Cori cycle. The Cori cycle (also known as the lactic acid cycle), named after its discoverers, Carl Ferdinand Cori and Gerty Cori, [1] is a metabolic pathway in which lactate, produced by anaerobic glycolysis in muscles, is transported to the liver and converted to glucose, which then returns to the muscles and is cyclically metabolized back to lactate.
Lactoylphenylalanine, or Lac-Phe, is a metabolite generated by intense exercise. [1] [2] [3] In mice, high levels of Lac-Phe in the blood cause a decrease of food intake [1] and in humans, its production has been shown to correlate with adipose tissue loss during an endurance exercise intervention. [4]
Excess post-exercise oxygen consumption (EPOC, informally called afterburn) is a measurably increased rate of oxygen intake following strenuous activity.In historical contexts the term "oxygen debt" was popularized to explain or perhaps attempt to quantify anaerobic energy expenditure, particularly as regards lactic acid/lactate metabolism; [1] in fact, the term "oxygen debt" is still widely ...
Undissociated lactic acid can cross the rumen wall to the blood, [29] where it dissociates, lowering blood pH. Both L and D isomers of lactic acid are produced in the rumen; [24] these isomers are metabolized by different metabolic pathways, and activity of the principal enzyme involved in metabolism of the D isomer declines greatly with lower ...
For example, exercises that are performed at maximum rates for between 1 and 3 minutes depend heavily upon the lactic acid system. [1] In activities such as running 1500 meters or a mile, the lactic acid system is used predominantly for the "kick" at the end of the race. [4]: 11–12
The soreness usually disappears within about 72 hours after appearing. If treatment is desired, any measure that increases blood flow to the muscle, such as low-intensity activity, massage, nerve mobilization, [15] hot baths, [16] [17] or a sauna visit may help somewhat. [11]: 112

Static stretching is the appropriate form of stretching to aid in the cooling down procedure. It aids in decreasing the body's temperature, removing lactic acid from the muscles and increasing flexibility. [5] Each stretch should be held for a minimum of 10–20 seconds and stretched to the point of mild discomfort but not pain. [7]
