Hydration and performance in the heat: guidelines history, controversies and current recommendations

Professor Julien Périard is deputy director of the University of Canberra Research Institute for Sport and Exercise (UCRISE), where he also leads the environmental physiology research laboratory. His integrative research examines the physiological mechanisms that mediate health and performance during exercise in adverse environments (heat and altitude) and the adaptations that stem from chronic exposure to these environments. His work also involves the development of extreme heat policies for sport and exercise and examines how regular exercise across the lifespan can build resilience against rising global temperatures. He has worked with both amateur and professional athletes from various disciplines, along with National (e.g. Australian Institute of Sport) and International Federations (e.g. FIFA, World Athletics and World Triathlon). Julien has authored over 120 research publications, including an invited review for Physiological Reviews. He has also edited a textbook on Heat Stress in Sport and Exercise. He currently serves as associate editor for the Journal of Science and Medicine in Sport and has served as guest editor for the British Journal of Sports Medicine and Scandinavian Journal of Science and Medicine in Sport.
