Introduction
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.

Dr. Arent’s research focuses on the relationship between physical activity and stress and the implications for health and performance. The primary emphasis of his research in this area involves examining underlying endocrine mechanisms and biomarkers related to the HPA axis and inflammation.
He is specifically interested in the potential efficacy of acute and chronic resistance training as well as nutritional interventions for improving functional capabilities, mental health states, and the systemic response to stress in athletes, military and first-responders, adolescents, and special populations.
Dr. Arent’s recent work has primarily focused on physiological responses to training-related stressors and their contribution to optimal performance and recovery.
Danny Lennon has a master’s degree (MSc.) in Nutritional Sciences from University College Cork, and he is the founder of Sigma Nutrition.

Useful Terminology for this Episode
| Key Terms & Acronyms |
| Cognitive Performance: The ability to effectively use mental processes such as attention, memory, problem-solving, and decision-making, especially under demanding conditions. In sports, cognitive performance impacts how well an athlete can make quick decisions, maintain focus, and respond accurately during high-stress or fatigue.
Glycogen: A stored form of glucose found primarily in the liver and muscles, serving as a key energy source during physical activity. Glycogen is essential for maintaining energy levels, especially in prolonged or high-intensity exercise, as depletion can impair both physical and cognitive performance. Branched-Chain Amino Acids (BCAAs): A group of three essential amino acids—leucine, isoleucine, and valine—that are important for muscle protein synthesis and may also support cognitive function by influencing serotonin synthesis and delaying mental fatigue. Essential Amino Acids (EAAs): Amino acids that the body cannot produce on its own and must obtain through diet. EAAs are critical for protein synthesis and neurotransmitter production, supporting both physical and cognitive functions. BCAAs are a subgroup within EAAs. Traumatic Brain Injury (TBI): An injury to the brain caused by an external force, such as a blow to the head, which can lead to temporary or permanent cognitive, physical, and emotional impairments. TBI o en disrupts brain function. |
