A study from the University of Essex in England explains how genetics may play a role in determining how fast and how well someone can run. According to the study, fewer than 31 percent of people have a unique genetic combination that allows them to get the most out of their training efforts. One gene in particular, known as ACTN3, is associated with adaptability, speed, power, improved strength, and reduced risk of injury. Researchers found that all of the top performers in the study shared a variant of this gene.

The test was conducted on men and women between the ages of 20 and 40 and lasted for eight weeks. During the study, researchers used the Cooper Test, a method often used by the military to measure aerobic fitness. Participants were asked to run as far as possible in 12 minutes. After completing the training period, researchers observed that those who possessed the ACTN3 gene improved their performance by an average of 11.5 percent following the eight weeks of endurance training. Participants who lacked this specific gene showed little to no improvement, even though they followed the same training conditions as everyone else.

Now, is it all in the genes?

Dr. Chung explains that “this study supports the fact that genetics play a major part in athletic performance. Whether you are an elite competitor or training for a fun run, your DNA can make a real difference in how much you can push yourself.” However, he also emphasized that the absence of this gene is not an obstacle for aspiring runners. At the end of the day, what matters most is getting out, training, and staying active. Our genes may provide the starting line, but our effort, dedication, and consistency ultimately determine how we perform on the track. While DNA can influence how much we improve, it is still willpower and commitment to the sport that truly drive success.
