Clinical Trial Summary

During a multi−week expedition to the Himalaya, we aim to investigate i) whether dietary supplementation with carbohydrate drinks and gels can improve physical performance; and ii) the underlying mechanisms for any observed changes in performance.

We hypothesise that i) carbohydrate supplementation will improve physical performance; and ii) the underlying mechanism of this improvement in performance will include maintenance of body glycogen (sugar) stores, prevention of dehydration and decrease in the incidence of acute mountain sickness.
