Effect Of Long-Duration Standing And Sitting On Vascular Function, Zackary Vaughan

Health, Human Performance and Recreation Undergraduate Honors Theses

Background: An increase in sedentary lifestyle is a growing problem as it has a negative impact on vascular function leading to significantly higher risk of myocardial infarction and cardiovascular disease mortality. Both standing and sitting for extended periods of time affect endothelial function in lower leg vasculature. Flow-mediated dilation (FMD) and pulse wave velocity (PWV) are two variables that allow us to quantify endothelial function. Purpose: The purpose of this study was to compare the effects of long-duration sitting versus standing on lower body vasculature as assessed by PWV and FMD. Methodology: This study included 13 men and …

The Acute Effects Of Citrulline Malate And Bonded Arginine Silicate Supplementation On Vasodilation Of Young Adults, Jeffrey Rogers

Health, Human Performance and Recreation Undergraduate Honors Theses

Abstract

Background

Clinicians, professional athletes, and recreational athletes are interested in supplementation that up-regulates nitric oxide (NO) production in blood vessel endothelium, increasing arterial vasodilation. Benefits from these supplements include improvements in blood pressure, muscle hyperemia, and exercise performance. Citrulline Malate (CM) is a pre-workout ingredient, popular for its ability to increase exercise performance and blood serum concentrations of L-arginine, resulting in NO production. Recently, Inositol-Stabilized Arginine Silicate (ASI, Nitrosigine) has been added to many of the most popular pre-workout blends, following a group of studies showing ASI increases serum arginine and reduces post-workout muscle damage. Research has yet to …
