Swimming, running, and basketball use the lactic acid system.
The Glycolytic System produces lactic acid
Lactic acid fatigue.
As Lactic acid is formed from glucose, it is produced in the stomach of the digestive system
Most team games use the lactic acid system. However, this is more common in Invasion games.
Lactate (also known as lactic acid) and NAD+
The lactic acid energy system relies on the breakdown of glycogen to produce energy. As it does not require oxygen to break down glycogen a by-product called lactic acid is formed. If enough lactic acid is accumulated then the body begins to fatigue. To recover, the lactic acid requires oxygen. Once oxgen is present the lactic acid can be converted back to pyruvic acid which can once again be used to produce energy. Therefore to speed up recovery of the lactic system an "active"recovery at a low intencity is recommended. This then employs the use of the aerobic energy system which requires oxygen to be transported to the working muscles, and at the same time removing the fatiguing lactic acid.
acid as in lactic acid?
Every sport uses the lactic acid system. Lactic acid is the fluid that builds up in your body after a workout. Build-up of lactic acid isn't harmful, but it is the fluid that makes your body sore/tired after a workout. A good, quality cool down will prevent some of this soreness. Try slow jogging, walking, or stretching after your workout.
Anaerobic Respiration.
Lactic acid has two optical isomers: L-lactic acid and D-lactic acid.
Lactic acid (or lactate, which is the anion of lactic acid) is the product of lactic acid fermentation.
