ABSTRACT
Metabolic heat production in squash must therefore be high. As the sport is popular throughout the world and played in all seasons, it is reasonable to assume that court conditions in the warmer seasons impose considerable environmental heat stress on players, additional to the metabolic heat produced, compounding their physiological strain. Seasonal changes in court conditions and physiological demands therefore warrant investigation. The aims of this study were to describe the seasonal variations in environmental heat stress imposed on players in a non-airconditioned Sydney complex, to investigate the influence of these variations on physiological strain, and to determine the implications of this for match preparation and performance.
