What is lactic acid?

Category: Exercise & Fitness


During exercise, glucose is used to create energy for muscles. If you are performing an aerobic workout and receiving all of the oxygen needed to sustain the action, the resulting effects are carbon dioxide and water. However, if you are performing an anaerobic workout using short bursts of explosive energy and can’t get the required oxygen, lactic acid will begin to accumulate in your muscles. Lactic acid is a by-product of metabolizing glucose and also a waste product that causes a burning sensation in the muscles. So in essence, lactic acid is another form of energy that your muscles need during strenuous and intense training sessions.
