Gastrointestinal Distress in Ultrarunning

This chapter explores research on gastrointestinal (GI) distress among ultramarathon participants, particularly at the Western States 100. It discusses the interplay between nausea, endotoxemia, and factors like hydration, nutrition, and blood flow dynamics during intense exercise. The findings aim to enhance understanding of the physiological challenges athletes face and the potential underlying causes of GI symptoms in endurance sports.
