Timed New Zealand blackcurrant juice (BJ) consumption inhibits platelet monoamine oxidase-B (MAO-B) activity. Platelet MAO-B activity was measured in participants who had consumed either a placebo (PLA) or BJ drink 1 h prior to performing a low impact walking exercise. Platelets from blood collected at baseline (filled bars), pre- (unfilled bars) and post- (hatched bars) exercise were measured for MAO-B activity using commercial Amplex® Red Monoamine-B assay kit. Results are expressed as mean ± SEM, n = 20 individuals per group. ^*p < 0.05 and **p < 0.01 represents statistical difference from baseline and pre-exercise values respectively within the PLA or BJ groups
