Ollie Jay
Ollie Jay is an Australian-Welsh academic based at the University of Sydney who is a researcher into exercise and working in hot conditions.
Career
Jay was the co-lead of a Lancet special series on exercise in the Heat, along with Kristie Ebi, which also provides annual updates, in conjunction with the Medical Journal of Australia. He also has led guidelines into safe exercise in pregnancy in the heat.
Funding for Jay's research has come from the NHMRC and Wellcome Trust amongst other sources. He has consulted for Google adding health tips when the user is in conditions of extreme heat, along with App development for heat warnings.
Jay has consulted with multiple national and international sporting organizations to assist with their policies and procedures on heat stress in athletes. He is a consultant to the Korey Stringer Institute and member of the Management Committee of the Global Heat Health Information Network.
Major tennis tournaments, played in summer, have a long history of players struggling to perform when conditions become extreme. This is thought to be getting worse due to global warming. The Australian Open, through Professor Jay's unit at the University of Sydney, has developed a metric to measure heat stress which now guides the closing of the roof, suspension of play and additional breaks in play.
Other sporting bodies
Jay has also consulted with other sports, including Cricket Australia, the National Rugby League, the Australian Institute of Sport and Sports Medicine Australia to develop their heat policies, which similarly provide objective data by which to measure heat stress on players and justify decisions for suspension of play or additional drinks breaks. He is being retained by the Australian Olympic team as an expert heat consultant for the 2024 Paris Olympics. He was also an author on the IOC position statement on Exercise in the Heat.
