Timed consumption of New Zealand blackcurrant juice (BJ) modulates blood lactate but not glucose levels. Blood glucose [a] and lactate [b] levels was measured in participants who had consumed either a placebo [PLA] or BJ drink 1 h prior to performing a low impact walking exercise. Blood glucose or lactate collected at baseline (filled bars), pre- (unfilled bars) and post- (hatched bars) exercise was measured using either HemoCue® Glucose 201 or Arkray Lactate Pro™ 2 biosensors, respectively. 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 each group
