Military personnel are called upon to serve in hot, dry or humid climates, which places great demands on their ability to tolerate heat. Induced heat stress can impair performance and lead to pathologies. Faced with the challenges of global warming, this issue is becoming increasingly important in the practice of sport. While hyperthermia is known to impair endurance performance, the underlying thermophysiological responses and regulatory mechanisms during prolonged exercise remain poorly understood. The effects of hyperthermia on mental performance raise questions about the degradation of interoceptive capacities and the deleterious impact on behavioral regulation, an important component of thermal risk management in ultra-endurance exercise. What's more, despite the muscular and hydromineral consequences (rhabdomyolysis, renal failure, dehydration) of prolonged exercise, few data are available on recovery kinetics. A better understanding of the factors conditioning recovery quality could help limit the deleterious consequences of ultra-endurance exercise.
