Description of intervention(s) / exposure
The intervention will be a Polyphenol-Rich Sugarcane Extract (PRSE) in a sports beverage. PRSE is a polyphenol-rich extract of sugarcane molasses. This beverage will be provided for 2 weeks to the subject. The dose is 10% w/v and subjects will receive 540 mL per day (2 X 270 mL, one at AM one at PM) during the intervention time. At the end of intervention time the participants will be subjected to a heat stress trial where they will run in 35 degrees of Celsius for 2 hours at 60% maximum volitional effort. During the intervention time the participants can continue with their daily routine. On the last day of intervention (the day before the exercise trial) they will be required to adhere to a low FODMAP diet for 24 hours and during the breakfast of the exercise trial day. During this trial they will be receiving 1 bottle (270 mL) of treatment drink pre-exercise at 0 minutes and PRSE containing gel packs every 20 minutes with 160 mL of water until 80 minutes. At 90 minutes they will receive a dual sugar drink consisting of 10 g of lactulose and 2 g of rhamnose along with 150 mL of water. During this protocol we will collect faecal samples and blood samples to measure biomarkers. i.e., Cortisol, Intestinal Fatty Acid Binding Protein (I-FABP), Interleukin (IL)-1ß, IL-1ra, Tumour Necrosis Factor alpha (TNF-a), IL-6, IL-8, and IL-10, sCD14, Short Chain Fatty Acids (SCFA) in faecal matter and plasma, metabolomics, Blood Glucose (BG), plasma bacterial DNA concentration, total and differential leukocyte cell count, plasma osmolality. The adherence to the protocol will be confirmed by self-reporting. The washout period between two treatments will be 2 weeks.

Summary
Brief summary
Exercise induced stress is common amongst many activities within health care, security, industry and sport. It has consistently been associated with increased inflammation, gastrointestinal disturbances, gastrointestinal symptoms and loss of appetite, resulting in an inability to maintain work-output and/or withdrawal from activity; constituting both a productivity and financial burden. The mechanism responsible for exercise-induced inflammation, and gastrointestinal symptoms appears to be multi-factorial in origin, but ultimately leads to gut surface damage and leakage, and an overall reduction in food and fluid intake. Increased gut leakage during exercise has also previously been linked to subclinical symptoms, heat illnesses, and other clinical manifestations such as exercise-associated bacteraemia. PRSE is a polyphenol-rich extract of sugarcane molasses. Polyphenols are naturally occurring substances in plants, known for their potential health benefits. We will explore the ability of PRSE to reduce exercise-associated gastrointestinal disturbances, including symptomology.
