This review looks at a wide range of past research to understand how much our genes influence athletic performance. The authors pulled together findings from multiple genetic studies and large resources like the UK Biobank. By mid-2023, they had identified 251 DNA variants connected to athletic ability in some way. Out of those, 128 showed consistent results across more than one study, so those became the main focus when looking at endurance, power, and strength traits.
The paper also breaks down how certain genetic patterns tend to appear more often in different types of athletes. Some variants are more common in endurance athletes, others show up in sprinters or power athletes, and some appear more in strength-oriented athletes. The overall takeaway is that there isn’t one single “athlete gene.” Instead, different combinations of genes may contribute to different types of athletic strengths.
The authors also emphasize that genetics is only part of the story. Training, nutrition, mindset, environment, and lifestyle all play major roles as well. Even though genetics account for a noticeable portion of athletic variation (around 66%), having favorable genetic markers doesn’t guarantee elite-level performance. The study suggests viewing genetics as one informative piece of a much broader picture, rather than a definitive predictor.

This is an incredibly interesting idea because it shows that our genes can shape our athletic ability, but they’re not the guarantee to excellence in sports. Training, mindset, nutrition, and environment matter just as much. Even though our genes play a significant role (such as height for a basketball player), they’re just one piece of the bigger puzzle to athletic ability.
ReplyDeleteThis is really interesting. I believe that great athletes have the genetic predisposition to be dominant, but it’s their drive and dedication to their craft that ultimately lets them succeed. If you have noticed, many of the best long distance runners are Kenyan and Ethiopian, they have the genetic predisposition to be better than some others, but it is their drive that ultimately makes them great.
