This review discusses how hyperthermia impacts cognitive processing and exercise performance in high temperatures.
Exercise in a hot environment can impair performance due to not only impaired coordination of major physiological systems but also reduced cognitive processing related to the exercise strategy. In this review, we discuss potential factors contributing to reduced exercise performance during excessive brain temperature elevation, with a focus on the functional localization of brain activity. Summary: A localized increase in prefrontal cortex temperature impairs performance in exercises that require cognitive processing.
