In order to explore the association of CKMM gene A / G polymorphism with endurance, strength speed, and mixed exercise capacity, the search was performed by searching Superstar Medical Online, Wanfang Database, Weipu Database, China Biomedical Literature Service System, China Knowledge Network (CNKI) , Chinese Science Citation Database (CSCD), EBSCO database, PubMed, Science Direct, and Web of science. Include studies for meta-analysis. The results showed that: CKMM gene polymorphism in endurance athletes,endurance sports ability, speed power and mixed item sports ability. Subgroup analysis based on race revealed that CKMM A / G polymorphic alleles, dominant genes, and heterozygous models in Asian and European populations were significantly associated with endurance performance (P <0.05); outstanding Asian endurance athletes The performance is increased by the G allele, and the outstanding European endurance athletes are increased by the A allele. It can be seen that the CKMM gene A / G polymorphism can be used as an index for selection of Asian and European endurance athletes, but the A: G allele differences of different ethnic groups should be considered.
