Acute Effect of Energy Drinks on Vascular Function
The purpose of this study will be to examine the acute effect of commercially available
energy products on endothelial function, arterial stiffness and thrombosis in healthy young
males.
energy products on endothelial function, arterial stiffness and thrombosis in healthy young
males.
The use of energy products has significantly increased in the last few years and is
especially high among young men. The present study will compare the acute effect of a
commercially available energy drink, energy gum, coffee and control beverage on endothelial
function, arterial stiffness and circulating markers of thrombosis, inflammation and
oxidative stress.
