No Evidence Of Stochastic Resonance In Postural Sway Response To Noisy Galvanic Vestibular Stimulation In Healthy Young Adults, Dominique Rice

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The transcutaneous application of a sub-sensory electrical stimulation to the vestibular afferents, known as noisy galvanic vestibular stimulation (nGVS), is thought to cause a reduction in postural sway at optimal amplitude intensities due to a mechanism known as stochastic resonance (SR). SR is a phenomenon whereby the addition of low amplitude noise to a non-linear system can be beneficial rather than detrimental. In humans, behavioral markers of SR in postural sway have been inconsistent, potentially due to insufficient power or false positives. Therefore, the main purpose of this study was to determine whether the frequency of observing SR-like effects improves …

The Wingate Anaerobic Test: A Comprehensive Literature Review And Update On Reference Values In Athletes, Caleb Christie

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Wingate Anaerobic test (WAnT) was developed in the 1970s as a measurement of lower extremity anaerobic power (Ayalon, Inbar, Bar-Or, 1974) and has long been used as a measurement tool in athletes, who are often defined by numbers. While numbers are not able to entirely predict or evaluate athletic ability, they are often used as a tool to predict or rate athletes. The WAnT has long been a gold standard in evaluating lower extremity power, which is a highly valuable aspect of many sprint and power-driven sports (e.g., hockey, football, or track and field). The WAnT was originally developed …

Utilization Of Protective Cultures To Reduce Late Gas Formation By Paucilactobacillus Wasatchensis, Ireland R. Green

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Cheesemaking is a process susceptible to defects caused by microbes not purposefully added by the manufacturer. While these bacteria are not a health concern, they can cause problems such as producing carbon dioxide inside the cheese. This can cause slits and cracks in cheese making cheese unsuitable for slicing. One such bacteria identified by cheese researchers at Utah State University and Weber State University is Paucilactobacillus wasatchensis. When present in cheese, it can cause gas formation by using galactose to supply its energy. In doing so, it takes this six-carbon sugar and converts it into a five-carbon sugar and …

Local And Systemic Effects Of Flavonoid Intake With Submaximal Cycling Exercise: A Randomized Controlled Trial, Stephanie Kung

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Moderate to high intensity endurance exercise is a known cause of exercise-induced gastrointestinal syndrome, a condition often associated with intestinal complaints such as discomfort, cramps, and diarrhea. Oftentimes, elevated intestinal inflammation and permeability (a “leaky gut”) are also observed. Previous research has shown that flavonoids, natural compounds found in many fruits and vegetables, may mitigate these exercise-induced effects. In particular, certain cocoa powders contain high levels of flavonoids, and chocolate milk is a good source of protein and sugars for sustaining intense activity. Thus, the purpose of this study was to evaluate the effects of a dairy pre-workout beverage, with …

When Healthy Turns Harmful: Increasing Understanding Of Potential Risk Factors And Approaches To Decreasing Orthorexic Behaviors, Elizabeth King

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Orthorexia Nervosa (ON) is a relatively new term used to describe individuals who place an excessive value on consuming a “pure” or healthful diet, so much so that their psychological, and potentially physical, health is negatively affected. ON is driven by a focus of consuming high-quality foods rather than limiting the quantity of food. This has sometimes been referred to as “clean eating”, or only consuming “clean” foods. A commonality between ON and other eating disorders (EDs) is that the behaviors are rooted in restriction, where an individual with ON would focus on restricting specific foods, or even entire food …

Effect Of High-Intensity Ultrasound On Bubble Dynamics, Oxidation, And Crystallization Behavior Of Fats, Juhee Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Partially hydrogenated oils (PHOs) provide desired texture, stability, and extended shelf life in food products. These types of lipids have been commonly used in food industry. However, the Food and Drug Administration (FDA) decided to remove generally recognized as safe (GRAS) status of PHOs in 2015 due to the association between PHOs and coronary heart disease (CHD), type 2 diabetes and other metabolic diseases. Hence, it is necessary to find alternative new healthy lipids or novel processing conditions that can be used to replace the functionality of PHO. Among the processing methods to be used in alternative PHOs fats, high-intensity …

Synergistic Effect Of High Intensity Ultrasound, Antimicrobial Compounds, And Uv-A Light On Microbial Quality Of Dairy Products, Bryce Rodney Hales

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Food spoilage and contamination remains a common problem within the food industry. Furthermore, the continued change of consumer demand and perspective on food quality and products has led the food industry and researchers to find new methods of food preservation. Many of these new methods hope to use non-thermal processes since thermal processes tend to decrease the overall quality of the final product. Some new non-thermal methods that have been looked at are the use of high intensity ultrasound (HIU), ultraviolet light, and the use of natural antimicrobials. In this study, UHT milk inoculated with either E. coli K12 or …

Improving The Specificity Of Vertical Stiffness Measurement In Depth Jump Landings, Miles Mercer

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Greater lower extremity stiffness has been shown to increase bilateral jump height through stretch-shortening cycle optimization. Currently, there are two established methods for estimating vertical stiffness (K_vert) of the human body, which is a variant of lower extremity stiffness. The validity of these methods for estimating K_vert in non-cyclical human movements has been questioned recently due to the complex physiological and neuromotor factors that support stiffness regulation in the muscle-tendon complex. The purpose of the present study was to improve the specificity of K_vert measurement using direct derivation of vertical ground reaction force (GRF) and center …

The Effects Of Trace Mineral Supplementation On Performance, Health, And Carcass Quality Of At-Risk Mineral Deficient Feedlot Cattle, Tevan J. Brady

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Morbidity in feedlot cattle due to disease is a common economical loss for feedlot producers. Utah is not typically considered a ‘feedlot state’, but there are several producers in the southern part of the state that specialize in receiving at-risk cattle. These cattle are at-risk because they are coming from areas known to be mineral deficient. Areas such as the western US, are known to be deficient in several trace minerals important in immune response. Therefore, it is critical that producers have an adequate plan to decrease the negative effects that this has on economic viability of their beef operations, …

It's About Time: Examining The Role Of Time Together And Perceived Stress In Couple Relationships, Rachel J. H. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Because stress is a common struggle in romantic relationships and because stress can spill over into couples’ interactions and affect their level of relationship connection, it is important to understand what can help couples adapt to stress and maintain meaningful relationships. Quality time together has been found to have positive effects on relationship outcomes overall. Additionally, family stress theory has posited that having sufficient resources can help couples adapt to stress and avoid a crisis situation. As such, time together was examined as a potential resource for couples to draw upon to adapt to the potential negative effects of perceived …

Effect Of Dietary Short And Medium Chain Fatty Acids In Murine Lethal Sepsis Model, David Son Dang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sepsis is defined as the presence of an infection in combination with systemic inflammation in a host. One of the detrimental results of sepsis is multiple organ failure which eventually leads to death. Lipopolysaccharide (LPS), an endotoxin that can be found on the outer surface of gram-negative bacteria, can be used as a model for sepsis. LPS present in the circulatory system of hosts can induce symptoms that are seen in patients during septicemia.

Previous studies have suggested that including milk fat in a diet may protect against a lethal dosage of LPS in rodents. Milk fat has a unique …

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Aphasia is an acquired neurogenic language disorder encompassing oral and/or written language expression and comprehension affecting an estimated two- to two to four million people in the United States, (Simmons-Mackie, 2018; National Aphasia Association, 2016). The primary aim of the current study was to investigate an option for targeted intervention as a follow-up to an Intensive Comprehensive Aphasia Program (ICAP). There is little research assessing maintenance of communication profile gains following conclusion of the ICAPs, and there are few options that exist as tailored ICAP follow-up programs or continued intervention guided by the ICAP principle features. To address this, a …

The Moderating Role Of Psychological Inflexibility In The Relationship Between Minority Stress, Substance Misuse, And Suicidality In Lgb+ Adolescents, Sean N. Weeks

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Adolescence is a difficult time, especially for those who do not identify as heterosexual (e.g., gay, lesbian, bisexual, asexual, pansexual; LGB+). Increased rates of substance abuse and suicidality are well documented outcomes that tend to be worse in the LGB+ adolescent community than in mainstream groups. Minority stress, the effect of unique stressors experienced by those in the LGB+ community explained by external and societal influences, has been accepted within the research community as a theory used to explain the health disparities seen in this group. This study proposed a possible further explanation, in addition to minority stress, that helps …

College students who are better able to manage stress are more successful than those who cannot. One method of coping with stress and anxiety is the practice of mindfulness. Mindfulness is the ability to be fully present in the moment, be aware of one’s mind, body, and …

The Role Of The Recently Deorphanized G-Protein Coupled Receptor, Gpr171, In Morphine Tolerance And Withdrawal, Leela Afrose

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Opioid analgesics, such as morphine, represent the gold standard pain killer and the most frequently used drugs for the treatment of moderate to severe pain. Despite being a potent analgesic, morphine has unwanted and dangerous side effects with repeated use, such as tolerance and withdrawal. Tolerance is a state when a person no longer responds to a drug and a higher dose is required to achieve the same initial pain relief. Withdrawal is a set of undesirable psychological and physiological symptoms that occur after someone stops taking a drug or reduces the dose. Morphine tolerance and withdrawal play a vital …

Are Effort And Helpfulness Ratings Of Session Activities Associated With Improved Outcomes In Web-Based Acceptance And Commitment Therapy (Act) For Caregivers?, Hannah R. Cragun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Family caregivers for people with dementia are providing care for up to ten years because people with dementia are living longer. This role can be demanding because the person with dementia can have behavioral and psychological symptoms that can be stressful for the caregiver to witness and manage. Acceptance and Commitment Therapy (ACT) in its traditional face-to-face format has strong scientific support in helping caregivers to be less depressed and better cope with the stress associated with taking care of their loved one. However, because caregiving is a time-demanding role, caregivers can struggle with accessing face-to-face therapy, making online ACT …

Despite increased use, people with disabilities continue to report barriers accessing public transportation services. Interestingly, little is known about these barriers at the regional transportation district level. The purpose of this study was to better understand the barriers and perceived accessibility of the Utah Transit Authority’s (UTA) public transportation system for individuals with disabilities living within the UTA service area.

Using an online survey, data were …

Piloting A Cooking Demonstration Curriculum For Dietetics Students, Jill Henderson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Cooking demonstrations are a unique and effective way to teach nutritional concepts and basic cooking skills in a community setting. They have been found to be beneficial for participants in attendance as they improve confidence in the kitchen, cooking skills development, and the promotion of healthier foods into the diet. Classroom learning facilitates critical thinking but does not necessarily provide a platform for hands-on learning. In planning and executing community-involved cooking demonstrations, students are able to connect content learned in the classroom to professional practice. Over the last decade the field of dietetics has involved more community-based programs designed to …

The Effects Of A Yoga Intervention On Reactive Balance In Older Adults, Haley M. Hayes
