We thank the correspondents  for their interest in the recent consensus statement on training and competing in the heat . However, we were somewhat perplexed to note that the authors considered that the consensus statement “did not highlight one of the main current limitations: the recommendations for various sporting governing bodies (i.e., event organizers and international federations) are still based on the Wet-Bulb Globe Temperature (WBGT) index”.
Indeed, one of the main recommendations in the consensus statement is that “the WBGT is an environmental heat stress index and not a representation of human heat strain. It is therefore difficult to establish absolute participation cut-off values across sports for different athletes and we rather recommend implementing preventive countermeasures or evaluating the specific demands of the sport when preparing extreme heat policies” .
