Blood Pressure Variability In Young Male Adult Habitual Vapers, Rie V. Conley, Claire E. Kissell, Ziba Taherzadeh, Danny Dubroy, Benjamin E. Young, Ziyad Ben Taleb, Paul J. Fadel

International Journal of Exercise Science: Conference Proceedings

The use of e-cigarettes (i.e., vaping) has risen dramatically in the last few years. Vaping is more appealing and accessible to young people than traditional smoking. The ease of use can increase the frequency of vaping, which may increase the amount of nicotine consumed. Nicotine is a potent vasoconstrictor that may also affect blood pressure (BP). Indeed, previous studies have shown that traditional cigarette smoking increases BP variability. This is noteworthy because elevated BP variability has been shown to predict future development of cardiovascular disease. However, whether habitual vaping influences BP variability remains unknown. PURPOSE: To test the hypothesis …

Relationship Between Intestinal Permeability And Microvascular Responses In A High-Risk Hispanic Population Of The Rio Grande Valley, Sophia M. Moreno, Alissa Olvera, Abigail Gomez, Ryan Russell, Melody Cantu, Andrea Toledo, Yu Lun Tai

International Journal of Exercise Science: Conference Proceedings

The Rio Grande Valley (RGV) has ~3x higher rates of diagnosed cardiovascular disease (CVD) and type 2 diabetes (T2D) than the US, which combine to be the leading cause of preventable death in the developed world. Microvascular blood flow (MBF) responses are an early indicator of vascular insulin resistance, and is blunted with obesity, T2D, and those at high risk for T2D. We have previously shown that apparently healthy people in the RGV display impaired MBF responses, helping explain the disparities noted with chronic disease. However mechanisms explaining this early vascular insulin resistance remain unexplored. Recent studies indicate that increased …

Exercise Pressor Response In Hispanic Adults With Family History Of Hypertension, Ashlesha D. Dalve, Justo Perez Iii, Ruby A. Nyarko, Jasdeep Kaur
