THE LACTATE CONCEPT

Gladden, L. B., Spriet, L. L., Donovan, C. M., Bonen, A., & Brooks, G. A. (1997). The role of skeletal muscle in lactate exchange during exercise. Medicine and Science in Sports and Exercise, 29(5), Supplement abstract 424.

"Lactate is not simply a dead-end metabolite which is produced in skeletal muscle in response to hypoxia. Instead, lactate is produced by many tissues under many different conditions, transported throughout the body, and taken up and metabolized by many tissues. This 'lactate shuttle' necessarily involves lactate metabolism and the membrane transport of lactate, especially in skeletal muscle. Historically, skeletal muscle was viewed as a producer of lactate; however, skeletal muscle (both at rest and during exercise) is now known as not only a major source of lactate, but also as the most important consumer of lactate." (p. S74)
