Shane Heffernan

Dr. Shane Heffernan is a Senior Lecturer in Sports and Exercise Sciences at Swansea University's School of Engineering and Applied Sciences. He also serves as an associate visiting lecturer at the School of Public Health, Physiotherapy and Sports Science at University College Dublin (UCD), where he teaches the Molecular Exercise Science module on Genomics of Exercise and Sport within the Health and Performance Science degree program.

Dr. Heffernan completed his undergraduate degree in Exercise and Sport Science, followed by an MSc in Exercise Physiology and a PhD in Molecular Genetics from Manchester Metropolitan University (MMU). He also holds a PGCtHE from Swansea University. His doctoral research explored molecular genetic variation of human phenotypes from performance physiology to soft tissue and brain injury, using elite athletes as experimental models. He subsequently held a Post-Doctoral research fellowship at University College Dublin (UCD) from 2017-2019, where he researched nutrition and nutraceutical interventions for inflammation and symptomatic change in Osteoarthritis of the knee joint.

Dr. Heffernan's research spans several interconnected areas focused on the intersection of exercise science, molecular biology, and nutrition. His primary interests include: nutrition and nutraceuticals for Osteoarthritis and knee pain; mineral nutrition in health and athletic performance; plant-based nutrition for health and muscle phenotypes; and the physiology of male and female elite athletes. His work often examines how genetic factors interact with environmental and nutritional variables to influence athletic performance and injury risk. A significant portion of his research has focused on rugby athletes, investigating genetic variants associated with soft tissue injuries, concussion risk, and performance characteristics.

His recent publications demonstrate a strong focus on translational research with practical applications. He has published extensively on the genetic factors influencing sports injuries and performance, the role of nutrition and nutraceuticals in managing osteoarthritis, and the physiological responses to various dietary interventions. His work increasingly addresses contemporary issues in sports science, including athlete eligibility policies related to sex development differences and transgender inclusion in elite sport.

• Genome Conformation as a Biomarker of Concussion (2019-2021)
• The Influence of Dietary Patterns on in Vivo Skeletal Muscle and Vascular Characteristics (2020-2024)
• Dietary Assessment of Knee Pain Sufferers and Non-Pharmaceutical Oral Therapies to Improve Symptoms and Function in Knee Joint Osteoarthritis (2021-2025)

He is actively involved in supervising postgraduate research, currently overseeing PhD and MSc projects examining topics such as longitudinal biomechanical changes following knee surgery, the effects of time-restricted eating on heat tolerance, and nutritional composition in weight cutting for combat sports. His work is conducted as part of the Applied Sports Science Technology and Medicine (A-STEM) Research Centre at Swansea University.
