Prehypertension Clinical Trial
Official title:
Effect of 7 Days of Grape Seed Extract Supplementation on Cold Pressor Test and Muscle Metaboreflex in Individuals With Elevated and Stage 1 Hypertension
This study aimed to assess the effect of the supplementation with grape seed extract (GSE) on blood pressure during static handgrip exercise and muscle metaboreflex in individuals with elevated and state 1 hypertension.
Muscle metatoreflex (MMR) has been known to play an important role in adjusting hemodynamic responses during exercise. The reflex increases sympathetic activity to heart and blood vessels to increase blood supply to contracting skeletal muscles. On the other hand, studies demonstrated that abnormal cardiovascular responses occurred by the overactive MMR in pathological conditions such as hypertension, diabetes, and congestive heart failure. Excessive blood pressure (BP) responses to exercise induce cardiovascular events such as stroke, heart attack, and coronary artery disease. Previously, a study found that dietary supplementation with grape seed extract (GSE) reduced BP response to dynamic exercise in individuals with elevated and stage 1 hypertension (ES1H) and associated with peripheral vasodilation. However, mechanisms underlying this phenomenon are not clear. Purpose: therefore, the purpose of this study is to investigate whether chronic dietary supplementation with GSE can decrease BP responses to exercise and this observation is associated with reduced MMR. Methods: 12 ES1H males were studied. Changes in cardiac output (Q), mean arterial pressure (MAP) and total peripheral resistance (TPR) were compared between the GSE and placebo supplementations during static handgrip exercise (SHE) and post exercise muscular ischemia (PEMI). Participants completed 3 min of SHE at 40% of MVC followed by 2 min of PEMI. ;
