Twenty-one older, overweight participants were randomised to 3 weeks of either beetroot juice concentrate or blackcurrant juice supplementation to test the effects on cutaneous microvascular reactivity during post-occlusive reactive hyperaemia (PORH). The study also tested whether the effects were maintained after 1 week from interrupting the supplementation. The peak hyperaemic blood flow and the PORH index were not different between the two interventions at the end of both supplementation and post-supplementation phases.
