Study & Design

Study Type: Interventional

Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
Gut permeability by urinary excreiton of non-matabolisable sugars (lactulose and rhamnose) over a 5 hour period (in which all urine is collected) after the oral ingestion of these test sugars.

Secondary Outcome Measures

Name	Time	Method
Maximal oxygen consumption (VO2max); Core body temperature during exercise; Heart rate, subjective rating of perceived exertion, gas exchange (oxygen consumption and carbon dioxide output) during exercise; Full blood count, blood lactate, and blood glucose concentrations pre and post exercise trials (2 d and 14 d supplementation points in each arm).
