After the scientific studies, some genes related to muscle structure and cardiovascular capacity have been determined.

Today; In order to determine the cardinal capacity of ACTN3 gene region for the determination of muscle structure, gene changes in the ACE gene region are evaluated.

Changes in the 577 point of the ACTN3 gene (R577X) affect the performance of the muscle by altering the nature of the muscle structure. The alpha-actin-3 is produced less in those in which the R577X exchange is observed, and the individual's sporting performance and the sporting areas in which it is prone may vary.

Furthermore, the positive effect of ACE gene region on athletic performance has been proven. Since the changes in the ACE gene region are effective on cardiac capacity, it affects the sports performance of the person and the sports branches it is prone to.
