The relation between self-paced exercise performance and EEG activity: Influence of hot and hypoxic conditions

The relation between self-paced exercise performance and EEG activity: Influence of hot and hypoxic conditions

In collaboration with associate Professor Julien Périard, PhD

Heat stress and acute hypoxic exposure are known to negatively influence endurance performance during exercise (Bergeson, 2014; Nielsen, Hales, Strange, Christensen, Warberg & Saltin, 1993; Santos-Concejero, Tucker, Myburgh, Essen-Gustavsson & Kohn, 2014). One of the potential pathways mediating the decrease in performance is a change in cerebrocortical activity resulting from the impact of such extreme environments.

Research suggests that hyperthermia may lessen arousal (Nielsen, Hyldig, Bidstrup, González-Alonso & Christofferson, 2001) while hypoxia may alter neuronal transmissions (Peña & Ramirez, 2005). It is yet to be determined how hyperthermia and hypoxia influence the cerebrocortical activity during self-paced exercise. Our team therefore aim to explore the exact nature of the cerebrocortical response under normal (cool), hot, and hypoxic environments during self-paced exercise.
