Résumé
Rectal distension increases regulatory burden to autonomic nervous system in the brain. To determine the effect of rectal defecation on endurance performance and blood supply to the prefrontal brain and sub-navel regions of elite triathletes. Thirteen elite triathletes completed a cycling time trial (80% VO Defecation moderately decreased systolic blood pressure (-4 mmHg, Our results suggest that improved exercise performance after defecation is associated with greater blood availability to compensate deoxygenation in the prefrontal brain region during exercise. Further investigation is needed to examine the role of increasing sub-navel oxygen consumption in the performance improvement after defecation.

BACKGROUND
UNASSIGNED
Rectal distension increases regulatory burden to autonomic nervous system in the brain.
PURPOSE
UNASSIGNED
To determine the effect of rectal defecation on endurance performance and blood supply to the prefrontal brain and sub-navel regions of elite triathletes.
METHODS
UNASSIGNED
Thirteen elite triathletes completed a cycling time trial (80% VO
RESULTS
UNASSIGNED
Defecation moderately decreased systolic blood pressure (-4 mmHg,
CONCLUSION
UNASSIGNED
Our results suggest that improved exercise performance after defecation is associated with greater blood availability to compensate deoxygenation in the prefrontal brain region during exercise. Further investigation is needed to examine the role of increasing sub-navel oxygen consumption in the performance improvement after defecation.
