Abstract : This article reviews the effects of hot environments--and thus hyperthermia and hypohydration--on circulation, strength, endurance, and health in athletes. The cardiovascular responses to heat exposure at rest, and during exercise, are reviewed. Performance is reviewed by examining strength, power and endurance; the impact of hyperthermia, hypohydration and diuretic use on performance are discussed. The physiological needs for water, salt and carbohydrates have been examined. The four major heat illnesses (i.e. heat cramps, heat syncope, heat exhaustion, heatstroke) are described, as well as preventive measures to counteract hyperthermia and hypohydration. Keywords: Cardiac output, Strength(Physiology), Endurance(Physiology), Heat illness, Water, Electrolytes.
