β-Alanine is a Group A sport nutrition supplement according to the ABCD classification system (2021 edition) of the Australian Institute of Sport (AIS). The research results have shown that β-alanine supplementation of 1.6-6.4 g per day for 2-24 weeks can increase the concentration of carnosine in the muscle to maintain the pH balance, anti-oxidation, and increase the sensitivity of calcium ion. It is more conducive to the maintenance of high-intensity exercise and fatigue recovery. The relevant studies have also shown that combat sports are high-intensity interval training, and β-alanine is used in boxing, judo, taekwondo, and wrestling. The supplementary benefits for different types of combat sports are to achieve the improvement of sports ability indicators and performance. β-Alanine can also maintain the anaerobic metabolism and repeated sprint ability of elite athletes to be a key factor in sports performance. The physical and mental stress faced by athletes before the competition and the fatigue during the competition affect cognition and emotion. The relationship between β-alanine supplementation and brain cognitive ability and emotion has been confirmed in animal experiments, but no consistent conclusions have been reached in human studies. By understanding how β-alanine supplementation is applied to combat sports, and it further affects the sports performance, brain health, cognitive function, and physiological response of combat athletes. β-Alanine supplementation can be used to conduct more in-depth investigations in athletes in the near future.
