Abstract :Objective: Adrenergic receptors have a critical role in regulating neurotransmitter release from sympathetic nerves and adrenergic neurons in the central nervous system. The rs1800544 polymorphism in 3’-untranslated region of ADRA2A is caused by C-1291>G nucleotide change. In this study, we aimed to analyze the rs1800544 distribution in kickboxing players. Methods: A total of 12 male players and 101 sedentary individuals insert ignore into journalissuearticles values(as a control group); participated in the study. Following DNA isolation, rs1800544 polymorphism of ADRA2A was determined by real-time polymerase chain reaction insert ignore into journalissuearticles values(Rt-PCR);. Statistical analysis was carried out by chi-square test. Results: CC, CG and GG genotypes and percentages for rs1800544 polymorphism were analyzed as 5 insert ignore into journalissuearticles values(41,7%);, 4 insert ignore into journalissuearticles values(33,3%); and 3 insert ignore into journalissuearticles values(25%);, respectively. C allele was counted as 14 insert ignore into journalissuearticles values(58,3%); and G allele as 10 insert ignore into journalissuearticles values(41,7%);. In the control group CC, CG and GG were found as 34 insert ignore into journalissuearticles values(33,6%);, 53 insert ignore into journalissuearticles values(52,5%);, 14insert ignore into journalissuearticles values(13,9%);, respectively. C allele was counted as 121 insert ignore into journalissuearticles values(60%); and G allele as 81 insert ignore into journalissuearticles values(40%);. When we compare athletes and controls in the terms of genotypes, we detected no statistically significant difference insert ignore into journalissuearticles values(p>0,3940);. For the allele comparison, we detected no significant difference between groups insert ignore into journalissuearticles values(p>0,0871);. Conclusion: Determination of gene combinations in Turkish athletes is of great importance for carrying out of these studies. Therefore, we aimed to determine the distribution of the alleles related with athletic performance on successful athletes. In our cohort, CC genotype was more frequently found, and C allele was also higher in players. We think that the effect of ADR2A2 gene on athletic performance might be determined more clearly by the fact that this study is an example of similar studies involving higher numbers of subjects.
