Tittel

Effect of blueberry and red grape juice on plasma antioxidants, inflammation, oxidative- and muscle damage biomarkers in elite athletes practicing endurance training

Sammendrag

Background and aim: Intensive exercise of long duration increases blood levels of oxidative damage- and inflammatory biomarkers. Different polyphenols in blueberries and red grapes have antioxidant properties and prevent oxidative damage, thereby, contributing in prevention of different oxidative stress related diseases like cancer, stroke, cardiovascular diseases, neurodegenerative diseases and diabetes. The aim of our study was to study the effect of polyphenol-rich juice on the plasma antioxidants, inflammation, oxidative- and muscle damage- biomarkers in elite athletes practicing endurance exercise. Methods: The study is randomized, double-blind and followed a parallel design with 5-8 week intervention period. Norwegian male athletes competing in endurance sports at national team levels exercising 15 hours or more per week were recruited through Olympiatoppen. After washout period of one week, the participants were invited to give fasting blood samples and anthropometric measurements. The juice group consumed two boxes of European blueberry/red grape juices (2 x 330 mL) every day in the intervention period. The placebo group received a placebo drink (2 x 330 mL) every day with similar carbohydrate and energy amount as the juice. The participants registered their physical exercise every day during the intervention period. We have measured 35 different plasma/erythrocyte antioxidants including 12 different polyphenols, plasma total antioxidant capacity, 5 different plasma/erythrocyte oxidative damage biomarkers, marker for muscle damage, 23 different inflammatory markers in fasting blood samples taken before and after 5-8 weeks of intervention. Results: Among the antioxidants measured, polyphenols increased significantly in the juice group (p
