exercising muscles is limited, aerobic respiration takes place, resulting in an acidic environment within muscle fibers.
