Variations in One Gene May be Associated with Endurance Running

17.02.2010
A few minor variations in one gene may make a difference in athletic endurance, according to a new study from Physiological Genomics.

The study found that elite endurance athletes were more likely to have variations of the NRF2 gene than elite sprinters. Non-elite endurance athletes were also more likely to have the genetic variations compared to sprinters, although the difference was not as pronounced.

The study shows an association between the gene variation and endurance, but does not establish a cause-effect relationship. Future studies are needed to unravel exactly what role the gene plays in athletic performance. The study is part of a larger body of research that is exploring the human genome and which aims to understand the genetic underpinnings of athletic performance.

Although the human genome is relatively uniform, there are variations among individuals. The researchers investigated the NRF2 gene because previous studies have shown that it may play a role in endurance performance because it:

· helps produce new mitochondria, a key cellular structure that produces energy
· reduces the harmful effects of oxidation and inflammation, which increase during exercise

“These findings suggest that harboring this specific genotype might increase the probability of being an endurance athlete,” said one of the authors, Nir Eynon of Wingate Institute in Israel. The study, “Interaction between SNPs in the NRF2 gene and elite endurance performance,” was carried out by Dr. Eynon, Alberto Jorge Alves, Moran Sagiv, Chen Yamin, Prof. Michael Sagiv and Dr. Yoav Meckel. All are at the Wingate Institute except for Alberto Alves, who is with the University of Porto in Portugal. The American Physiological Society (www.the-APS.org) published the study.

The Study
The study examined 155 track and field athletes who had competed in national or international track and field competitions. The athletes were further subdivided into endurance group (10,000 meter and marathon runners) and a sprint group (100- and 200-meter and long jump). The control group consisted of 240 non-athletic healthy individuals.

These groups were further divided into elite-level (those who had represented Israel in the world track and field championships or in the Olympics) and national-level (those who had competed in national competitions, but not international).

The study found that two variations in the NRF2 gene (specifically, the NRF2 A allele and the NRF2 C/T genotype) occurred more often in endurance athletes than in sprinters. “Eighty percent of the elite-level endurance athletes were carrying the A allele of the NRF2 A/C single nucleotide protein, compared to only 46% of the elite-level sprinters,” Nir. Eynon said. The study also found that the combined NRF2 AA+ NRF2 C/T genotype was more frequent in endurance athletes than in the sprinters group and the control group.

“So,” concludes Eynon, “some of us are truly born to run.”

Physiology is the study of how molecules, cells, tissues and organs function to create health or disease. The American Physiological Society (APS) has been an integral part of this scientific discovery process since it was established in 1887.

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....

Im Focus: Researchers Develop Data Bus for Quantum Computer

The quantum world is fragile; error correction codes are needed to protect the information stored in a quantum object from the deteriorating effects of noise. Quantum physicists in Innsbruck have developed a protocol to pass quantum information between differently encoded building blocks of a future quantum computer, such as processors and memories. Scientists may use this protocol in the future to build a data bus for quantum computers. The researchers have published their work in the journal Nature Communications.

Future quantum computers will be able to solve problems where conventional computers fail today. We are still far away from any large-scale implementation,...
