The Effect of PPARα Gene Polymorphism on Some Athletic Performances of Non-Athletic 10-12 Year-Old Boys of Marand

  one of the key concepts in physical education and sport science is the process of talent identification. The purpose of this research was to investigate the effect of PPARα gene polymorphism on some of the athletic performances of non-athlete 10-12-year-old children. The present project was carried out in the form of semi-experimental and field-based research with salivary sampling. To determine the polymorphism of the genes, the methods used included saliva sampling, salvary DNA extraction and PCR-RFLP method and exercise tests included the Shuttle run, standing broad jump and 20m sprint. Our subjects consisted of 118 non-athletic healthy boys of Marand from 10 to 12 years old. After comparison with Hardy-Weinberg equilibrium, frequency of genotype was tested with Leven, Fisher and Kolmogorov-Smirnov tests. Using one-way covariance analysis, the mean group phenotypes was compared with each other. Type of polymorphism as a predestine variable and the athletic performances of 20m shuttle run, standing broad jump and 20m sprint test were considered as the criterion variable. All analyzes were performed by SPSS 22.
Findings: The results showed that the subjects with PPARα gene GG polymorphism had better performance in the endurance tests than subjects with CC and GC polymorphism. It can be concluded that GG polymorphism is related to the endurance activities, but CC and GC polymorphisms do not have a particular predominance in the endurance, speed and power activities
