The Effects Of Caffeine Ingestion On The Hemostatic Response To Simulated Firefighting Activities, Sierra Wassell

Showcase of Graduate Student Scholarship and Creative Activities

The leading cause of death among firefighters is sudden cardiac event, and it is acknowledged that most ischemic events are due to an occlusive thrombus formation. In addition, due to the demanding job requirements and shift work, firefighters are commonly known to overuse caffeine as an ergogenic aid. The purposes of this study were to examine the potential effects of caffeine on the hemostatic response to simulated firefighting activity.

The Effect Of Oral Contraceptives On Caffeine Metabolism And Cycling Performance, Annette M. Lemanski

Showcase of Graduate Student Scholarship and Creative Activities

This project objectives were to determine the effects of oral contraceptives and menstrual cycle on the benefits of caffeine supplementation for cycling performance. Seventeen recreationally trained female cyclists completed four trials consisting of 3 kilometer time trials. Subjects ingested either caffeine or a placebo one hour prior to each trial. The magnitude of the ergogenic aid of caffeine was compared between oral contraceptive users and eumenorreheic females. In addition, the effect of caffeine was compared across different phases of the menstrual cycle, specifically the follicular and luteal phases.

Validation Of Practical Tools To Identify Walking Cadence To Reach Moderate Intensity, Spencer F.C. Smith, Matthew A. Short, Martin Sénéchal, Danielle R. Bouchard

International Journal of Exercise Science

International Journal of Exercise Science 12(4): 1244-1253, 2019. It is recommended that adults get at minimum 150 minutes of moderate-to-vigorous physical activity in bouts of 10 minutes or greaterevery week. Walking cadence (steps per minute) is one easy way to estimate intensity required, however tools that claim to quantify walking intensity via walking cadence have not been validated in adults. We aimed to validate: 1- the accuracy of walking cadence measurement by the Piezo RxD pedometer, Polar Stride Sensor Bluetooth Smart foot pod, and Garmin Ant+ foot pod at different speeds and slopes and 2- the ability of the Piezo …

The Role Of Adaptive Immunity In Chronic Hypoxia-Induced Pulmonary Hypertension, Levi David Maston

Biomedical Sciences ETDs

Inflammation is a prominent pathologic feature in pulmonary arterial hypertension as demonstrated by pulmonary vascular infiltration of inflammatory cells, including T and B lymphocytes. However, the contribution of the adaptive immune system is not well characterized in pulmonary hypertension (PH) caused by chronic hypoxia (CH). Inflammatory cells, through various mechanisms, have the capability to increase pulmonary vascular resistance in various disease states. CD4⁺T cells have the potential to play a significant role in the disease process initiated by hypoxia. CD4⁺T cells are largely responsible for orchestrating downstream immune processes and are critical in focusing and amplifying …

Experimental Investigation Examining The Effects Of Acute Exercise On Implicit Memory Function, Paul D. Loprinzi, Morgan Gilbert, Gina Robinson, Briahna Dickerson

Faculty and Student Publications

© 2019, PsychOpen. All rights reserved. Emerging work suggests that acute exercise can enhance explicit memory function. Minimal research, however, has examined whether acute exercise is associated with implicit memory, which was the purpose of this study. Three separate experimental studies were computed (N = 120; Mean age = 21). In Experiment 1, participants were randomly assigned to either a moderate-intensity bout of acute exercise (15-minute) or engaged in a seated control task (15-minute), followed by the completion of a word-fragmentation implicit memory task. Experiment 2 replicated Experiment 1, but instead employed a higher-intensity exercise protocol. For Experiment 3, participants …

Post-Acquisition Processing Confounds In Brain Volumetric Quantification Of White Matter Hyperintensities, Ahmed A. Bahrani, Omar M. Al-Janabi, Erin L. Abner, Shoshana H. Bardach, Richard J. Kryscio, Donna M. Wilcock, Charles D. Smith, Gregory A. Jicha

Neurology Faculty Publications

BACKGROUND: Disparate research sites using identical or near-identical magnetic resonance imaging (MRI) acquisition techniques often produce results that demonstrate significant variability regarding volumetric quantification of white matter hyperintensities (WMH) in the aging population. The sources of such variability have not previously been fully explored.

NEW METHOD: 3D FLAIR sequences from a group of randomly selected aged subjects were analyzed to identify sources-of-variability in post-acquisition processing that can be problematic when comparing WMH volumetric data across disparate sites. The methods developed focused on standardizing post-acquisition protocol processing methods to develop a protocol with less than 0.5% inter-rater variance.

RESULTS: A series …

Effects Of Intertidal Position On Metabolism And Behavior In The Acorn Barnacle, Balanus Glandula, Kali Horn

Master's Theses

The intertidal zone is characterized by persistent, tidally-driven fluctuations in both abiotic (e.g., temperature, [O₂], salinity) and biotic (e.g., food availability, predation) conditions, which makes this a very physiologically challenging habitat for resident organisms. The magnitude and degree of variability of these environmental stressors differs between intertidal zones, with the most extreme physiological stress often being experienced by organisms in the high intertidal. Given that many of the fluctuating conditions in this environment are primary drivers of metabolic rate (e.g., temperature, [O₂], food availability), we hypothesized that sessile conspecifics residing in different tidal zones would exhibit …

Barbosa, Alana De Sena Souza, Marco Bergamin, Vitor E. Valenti, Julien S. Baker, Guilherme L. Shimojo, Jonato Prestes, Whitley J. Stone, Danilo Sales Bocalini, Rogério Brandão Wichi

International Journal of Exercise Science

International Journal of Exercise Science 12(2): 1198-1205, 2019. The physical demands of soccer combined with the rigor of the competitive season may have a substantial impact on autonomic modulation in field soccer athletes. The number of sudden death cases associated with soccer may be related to the physical training required to maintain performance and fitness, minimal time for recovery, and recurrent game participation. It is possible to identify individuals at risk of cardiovascular events by measuring heart rate variability (HRV), which is an indirect method for assessing autonomic activity. Therefore, the objective of this study was to analyze HRV before …
