Julien Périard Tennis in the heat

Julien Périard is a Canadian research scientist. After racing on the International Triathlon Union Circuit, he completed a PhD at the University of Sydney, investigating the mechanisms that limit prolonged exercise in the heat. He continues to be intrigued by the mechanisms that mediate performance and fatigue in adverse conditions and is now based in Qatar, an ideal place conduct heat studies in athletes. In this podcast he talks about a study he led with tennis players competing in both hot (37ºC) and cool (22ºC) conditions. He discusses the thermal, physiological and perceptual strain associated with match-play tennis in these conditions, as well as fatigue from a physical and neuromuscular performance perspective. He further discusses the impact of playing in the heat on oxidative stress, and the role of an individualized hydration regimen on performance under heat stress. He gives several important take home messages for coaches and players who plan to compete in the heat.
