The Effects Of Dietary Capsaicin On Movement-Induced Hyperemia, Isabella S. Harelick, Valerie Chervinskaya, Kyle Heise, Melissa Severino, Meredith Georger, Zoe Fallon, Elisa Fioraso, Ben Melnick, Kira Pegues, Hashim Ghias, Justin Deblauw, Erin Davis, Siena Goebel, Will Quinn, Jillian Lang, Elena Shostak, Stephen Ives Facsm

International Journal of Exercise Science: Conference Proceedings

Cardiovascular disease (CVD) is the leading cause of death in the United States and affects men and women differently, highlighting the importance of understanding vascular regulation across both sexes. Regular consumption of dietary capsaicin (found in spicy peppers) has been associated with reduced CVD risk, potentially through improvements in vascular function. However, the mechanisms by which dietary capsaicin influences vascular health are not well understood. Passive limb movement-induced hyperemia (PLM) is a non-invasive technique used to assess vascular health. During PLM, a limb (typically the leg) is moved passively—without muscle contraction—by an external force, such as a researcher or mechanical …

Investigating The Effects Of Visual Feedback On Muscle Activity, Heart Rate, Rpe, And Perceptions Of Performance In Ballet Dancers, Lilah A. Duboff, Sarah Dipasquale, Stephen Ives

International Journal of Exercise Science

International Journal of Exercise Science 17(1): 1056-1067, 2024. Extreme postures and imbalances in neuromuscular activity may place classical ballet dancers at higher risk of injury. Dance studio mirrors provide visual feedback by which a dancer can self-correct their body position and alignment, but have been suggested to negatively impact kinesthetic abilities and decrease performance capabilities. Thus, we investigated the effects of a mirror on muscle activity of the quadriceps, heart rate (HR), rating of perceived exertion (RPE), and qualitative performance. A lack of visual feedback would increase muscle activity of the quadriceps, HR, and RPE, and decrease self-reported perception of …

Development Of An Enhanced Sampling Workflow To Accelerate Molecular Docking With Sparse Biophysical Information, Zachary Stichter

Masters Theses & Specialist Projects

Rapid docking of flexible biological macromolecules remains a significant open challenge in protein structure determination. While rigid docking is relatively simple with toolkits such as TagDock, a key obstacle to rapid flexible docking is the complexity and roughness of the free energy surface associated with protein conformational motion (often termed the many-minima problem), meaning conventional molecular dynamics methods do not effectively sample protein conformations near the interaction complex in accessible timescales. Methods such as metadynamics and replica exchange molecular dynamics exist to ameliorate this obstacle, yet these methods use nonphysical biases or random swaps to enhance sampling. In contrast, high …

Effect Of Dietary Flavonoids On Growth In Saccharomyces Cerevisiae, Vivian Rivera

Mahurin Honors College Capstone Experience/Thesis Projects

Plant foods contain a diversity of biologically active compounds called phytochemicals, produced by plant species as secondary metabolites. A phytochemical group known as flavonoids has received much scientific attention in recent times with respect to their antioxidative and anti-inflammatory roles. This investigation examined how quercetin and naringenin, the most common dietary flavonoids, affect growth potential of yeast under optimal and stress conditions (temperature, glucose, and oxidative stress). Using Saccharomyces cerevisiae as a model, a dose dependency effect of quercetin and naringenin was observed under optimal conditions when liquid cultures were treated with three different concentrations (75 μM, 150 μM, and …

Bilateral Differences In Vascular Stiffness And Blood Pressure Of Female College Tennis Players And Controls, Chanhtel E. Thongphok, Abena O. Gyampo, Anneli O. Ramolins, Elianna G. Hills, Claire E. Coates, Stephen J. Ives

International Journal of Exercise Science: Conference Proceedings

Vascular stiffness is highly correlated to cardiovascular disease (CVD) and has been attenuated by regular aerobic exercise in older adults. Additionally, body composition strongly predicts vascular stiffness and CVD risk. Previous research has documented that bilateral differences in shear stress lead to differences in vascular endothelial function in tennis players. However, whether this translates into bilateral differences in vascular stiffness and blood pressure remains to be elucidated. The SphygmoCor is a gold standard for assessing arterial stiffness but is not readily accessible. In comparison, the TicWatch GTH Pro, which uses the SphygmoCor algorithm to provide a cardiovascular health (CVH) score …

The Acute Impacts Of Resistance Training Performed With And Without Blood Flow Restriction On Lower Body Muscular Power, Justin Faller, Brian Thompson, Stephen Ives

International Journal of Exercise Science

International Journal of Exercise Science 16(6): 1320-1333, 2023. The American College of Sports Medicine recommends resistance training using at least 70% one repetition maximum to improve muscular strength and hypertrophy; however, these intensities may not be safe for all populations. A training technique that has been reported to elicit increases in strength and muscle size uses low intensity resistance training or low load training in combination with blood flow restriction (BFR) to the working muscle. Although the acute effects of BFR on muscle strength and size are well established, the effects of BFR on muscular power are not definitively known. …

The Effects Of Accessory Blood Flow Restriction Training On Muscle Size And Strength In Division Iii Soccer Athletes: A Preliminary Ecological Study, Kaitlyn Judd, Christian Morales, Megan White, Kate Wilkie, Justin Faller, Stephen Ives

International Journal of Exercise Science

International Journal of Exercise Science 16(6): 1244-1256, 2023. Blood flow restriction training (BFRT) uses occlusion during low-intensity resistance training (< 50% of 1-repetition maximum, 1RM) to reduce arterial blood flow and venous return, imposing greater metabolic stress but similar muscular hypertrophy and strength gains as high-intensity resistance training (HIRT). However, no study, to date, has incorporated BFRT in a collegiate strength and conditioning setting to assess ecological validity. We aimed to investigate the effects of adding 6-weeks of accessory BFRT or HIRT to NCAA Division III soccer players prescribed resistance training regimen on muscle strength and size. Male and female (n = 17) athletes were randomly assigned to complete biceps curls 2x/week under BFRT or control (HIRT), following regularly scheduled strength training. Bicep strength (1RM) and circumference (BC) were assessed at weeks 0, 3, and 6 (men only). In men, for BC no significant interaction of condition x time was observed (p = 0.861), though condition (BFRT vs Control, p = 0.025) and time (p = 0.024) were significant. For 1RM, there was no significant interaction of condition …
