The attenuation of exercise duration/performance during exercise in the heat has spawned the use of exercise and heat stress as a model for fatigue. However, the mechanisms underlying premature fatigue in the heat remain unclear and have been debated accordingly. Principle to this debate is the use of both fixed-intensity and self-paced exercise protocols which have produced seemingly opposing theories. However, a retrospective analysis of previously published data suggests that these theories are in fact complementary and act together in order to maintain thermoregulation and prevent the development of exertional heat stroke.
