Résumé : International audience
Facts -The capacity to exercise is markedly reduced in hot environments. -High humidity imposes further physiological strain on the body. -The combination of exercise and hot environments increases the risk of heat illness and heatstroke. Recommendations for players -Fluid intake should be sufficient to restrict body mass loss to o2% of the pre-exercise mass. -A minimum of 1-2 weeks of acclimatization should be undertaken before playing in a hot environment. Recommendations for organizers -Perform pre-participation screenings before competing in the heat. -Watch at-risk individual (e.g. sickle cell trait, vascular disease) and observe signs and symptoms if WBGT > 28°C. -Add additional fluid breaks and foresee medical coverage if WBGT > 30°C. -Reconsider event if WBGT > 32°C. Future research should investigate -The optimal cooling strategies prior and during sporting activities, i.e., halftime in football games. -The influence of acclimatization on football performance. -The impact of heat on decision making in players and match officials. -The impact of heat on spectators from cooler regions.
