Abstract
Background: Today, by determining the genotype, genetic science can check in which sport a person can perform more successfully.In this study, two important polymorphisms; one is ACTN3, which plays an essential role in the formation of the diversity of muscle fibers, and the other is VDR, which plays a vital role in the growth of muscle fibers and bones, were investigated.
Methods: In this study, 200 male and female professional athletes, with normal BMI and at least five years of previous professional sports, in the age range of 20-35 years with a peak power score of 1000-1100 W in the male population; and Peak power: 700-750 W in the female population by examining the Wingate test, and the minimum muscle percentage of SMM: 30% were selected according to the body composition machine analyzes and compared with the control group of 200 people. After sampling and DNA extraction, polymorphisms were analyzed using the RFLP-PCR technique analysis software.
Findings: The results of the present study showed that there is a significant difference between the muscle mass indices and the Wingate test score between the male and female populations in the ratio of control samples, also significant differences were observed for the rs1815739 polymorphism in the heterozygous state and the rs2228570 polymorphism in the homozygous form.
Conclusion: It seems that in the polymorphism of rs1815739, athletes need both types of fast and slow twitch muscle fibers for their success, and moreover the existence of more homozygous GG in the polymorphism of rs2228570 has helped athletes absorb vitamin D better.
