Effect of New Zealand Sujon blackcurrant on cardiovascular responses during cycling in triathletes

Background Anthocyanin is a component known to induce vasorelaxation and vasodilation in rat aortic rings [1] and is present in high amounts in New Zealand Sujon blackcurrant. During typing work in humans, an activity of low intensity, peripheral blood flow was increased by blackcurrant intake [2]. It is not known whether anthocyanin would affect the cardiovascular responses at different exercise intensities. We examined the effect of 1week Sujon blackcurrant powder supplementation on cardiovascular responses at low, moderate and high intensities of trained triathletes.
