Dr. Shawn Arent, a leading professor at the University of South Carolina, shares his extensive research on how nutrition impacts athletic performance and cognitive function. The conversation dives into the roles of carbohydrates in cognitive decision-making and the effects of protein and caffeine on fatigue and focus. Arent highlights intriguing supplements like creatine and omega-3s for brain recovery post-injury. They also discuss the emerging use of theacrine and tyrosine in enhancing mental performance, raising essential questions about their scientific backing and practical application.

Cognitive Performance in Athletes
Cognitive performance is crucial for athletes in decision-making during fatigue.
It also includes vigilance, rapid response, and concentration under pressure.
insights INSIGHT
Carbohydrate's Impact on Cognitive Function
Carbohydrates are crucial for cognitive function, especially in endurance sports where glycogen depletion is high.
Maintaining stable blood glucose levels delays fatigue and enhances decision-making.

Fueling vs. Mouth Rinsing
Prioritize proper fueling over carbohydrate mouth rinsing for athletes.
Consistent carbohydrate intake is more beneficial long-term.

In the world of sports nutrition, understanding how different supplements and nutrients impact not just physical performance but also cognitive function is rapidly gaining traction. Athletes are constantly seeking that competitive edge, and while many are familiar with the benefits of carbohydrates and caffeine for energy and focus, there’s much more at play.
Emerging research is highlighting the roles of compounds like creatine and omega-3s, not only for muscle recovery but also for brain health, particularly following traumatic brain injuries (TBI).
Beyond the usual suspects of performance nutrition, intriguing compounds like theacrine and tyrosine are entering the conversation. With potential cognitive effects that range from improved focus to faster decision-making, these supplements have sparked interest but also raise questions.
How strong is the evidence behind these claims, and where do we draw the line between scientific promise and practical application? How do we apply the science in real-world settings where perfect data may not exist?
This episode addresses these questions via the insights of Professor Shawn Arent of University of South Carolina.
