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… (Source: Health News from Medical News Today)
