Brief summary

Background: Prior research performed by this group has reported that playing rugby increases the incidence and duration of URI compared with the general population, especially in elite schoolboys. In addition polyphenols, of note flavonoids, have been reported to decrease the incidence and duration of URIs but currently there is no research investigating the effect of OLE (a polyphenol supplement) on URIs in school aged athletes Objective: Determine if OLE supplementation decreases URI rates in high school athletes Setting: Autumn/Winter 2018 Participants: 50 healthy high school athletes Intervention: Either OLE or placebo tablet for two months Assessment: Completing a questionnaire twice a week for the duration of the intervention and three nasal swabs when they are identified as having a URI by the questionnaire Primary Outcomes: Incidence and duration of URI

Interventions

Olive Leaf Extract (OLE), equivalent of 7 grams of fresh leaf, given daily for two months Participants will be given the tablets and asked to return them at the end of the intervention period. The remaining tablets will be counted and measured as a percentage of compliance
