The effects of four weeks of BRJ consumption or PLA on FMD. Beetroot juice consumption increases FMD responses in healthy older adults. Both (A) uncorrected and (B) allometrically scaled data are expressed as mean ± SD and individual data for uncorrected data. * Significance shown for comparisons within treatment allocations of the change between baseline, week 2 and week 4, p < 0.05 for the Bonferroni post hoc test. BRJ = beetroot juice; FMD = flow-mediated dilatation and PLA = placebo.
