Answer:

While exercising, the muscles need additional energy as the breathing rate and volume of each breath increase to bring more oxygen into the body and remove the carbon dioxide produced. If insufficient oxygen is available to the muscles, for instance, the exercise is vigorous and/or prolonged, the heart and lungs are unable to supply sufficient oxygen. Muscles begin to respire anaerobically. Lactic acid is produced from glucose, instead of carbon dioxide and water. Muscles continue to contract, but less efficiently. When a period of exercise is over, lactic acid must be removed, because the body's tolerance to lactic acid is limited. These processes require oxygen. This is why, when the period of activity is over, a person’s breathing rate and heart rate do not return to normal straight away.
