Behavioural Adabtations during Exercise in Extreme Ambient Temperatures

This invited lecture will discuss how thermal homeostasis is defended via behavioural responses and the resulting effects on performance. It is well known that the human capacity to perform prolonged exercise is profoundly impaired in hot or cold environments. What is less known is that the thermoregulatory system relies primarily on behavioural adaptation and secondarily on autonomic and endocrine responses for the maintenance of thermal homeostasis. Despite the challenges involved in effectively isolating human behavioural responses, a number of studies have demonstrated that behavioural thermoregulation is a major determinant of performance. Changes in ambient temperature affect our heat balance and lead to behavioural responses that are translated to changes in the work produced. In this light, evidence shows that behaviour is primarily driven by thermal (dis)comfort, while autonomic thermoregulation is mainly stimulated by thermal sensation. Suggestions for training and event days will be provided aimed towards maximising the athlete’s wellbeing and performance.
