The Summer Olympics may be over but we’re all still reeling from the incredible performances and accomplishments by the best athletes in the world. As we sat with our eyes glued to the screens, we asked ourselves, “how are these humans capable of such speed, strength, and endurance?” It truly is mind boggling, but sports psychologists may have an explanation as to what sets these athletes apart from the rest of us.
After decades of studies focused on genetics, physical attributes, aerobic capacity, and muscular functions, researchers have narrowed their focus to a brain chemical: dopamine. Dopamine is a neurotransmitter that controls the reward and pleasure center of our brains. It also helps us handle stress and perceive pain. This research suggests that what sets elite athletes apart from the rest of us isn’t physical at all – it’s mental!
Scientists collected DNA samples from 50 Olympic athletes and 100 recreational athletes. When comparing genes across these two groups, they found a significant genetic difference in regards to dopamine transport. The dopamine active transporter (DAT) was five times more prevalent among elite athletes than in the recreational athlete group. Based on earlier animal studies, this means that elite athletes are prone to increased motor activity, energy expenditure, and reward-seeking behavior. In other words, elite athletes want more and aren’t afraid of taking risks to reach their goals. The downside to this is that dopamine transporter has also been linked to depression, ADHD, bipolar disorder, and Parkinson’s disease, which we’ve seen in some Olympic athletes.
What does this mean for the rest of us? It means that we can take this information and find ways to naturally increase dopamine activities in our brains. We may not end up on the Olympic podium, but it’ll certainly help us achieve our individual fitness and wellness goals. Here are the best ways to naturally boost dopamine levels:
We may not be Olympic athletes but, like them, we have fitness goals that we want to achieve. By watching what we eat, getting the right amount of rest, and exercising regularly, we not only naturally boost the dopamine levels to help us achieve our goals, we also set ourselves up for better health and wellness.
Jenn Giles, R.D., C.S.S.D. is all about health and wellness. She has over 15 years’ experience, including a dual master’s degree in Nutrition and Exercise Physiology from Columbia University. She is a Registered Dietitian (RD) and a Board Certified Specialist in Sports Dietetics (CSSD). She supplements all of this with her spin instructor certification and USATriathlon Level I Coach Certification.
Jennifer is passionate about (actually, obsessed with) the sport of triathlon. She has been personally participating in triathlons since 2000 and running road races since 1992. She is a two-time Ironman finisher and has completed countless numerous marathons. She has been a member of Power Bar Team Elite since 2006 and competed as a member of the 2006 Aquaphor/Active.com Sponsored Athlete Team. She was ranked as USAT All American Honorable mention in 2006 and 2011. Jennifer does all of this along side of her husband, Patrick, who is an equally accomplished triathlete and runner. They try as hard as they can to do all of their training and racing together.
She will tell you, however, that her most important, most rewarding and most challenging job is as a mother of four. She knows first hand the challenges of maintaining optimal fitness, overall good health and achieving goals while raising a family - of which good nutrition is the cornerstone.
Most importantly, she knows how to motivate, inspire and challenge athletes based on their own abilities, strengths and everyday lifestyles. She believes there is an athlete in everyone - no matter what their abilities are – and if those abilities are manifold, then there is an even better athlete in there!
