Effect of Acute Dietary Supplementation With Grape Seed Extract on Aortic Stiffness, Arterial Pressure, and Blood Vessel Dilation in Collegiate Obese Individuals at Rest

Obesity Clinical Trial

Official title:
Effects of Acute Grape Seed Extract Supplementation on Hemodynamics in Obese Males

Clinical Trial Summary

This study investigated if elevated BP and aortic stiffness characterized in obese individuals are attenuated following acute grape seed extract supplementation. It is hypothesized that acute dietary supplementation with grape seed extract attenuates aortic stiffness, systolic blood pressure, diastolic blood pressure, mean arterial pressure, and total peripheral resistance and these effects are partially due to reductions in peripheral vasoconstriction

Clinical Trial Description

Twenty men (obese = 10; normal body weight (NBW) = 10) participated in this study. Effects of placebo (PL: 600 mg) and GSE (600 mg) on systolic blood pressure (SBP), diastolic blood pressure (DBP), mean arterial pressure (MAP), heart rate (HR), stroke volume (SV), cardiac output (Q), total peripheral resistance (TPR), and AoS were compared 2 h after ingestion of GSE or PL on different days, one week apart. Arterial blood pressure was measured using a sphygmomanometer from a brachial artery at the level of the heart on chair. HR and SV were continuously measured using a non-invasive device (Physio Flow). CO was calculated by HR X SV. TPR was calculated by MAP/CO. ;
