A single dose of microencapsulated cocoa supplementation attenuated eccentric exercise-induced endothelial dysfunction.

In the present study, it was evaluated whether microencapsulated cocoa supplementation could attenuate endothelial dysfunction caused by eccentric exercise in healthy subjects. Thirteen volunteers were enrolled in this double-blind, placebo-controlled, crossover study. Flow-mediated dilatation (FMD), blood flow and muscle O saturation (StO) were evaluated by ultrasound and near-infrared spectroscopy (NIRS), respectively, before and after microencapsulated cocoa supplementation.
