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:
“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
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.

On the way to an intelligent laboratory, physicists from Innsbruck and Vienna present an artificial agent that autonomously designs quantum experiments. In initial experiments, the system has independently (re)discovered experimental techniques that are nowadays standard in modern quantum optical laboratories. This shows how machines could play a more creative role in research in the future.

At the JEC World Composite Show in Paris in March 2018, the Fraunhofer Institute for Laser Technology ILT will be focusing on the latest trends and innovations in laser machining of composites. Among other things, researchers at the booth shared with the Aachen Center for Integrative Lightweight Production (AZL) will demonstrate how lasers can be used for joining, structuring, cutting and drilling composite materials.
No other industry has attracted as much public attention to composite materials as the automotive industry, which along with the aerospace industry is a driver...
