A high frequency of the ACTN3 gene, which is associated with the development of fast-twitch muscle fibers, explosive power, and sprinting abilities, has been identified in many representatives of the Kazakh ethnic group. This is highlighted in a number of studies and scientific discussions, El.kz reports.
The ACTN3 gene is responsible for the synthesis of the α-actinin-3 protein, which plays a crucial role in the function of fast-twitch muscle fibers.
Scientists suggest that the relatively high prevalence of the functional variant of this gene may be one of the factors contributing to the success of Kazakhstani athletes in sports requiring explosive strength, such as wrestling, weightlifting, and boxing.
In addition, researchers are studying gene variants in Kazakhs related to adaptation to low-oxygen conditions (hypoxia), which may be linked to their historical habitation in steppe and mountainous regions.
While such studies help to better understand the genetic characteristics and predispositions of a population, experts emphasize that athletic success is always determined by a combination of genetics, training, nutrition, and other factors.
