What is the elite athlete gene?

Studies have found that most elite power athletes have a specific genetic variant in a gene related to muscle composition called the ACTN3

ACTN3

Alpha-actinin-3, also known as alpha-actinin skeletal muscle isoform 3 or F-actin cross-linking protein, is a protein that in humans is encoded by the ACTN3 gene (named sprinter gene, speed gene or athlete gene) located on chromosome 11. All people have two copies (alleles) of this gene.

gene. This variant causes muscle cells to produce alpha-actinin-3, a protein found in fast-twitch muscle fibers.

How common is the elite athlete gene?

That study also found about a 40 percent prevalence of the CC genotype among elite power athletes. The AGT gene is part of the renin-angiotensin system, which plays essential roles in regulating blood pressure, body salt, and fluid balance.

What is the super athlete gene?

EPAS1 is activated when oxygen levels in the blood drop, triggering production of more hemoglobin. This gene has been referred to as the super-athlete gene because at low elevations, some variants of it help athletes quickly boost hemoglobin and thus the oxygen-carrying capacity of their blood, upping endurance.

How common is the ACTN3 gene?

This variant form of the ACTN3 gene is very common in the general population. Approximately 20%-30% of the population (over 1 billion people worldwide) have two mutant genes (X/X genotype), and there is not any obvious effect on individuals who have either one or two copies of the variant gene.

Does Usain Bolt have ACTN3?

It is almost certainly true that Usain Bolt carries at least one of the "sprint" variants of the ACTN3 gene, but then so do I (along with around five billion other humans worldwide).

Are elite athletes born or made?

How do I know if I have the ACTN3 gene?

Here's how to check your ACTN3 gene:

Check your genetic data for rs1815739 (23andMe v4, v5; AncestryDNA): C/C: functioning ACTN3, optimal for elite power athletes, more type IIx muscle fiber (RR) C/T: functioning ACTN3, optimal for elite power athletes (RX)

Does everybody have the ACTN3 gene?

The ACTN3 gene is only carried by a small portion of the population – in Europe, only 18%. The gene regulates the ACTN3 protein, which is produced in fast-twitch muscle fibers.

Is the sprinter gene real?

What is the ACTN3 Gene? The ACTN3 gene is specifically found in fast-twitch (type II) muscle fibers, which are in charge of producing forceful muscle contraction that are especially needed for sprinting and weight-lifting. The gene produces a protein that regulates the function of these fibers.

How do you tell if you have athletic genes?

What gene makes you fast?

The ACTN3 gene provides instructions for making a protein called alpha (α)-actinin-3, which is predominantly found in fast-twitch muscle fibers. A variant in this gene, called R577X, leads to production of an abnormally short α-actinin-3 protein that is quickly broken down.

Is there a gene for power?

There is a clear, undoubted impact of genetics on both sporting performance and exercise adaptation. In this regard, one of the most well-studied genes is ACTN3, which has been reliably shown to impact speed-power and strength phenotypes.

Is fast twitch muscle genetic?

The genetic link

Studies have found that most elite power athletes have a specific genetic variant in a gene related to muscle composition called the ACTN3 gene. This variant causes muscle cells to produce alpha-actinin-3, a protein found in fast-twitch muscle fibers.

Where does the athletic gene come from?

Two of the genes most studied in relation to athletic performance are ACTN3 and ACE, which “influence the fiber type that makes up muscles, and they have been linked to strength and endurance.” In addition there are other genes which have been associated with athletic performance, such as those which play a role in ...

What's the sprinter gene?

We all have a gene called ACTN3, but certain variants of it help our bodies make a special protein called alpha-actinin-3. This protein controls fast-twitch muscle fibers, the cells responsible for the speedy tensing and flexing of the muscles involved in sprinting or weight-lifting.

What ethnicity has the sprinter gene?

Scientists conclude that it is almost impossible for someone who lacks the ACTN3 protein to become an elite sprinter. Those of African ancestry have the lowest incidence of the mutation that prevents the muscles from firing.

How many people carry the sprinter gene?

One out of six people carry a variant of the FTO gene. This gene was originally dubbed the 'fatso' gene since it was so large, and it was soon discovered that it was linked to obesity. The bad news is that people who carry this genetic variant are at a much higher risk of obesity.

Is Usain Bolt's speed genetic?

But even among top sprinters, Bolt stands out, and this is partly because of his height. "Bolt is a genetic freak because being 6ft 5ins tall means he shouldn't be able to accelerate at the speed he does given the length of his legs," says former Great Britain sprinter Craig Pickering.

Where does ACTN3 gene come from?

Alpha-actinin-3, also known as alpha-actinin skeletal muscle isoform 3 or F-actin cross-linking protein, is a protein that in humans is encoded by the ACTN3 gene (named sprinter gene, speed gene or athlete gene) located on chromosome 11. All people have two copies (alleles) of this gene.

How is the ACTN3 gene inherited?

Because every human inherits two copies of the ACTN3 gene-one maternal and one paternal copy-there are three possible combinations or genotypes of R577X alleles.

Is being a fast runner genetic?

Researchers say our genetics are designed to make us run at energy-efficient speeds to preserve calories. They say that may explain why some runners have trouble improving their race times. Experts say there are ways to train your body to overcome this hereditary limitation.

Do Asians have fast twitch muscle fibers?

East Asians (and Southeast Asians) have stronger extremities and longer torso, plus greater amount of fat in certain areas, smaller bodies, higher amount of slow twitch muscles.

Why is bolt so fast?

HIs longer leg length leads to longer step length and therefore greater speed (Debaere, 2013). With Usain Bolt towering at 1.96m and weighing 96 kg , he has a stride advantage over his smaller competitors. Joint Angles are another biomechanical variable to consider.

What type of mutation is ACTN3?

The alpha actinin 3 (ACTN3) gene is 16,489 base pairs and consists of 22 exons and 21 introns. ACTN3 has a single nucleotide polymorphism (SNP) that confers a nonsense mutation (C >T transition at nucleotide 1747, R557X) in exon 16 (see star) resulting in a truncated protein.
