Racial Differences In Cerebral Hemodynamics During Aerobic Exercise, Ziba Taherzadeh, Claire E. Kissel, Taha Alhalimi, Paul J. Fadel

International Journal of Exercise Science: Conference Proceedings

Young healthy non-Hispanic Black (BL) adults have an attenuated increase in blood flow to working skeletal muscle during exercise compared to non-Hispanic white (WH) adults. Cerebral blood flow also increases during exercise; however, previous work has mainly included WH adults. There are no studies investigating potential differences in cerebral vascular responses to exercise in BL adults. PURPOSE: To compare middle cerebral artery velocity (MCAv) and cerebral vascular conductance index (CVCi) during exercise in BL adults to WH adults. We tested the hypothesis that BL adults have a blunted increase in MCAvmean and CVCi response during light and moderate intensity …

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

International Journal of Exercise Science: Conference Proceedings

Family history of hypertension (FHH), being an unmodifiable risk factor, increases probability of developing hypertension and other cardiovascular diseases. The prevalence of hypertension in Hispanic/Latino (H/La) males is 50.3%, while it is 48.9% in non-Hispanic white (NHW) males and 57.5% in non-Hispanic black (NHB) males. Among adolescents aged 8 to 17, H/La youth has the highest incidence of hypertension as compared to all other races. It is evident that young normotensive adults with positive family history of hypertension (+FHH) exhibit exaggerated exercise pressor response. Additionally, a higher sympathetic activity to cold pressor test (CPT) was found in normotensive NHB adults …

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 Feb 2024

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 …

The Effect Of Menstrual Phases On Salivary Markers Of Stress And Body Composition, Josey Walker, Nathan Sutton, Matthew J. Mcallister

International Journal of Exercise Science: Conference Proceedings

Women have been historically excluded in physiology research due to the assumption that the menstrual cycles influence physiological biomarkers. Research has shown that cortisol concentrations are higher during the follicular phase compared to the luteal phase of the menstrual cycle. In addition, morning cortisol concentrations have been shown to be significantly higher in the morning compared to evening. However, salivary a-amylase (sAA) and secretory immunoglobin-A (SIg-A) have not been researched across the menstrual cycle. sAA is an indicator of sympathetic nervous system activation and is sensitive to acute stress. SIg-A is an antibody that is also an indicator of chronic …

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: …

International Journal of Exercise Science: Conference Proceedings

Body volume (BV) indicates the total 3-dimensional (3D) space an individual occupies. BV is either used alongside body mass in density-based two-compartment models or in conjunction with other body components in multi-compartment models to estimate body composition (BC). BV estimates are typically produced by costly laboratory methods, such as hydrostatic weighing or air-displacement plethysmography (ADP). However, more accessible options are emerging. Smartphone-based 3D scanning uses the phone’s built-in camera to provide a BV estimate in a time-efficient and cost-effective manner. However, few investigations have validated this method against an accepted laboratory technique. PURPOSE: To determine the validity of BV from …

Does 24-48 Or 48-96 Promote Better Rem Sleep Within Firefighters?, Ernesto Balderrama Jr, Raquel J. Cavazos, Cheyenne Martinez, Bryan G. Meek, Hussien K. Jabai, Vipa Bernhardt, Michael D. Oldham

International Journal of Exercise Science: Conference Proceedings

A firefighter’s work schedule can be very demanding regardless if they work 24 hours followed by a 48-hour time off schedule or a 48-hour on followed by a 96-hour time off. Rapid Eye Movement (REM) sleep could be the deciding factor of how well a firefighter can perform following a certain work schedule. REM sleep is associated with the mental activity of dreaming; an individual averages 20-25% REM sleep of their total sleep time (Carskadon & Dement, 2005). REM is important for recovery because it can impact cognitive functions such as impulse control and decision making (Brunet, et al, 2020). …
