Frequency and Association of SNP rs 8111989 in CKMM A/G Gene in Weightlifting Men with Non-Athlete Men

Genetic factors affect physical performance, exercise response, as well as elite athletic status; Therefore, the aim of the present study was the investigation of the Frequency and association of SNP rs 8111989 in CKMM A/G gene in weightlifting men with non-athlete men.

In this descriptive study, the subjects were include of all (n=30) elite male weightlifters (league champions, members of national team, and the champions of Asian, world and Olympics) from Isfahan province, age: 21.77±7.11; Height: 179.87±6.98 and weight: 96.87±22.73 (mean±standard deviation) Which compared with 44 non-athletes with similar anthropometric (age, height and weight) characteristics. 4 cc saliva samples were collected from each subject and After DNA extraction, the allelic and genotypic prevalence of CKMM A/G gene was determined by PCR via RFLP and electrophoresis. Independent t-test, chi-square and logistic regression were used to analyze the data via the SPSS software version 20. Also the significance level was considered at P<0.05.

The results showed that the prevalence of AG genotype was significantly higher than AA and GG genotypes in weightlifting, non-athlete and total population groups (P <0.05). Also, there was no significant relationship between CKMM A/G genotype and weightlifting status and there was no significant difference between weightlifters and non-athletes (P >0.05).

The results showed that the selected Iranian weightlifter, which belongs to the Caucasian race group, has potential genetics in endurance abilities as well as strength / power, likely.
