Summary

Jamie Pugh is a post-doctoral research at Liverpool John Moores University. During his PhD and current work, he has looked at the effect exercise can have on the gastrointestinal system and in more recent work, looked at the effects probiotic supplementation can have on endurance athletes. He has also worked as a consultant nutritionist and physiologist for a number of professional teams and extreme endurance athletes.

In This Episode We Discuss
The range and severity of symptoms athletes experience
Causes of symptoms: physiological, mechanical and nutritional
Individual variation in susceptibility to symptoms
Lack of association between gut “damage” and symptoms experienced
GI distress outside of endurance sport
Maximal rates of glucose ingestion: higher than previously thought?
Effect of glutamine supplementation
Effect of probiotic supplementation
Effect of low FODMAP diets
Practical steps for practitioners and athletes to mitigate risk
