Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
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.
