Background and Purpose: In the last decade, ACTN3 gene has been introduced as a suitable representative for muscle strength and power that can be effective in guiding adolescents to related sports. The aim of this study was to investigate the relationship between ACTN3 gene polymorphism and strength and power indices of adolescent weightlifters in Ardabil. Methodology: The subjects of the study were 16 adolescent weightlifters from Ardabil. Measured athletic performance included explosive strength and power. ACTN3 gene polymorphism was examined by Tetra-ARMs PCR. Results: The results showed a significant difference in the genotypic frequency of ACTN3 gene polymorphism in the subjects, which had the highest frequency in the genotypes RX=63%, RR=31% and XX=6%, respectively. The results showed no significant difference in strength and power performance index between all three genotypes. Conclusion: The results showed the superiority of genotype RX=63% in ACTN3 gene of Ardabil weightlifters, Due to the superiority of the RX genotype and the RR genotype in strength and power tests, respectively, in the region, people with the ACTN3 gene R allele are probably more successful in strength and power sports, which of course requires more research in this area.
