Introduction: The upper respiratory illnesses (URI) that result from immune dysfunction in elite sport pose a great threat to the training athlete. Nutritional adequacy is encouraged to prevent these illnesses; polyphenols in particular have been proposed to have immune modulating benefits to the consumer. Olive leaf extract (OLE) is a herbal supplement rich in polyphenols that has gained much anecdotal and in vitro evidence for its immune benefits. Methods: Twenty-nine secondary school aged athletes competing in the highest calibre of their team sport for their age and gender consumed either an olive leaf extract capsule or placebo for 9 weeks. Twice weekly subjective measures of upper respiratory illnesses were administered at the sites of the teams’ trainings, meetings or games. Periodic 24-hour written diet recalls were obtained from participants to ascertain nutritional adequacy from an immune perspective. Swab tests were performed for Influenza A & B, RSV and Streptococcus A. Results: OLE significantly reduced the number of sickness days spent burdened by an upper respiratory illness (OR = 0.72 (95% CI 0.56 – 0.93), p = 0.02). No difference was observed between URI incidence between treatment and control (OR=1.02 (95% CI 0.21 – 4.44), p > 0.99). OLE posed no benefit to secondary wellness outcomes such as fatigue and soreness, with unclear clinical inference outcomes. Nutritional quality was similarly adequate across both groups, with the exception of a deficit in carbohydrate intake. Conclusion: OLE may be opted for during periods of heavy training with the intention of reducing the number of days affected by an illness, returning the training athlete to competition faster. |
