When is anaerobic glycolysis used

Virtually all tissues have a requirement for glucose to function normally. Glycolysis is the major pathway of glucose metabolism and occurs in the cytosol of all cells. It can occur aerobically or anaerobically depending on whether oxygen is available. This is clinically significant because oxidation of glucose under aerobic conditions results in 32 mol of ATP per mol of glucose.

Sports with Dominating Anaerobic Glycolysis System: The anaerobic glycolysis system is the dominant energy system in the following sports: Athletics: m dash. Cycling, BMX events. Football soccer. Gymnastics: acrobatic events all events. Hockey ice. Rugby 7. Skating : Speed skating m, m, m.

The lack of oxygen results in a cellular paucity of oxidized NAD. In order to regenerate NAD, the enzyme lactate dehydrogenase converts pyruvate to lactate.

NADH is oxidized in the process. Lactate may diffuse out of the cell and pass to the liver where it is transformed into glucose; glucose is then capable of passing back to peripheral cells in order to re-enter glycolysis. Lactate actually helps performance during intense exercise. If a muscle cell becomes too acidic the muscle stops functioning as the enzymes that control glycolysis struggle to function in an acidic environment.

The lactate is then quickly removed from the muscle cell, protecting the cell from becoming too acidic so exercise can continue for a little longer. When this happens we are unable to sustain the intensity of exercise and have to either cease exercise or reduce the intensity.

This is why even with the help of lactate we can only work at a high intensity for short periods of time. Training this system is aimed at increasing tolerance to lactate, the removal of lactate and improving the rate at which glycolysis produces ATP. If you want the system to completely recover and clear the majority of accumulated lactate so you can repeatedly condition it you would use a ratio of 6 seconds of rest for every second of work.

A ratio of can be used to create a greater lactate response and carry some of the fatigue into the next set of repeats. This helps to condition the body to clear get rid of lactate. This forces the person to continue to exercise with a lot of lactate present thus dramatically increasing their ability to tolerate the exercise.
