Dr. José L. Areta is a lecturer in Sports Nutrition at Liverpool John Moores University currently specializing on the endocrine, metabolic and physiological effects of low energy availability (LEA) and how these may affect performance. Originally trained as a biologist —with a minor in zoology—, José specialised in sports nutrition during his PhD studies at RMIT University in Australia and part of José’s PhD focused on the effect of LEA on skeletal muscle protein synthesis. Following this research experience and in line with his interest in skeletal muscle glycogen and adaptation to training and performance, José undertook post-doctoral research training after his PhD at the Norwegian School of Sport Science. During this post-doc, he researched the dynamics of skeletal muscle glycogen use during exercise and the interaction between muscle glycogen and acute changes in energy availability on training adaptation. In parallel with his research/academic career, José works as an applied practitioner and consultant in sports nutrition for elite athletes, particularly endurance athletes, in the Americas, Oceania, and Europe and strives to apply the latest scientific research and rigorous observation to achieve best performance.
