Hyperthermia effects on brain function and exercise capacity
Bibliographic record
Abstract
Hyperthermia has been demonstrated as an important factor limiting endurance performance in a hot environment in both human and animal studies. While temperature can affect individual peripheral physiological systems such as muscle contraction characteristics directly, a dominant role for central mechanisms for exercise impairment has been proposed over the past two decades. Exercise-induced hyperthermia may have a direct effect on the central nervous system such as brain temperature, cerebral blood flow, brain activity, cognitive function, brain neurotransmission and neuromuscular activity. In turn, these changes may affect not only the physiological capacity for exercise, but also the athlete’s perception of heat stress, motivation for exercise or pacing strategy. The purpose of this review is to focus on the central mechanisms underlying human limits to exercise in heat. Specifically, the effects of hyperthermia on brain physiology and function will be summarized, along with the potential impact of these changes on regulating exercise capacity.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
