Modulation of systemic oxidative stress and inflammatory markers after strenuous exercise. [A] Plasma oxidative capacity, [B] protein carbonyls, [C] creatine kinase or [D] interleukin (IL)-6 were assessed immediately before (pre) and then 12, 36 or 60 hours after 300 eccentric contractions of the quadriceps under control (♦) or blueberry (■) conditions. Results are expressed as mean ± standard error of percentage change from pre-eccentric exercise measurements. * P < 0.05 represents significant time difference from pre-exercise levels and § P < 0.05 represents significant treatment (blueberry) and time interaction, n = 10 volunteers.
