Exercise-induced GI distress is similar in youth vs adult athletes 😮💨
Management strategies are therefore applicable.
Exploration of Exercise-Induced Gastrointestinal Syndrome in Endurance-Trained Adolescents: Is There Cause for Concern in Regard to Ultra-endurance Event Participation
Study Details
This new study recruited 12 youth (≤ 18y) and twelve adult (≥ 30-50y) endurance athletes 🫁
Participants completed 3hr of treadmill running at 60% VO2max followed by 2hr seated recovery 🏃♂️
Blood samples, subjective markers and feeding tolerance were assessed during the study to assess gastrointestinal effects 🔍
Key Findings
There was no difference in pre-to-post-exercise concentrations of…
❎ plasma cortisol
❎ elastase
❎ I-FABP
❎ sCD14
❎ TNF-α
❎ IL-10
…between youth and adult athletes.
Youths had higher total leukocyte and neutrophil counts in response to exercise 🩸
Adults reported higher upper-GI symptom severity during exercise 🫧
No other differences were observed in exercise-associated gastrointestinal symptoms (Ex-GIS) or digestion time between groups ❌
Conclusion
The pathways of EIGS in response to exercise do not substantially differ in youth vs adult athletes 🙅♂️
Therefore, GI symptom management strategies for adult athletes are likely transferable to youth athletes ✅
