Lactate and Injury

While I’ve discussed lactate in relation to its role in the production of energy, lactate can stimulate other activities—especially related to recovery and healing. For example, collagen production, used for physical repair of the body, can double after a workout with rising lactate levels. Physical wounds also produce lactate, accumulating it for healing. Lactate may also promote healing in other ways, by increasing oxygen supply and blood flow to the area. And lactate can even stimulate the production of new blood vessels when necessary. Lactate stimulation following wear and tear, and injury, may also be stimulated by adrenal stress hormones.

The complex physiology of lactic acid and lactate metabolism is still unraveling. In the coming years, new research will reveal even more.
