Wetsuit use is permitted in Olympic-distance triathlons below a water temperature of 22°C, or 20°C for elite athletes, and mandatory in water below 14°C [1]. They improve insulation against heat loss during swimming, increase buoyancy and reduce the afterdrop (continuing fall in deep body temperature after leaving the water) during subsequent cycling [2]. The aim of this study was to compare performance and body temperature of high-level triathletes swimming in water at 14°C with and without wetsuits, before cycling at race pace for an Olympic-distance event, as the Olympic event is the focus of the International Triathlon Union and International Olympic Committee.
