It was demonstrated that acute dietary supplementation with GSE reduced arterial blood pressure via reduction in Q in obese individuals. However, no studies have investigated the chronic effects of dietary GSE supplementation on hemodynamic responses during exercise. Given the fact that obesity is associated with an impaired function of eNOS, the effect of chronic dietary GSE supplementation on abnormal blood pressure response to exercise and aortic stiffness (AoS) needs be elucidated. Thus, it is hypothesized that GSE decreases systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), Q, and aortic stiffness at rest and during exercise. This study would determine that this supplementation may be used as a non-pharmacological intervention to prevent incident hypertension and cardiovascular events during exercise via enhanced endothelial function.
