What is Lactic Acid

How Muscles Produce Lactic Acid?

Human bodies burn energy during the day in the presence of oxygen. Most of the energy is produced from the breakdown of sugar through glycolysis. The end product of this process is pyruvate, which is utilized by the body to generate even more energy. When you work out harder, muscles will require more energy to operate. As a result, pyruvate will be gradually converted into lactic acid. This waste product subsequently goes into the bloodstream and causes muscles to become painful and sore. Many people often mistake that muscles only generate lactic acid when there is a lack of oxygen. However, this is not actually true in most cases. Muscles can get a lot of oxygen, but the production of acid lactic can help produce energy much quicker during strenuous exercises. [2]
