Clinical Trial Summary

Background:

The consumption of Energy Drinks (EDs) can acutely lead to negative side effects, such as raised blood pressure and impaired endothelial function. Nevertheless, they are sold worldwide and are often consumed before physical activity (PA). In contrast to the blood pressure elevating effect of EDs, PA leads to a reduction of blood pressure. The effect of ED consumption on blood pressure response during and after endurance training is currently unresolved.

Methods:

A total of 23 participants (eleven men, twelve women) were evaluated in the intervention study with a blinded Cross-Over Design. They consumed on two different days either 355 ml Red Bull (RB) or 355 ml Placebo (Pla) in randomised order. The peripheral (PBP) and central blood pressure (CBP) were measured before, during and after a 30-minute aerobic endurance training, by the Schiller BR-102 plus PWA device.
