Here is a bit of information about each one:ĪCTN3: The alpha actin protein (ACTN3), or what some people are calling "The Speed Gene" is a component of the contractile apparatus in fast skeletal muscle fibers and is important for generating force at high velocity. They are the following:ĪCE I/D, ACTN3 R577X, IL6 -174 G/C, and NOS3 -786T>C The following 4 gene variants have been the most researched when it comes to to influencing power performance. The thought is that an individuals genes can eventually be tested beforehand to identify potentially elite talent.
They affect a variety of functions including blood flow to muscles, muscle structure, oxygen transport, lactate turnover, and energy production.
Genetic variants associated with over 200 genes are documented to effect athletic performance. Well, scientists have identified a myriad of potential performance enhancing genes, and gene combinations work together to produce an enhanced or synergistic effect on performance. When someone is born with great athletic ability many are quick to say, "It's all in the genes" It is true that qualities like speed and jumping ability can be highly influenced by genetic factors, but is there a single gene or combination of genes that identifies potential in events such as speed and vertical jump?
