Abstract: As the hot topic target gene of research on sports ability genetics, ACTN3 R577X polymorphism’s correla-tion with excellent speed and strength qualities has been widely confirmed. But besides that, research on the other physiological effects of this polymorphism has not been widely developed in China for many years. The author gave an overview of the main results of international research on the correlation between R577X polymorphism and other sports phenotypes (sports adaptation, sports recovery and sports injury risk) as well as body aging so far, so as to pro-vide reference for developing related research in China, and to provide a new perspective for the individualized imple-mentation of sports training programs and the individualized prevention and treatment of aged diseases in the future.
