Investigation of anthropometric properties with rs1805086 and rs1805065 polymorphisms of mstn gene in professional, amateur arm wrestling athletes and sedentaries

This study aims to analyse MSTN rs1805086 and rs1805065 polymorphisms and anthropometric properties such as palm width, wrist width and forearm width in national and amateur arm wrestlers and sedentary group. 24 national (7 female, 17 male) and 21 (7 female, 14 male) amateur Turkish arm wrestlers and 34 sedentary group (12 female, 22 male) voluntarily participated in this study. Genetic infrastructures of the volunteers were determined by some molecular methods such as DNA isolation, Polymerase chain reaction (PZR) and Restriction fragment length polymorphism (RFLP), respectively. In addition, anthropometric characteristics (palm width, wrist width and forearm width) were measured with gullick tape measure. When the MSTN rs1805086 and rs1805065 data are respectively examined at the end of the study; 100.0% MSTN 153KK genotype was found in both national arm wrestlers (n = 24) and amateur arm wrestlers (n = 21) while 94.12% MSTN 153KK genotype, and (n = 2) 5.88% MSTN 153KR genotype were found in sedentary group (n = 32). All participants who participated in the study (n = 79, 100.0%) were found to be homozygous normal genotype (i.e. 55AA) carriers according to the results of the other MSTN rs1805065 polymorphism data examined in this study. In addition, statistically significant differences were found in terms of anthropometric properties both in men's and in women's category (p <0.05). In conclusion, although there is no significant difference in properties of MSTN gene among national and amateur arm-wrestler and sedentary group, some differences in anthropometric properties are found out. It was concluded that the MSTN gene was not effective in the success of these athletes but it plays a role anthropometric properties or other genes which affect sportive performance.
