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 …

Examining The Effect Of Exogenous Ketone Supplement On Indices Of Peripheral Vascular Health/Function, John Kolade, Alison Ortiz, Prarthi Shah, Ken Perry, R. Matthew Brothers

International Journal of Exercise Science: Conference Proceedings

Cardiovascular disease (CVD) remains the leading cause of death in the US and worldwide. The risk for and prevalence of CVD are elevated by various factors including impaired micro- and macrovascular function. Associated mechanisms are multifactorial but are related to elevated oxidative stress and/or inflammation which contribute to reduced nitric oxide bioavailability and ultimately vasodilatory reactivity. Ketogenic diets, commonly used as a strategy to lose weight and improve health, have been reported to improve mitochondria function, as well as antioxidant and inflammatory status. To the best of our knowledge, the effects on vascular function are less understood. PURPOSE: This …

Effects Of Continuous Aerobic Exercise On Skeletal Muscle Atrophy Induced By Heart Failure, Carolina Tonon, Bertha F. Polegato, Quinten Pigg, Dillon Harris, Aaron Garcia, Daniela S. Inoue, Mariana Janini Gomes

International Journal of Exercise Science: Conference Proceedings

Heart failure is a common and severe disease that worsens morbidity, mortality, and quality of life. One of the clinical manifestations of heart failure is peripheral muscular atrophy, whose presence impacts the prognosis of heart failure patients. Inflammation is one of the main mechanisms related to muscle atrophy. We hypothesized that inflammation, through excessive activation of the Nlrp3 inflammasome, would be tightly associated with skeletal muscle atrophy induced by heart failure. Additionally, aerobic exercise, well known for its anti-inflammatory action, would counteract this condition in a rat model of heart failure. PURPOSE: We aimed to evaluate the effects of continuous …

Short-Term Cd8+ T Cell Depletion Results In Blunted Liver Inflammation In Old Mice, Konner J. Terrebonne, David J. Buckley, Blessy Joseph, Sunita Sharma, Daniel W. Trott

International Journal of Exercise Science: Conference Proceedings

Advanced age is associated with an increase in basal inflammation of the organs. Previously we have found that T cells accumulate in the liver of old mice. A large proportion of these cells are CD8+ and produce inflammatory cytokines. We have previously demonstrated that CD8+ T cell depletion results in improved glucose tolerance in old mice. However, the mechanisms by which CD8+ depletion improves glucose tolerance is unclear. Therefore, we sought to determine whether pharmacologic CD8+ depletion would result in decreased liver specific inflammation in old mice compared to their old CD8+ intact counterparts. PURPOSE: To test the hypothesis …

Nutrition Able: A Lecture-Based Intervention To Promote Nutritional Literacy About Protein Intake In Women, Jeffery Bolte, Alejandra Garcia, Jacob Abalos, Jakson Johnson, Alex Joyce, Christopher Hinds, Jared Tuttle, Jeff Svec

International Journal of Exercise Science: Conference Proceedings

Sport performance is influenced by sport-specific requirements for body composition. One major predictor of body composition is protein intake. Higher protein intake tends to cause leaner body composition relative to lower protein intake, especially during caloric deficit. In Bexar County, ~72% of the adult population is overweight/obese and 15.5% are diabetic. This suggests that high protein diet could be a high leverage option in the San Antonio population for optimizing body composition for sport performance. Furthermore, late life sporting activity and protein intake is a primary method for mitigating sarcopenia, osteoporosis, fractures, and accidental death in post-menopausal women. PURPOSE: …
