Taurine can regulate neurotransmitters and keep the central nervous system in a good stress state. Taurine can increase and stabilize the concentration of branched-chain amino acids in the body, which has a positive effect on maintaining muscle movement. Branched-chain amino acids can compete with aromatic amino acids, inhibit the transport of aromatic amino acids to the brain, interfere with the normal function of central dopamine and adrenergic nerve conduction pathways, and delay central fatigue.

Exercise-induced fatigue is related to the generation of intracellular free radicals and the increase of lipid peroxidation. More than 75% taurine in human body exists in skeletal muscle. A large number of studies show that exercise can increase the production of free radicals, enhance lipid peroxidation and damage tissue cell membranes. Supplementing antioxidants can inhibit this change and improve exercise ability.

Taurine is a sports nutritional supplement. Taurine can reduce lipid peroxidation products produced during exercise and promote the increase of antioxidant enzyme activity after exercise.

Taurine supplementation can improve athletes' sports ability, which is related to anti-free radical damage.
