Investigating a Natural Antioxidant Food Product on Oxidative Stress in Recreationally Active Participants

The aim of this study is to investigate the short term use of olive extract polyphenols on markers of oxidative stress in response to acute endurance exercise in recreationally active, healthy volunteers.The study will be conducted under laboratory conditions following a 16 day supplemental period. Participants will be required to attend the laboratory for a pre-screening/familiarisation trial followed by assessments PRE (baseline, days 1,2) and POST intervention (days 18,19). Across the intervention, participants will maintain habitual dietary intake/ exercise training. Additionally participants will be randomised in a double-blinded manner to either a placebo or antioxidant-rich supplementation (olive extract water). It is hypothesised that the polyphenols (antioxidants) found within olive extract drink will enhance markers of recovery to an endurance exercise bout compared with the placebo drink.
