Abstract
This paper briefly reviews certain aspects of man's response on exposure to a hot climate. The value of applying the concepts of thermal exchange analysis to evaluate the severity of a particular heat stress situation is emphasised. The possible effects of the Rome climate on a marathon runner competing in the 1900 Olympic Games is used as an illustration. It is concluded that with more knowledge of the physiology of athletes the accuracy of such predictions could be much increased, and might then be helpful to the athlete in planning the strategy of his race.
