A Comprehensive Examination Of Age-Related Lower Limb Muscle Function Asymmetries Across A Variety Of Muscle Contraction Types, Kylee Heap

All Graduate Reports and Creative Projects, Fall 2023 to Present

Previous research has found that lower limb muscle asymmetries increase with age and are linked to fall and injury risks. However, past studies lacked a wide variety of muscle function modes and measures as well as comparison to a comparable young aged group. The purpose of this study was to examine age-related lower limb muscle function asymmetries across a variety of muscle contraction types and velocities in young and old adults. Lower limb muscle balance, strength, power, and velocity were evaluated with concentric, isometric, isotonic, and eccentric muscle actions during a single-leg stance test and on single- and multi-joint dynamometers …

Monitoring of an athlete’s fatigue status helps identify the need to adjust one’s training program, identify injury risk, and help attain an athlete’s peak performance when it is most advantageous for them. More research is warranted that examines the effects of a comprehensive set of jump parameters to track recovery from muscle impairing exercise. This study focused on the onset of muscle soreness through eccentric resistance exercise. Purpose: The purpose of this project was to examine the efficacy of force plate …

Effects Of Blood Flow Restriction During Acute Multi-Joint Eccentric Exercise On Muscle Recovery, Cody Fisher

All Graduate Reports and Creative Projects, Fall 2023 to Present

Blood flow restriction (BFR) exercise has become an increasingly common modality due to evidence that it may yield positive muscle-related effects from low-intensity exercise. However, eccentric-only exercise in a multi-joint format has not yet been investigated in regard to the BFR influence on muscle recovery characteristics. The purpose of this study was to assess muscle recovery responses via isometric peak force (PF), soreness (i.e., VAS, PPT, PPD), and functional power (i.e., SLHD) following a 5-minute low-load multi-joint eccentric exercise bout with or without blood flow restriction. Thirty participants were randomly assigned into either an eccentric-only (CON) or an eccentric BFR …

It also highlighted participants’ preference for having nutrition education.

To overcome these challenges, the …

Evaluating The Effects Of Ketamine On Cognitive Flexibility In Rats Using A Probabilistic Reversal Learning Task, Anthony N. Nist

All Graduate Theses and Dissertations, Fall 2023 to Present

Depression is one of the most debilitating and widespread mental health conditions in the world today. Drugs that are traditionally prescribed to combat depression are flawed in several ways, and because of this, new treatments are needed. One drug that seems capable of overcoming the limitations of traditional antidepressants is ketamine. In clinical research, a single dose of ketamine can significantly reduce symptoms of depression quickly, its effects may last for weeks to months, and its side effects appear to be limited and relatively harmless. However, clinical research is ongoing, and more research is needed to fully understand ketamine's beneficial …

Dominant Cognitive Strategy In Aphantasia, Sarah N. Pope

All Graduate Theses and Dissertations, Fall 2023 to Present

The purpose of this research was to explore the impact on thinking when an individual is not able to "see with a mind's eye." This is known as aphantasia and is the reduction or absence of visual imagery, which can have large impacts on problem solving and remembering one's own past. The current study examines these impacts by exploring the different ways in which thinking may occur, verbal-analytical, visual imagery, spatial imagery, and how a one's dominant thinking strategy affects performance on a paired work task, a mental rotation task, and an object memory task. Comparing those with typical imagery …

Relative Hepatotoxocity, Carcinogenicity, And Toxicogenomics Of Select Dehydropyrrolizidine Alkaloids In Mice, Michael J. Clayton

All Graduate Theses and Dissertations, Fall 2023 to Present

Dehydropyrrolizidine alkaloids are arguably the most important plant derived toxins in terms of impact on human and animal health. Dehydropyrrolizidine alkaloids are a large group of chemically related compounds found in 3% of flowering plants worldwide. Human exposure occurs from ingestion of herbal products including teas supplements or contaminated grain. Animals are exposed through contaminated feed or grazing. There are at least 350 identified toxic PAs, from more than 6,000 plants. The toxins primarily cause liver damage, but some are proven to cause cancer. Indidvidual dehydropyrrolizidine alkaloids vary in their toxic effects. Riddelliine is the only dehydropyrrolizidine alkaloid with extensive …

Design Guidelines For Homeless Shelter And Resource Center Site Plans, Samuel Johnson

All Graduate Reports and Creative Projects, Fall 2023 to Present

Homelessness is one of the most pressing humanitarian issues facing the country today. Lack of affordable housing, among many other complicating factors, have led to many cities scrambling to find both short-, middle-, and long-term solutions to the issue. The Covid-19 pandemic added a disruption in services, critical record-keeping, and data-gathering, which has further confounded experts looking for an effective path forward. As it stands, there is a significant gap in academic research addressing best practices for shelter site design, particularly as it relates to landscape. The role of landscape and greenspace within and around a shelter is not well …

Reaction Time Under Limited Vision With Cognitive Challenge In Individuals With Anterior Cruciate Ligament Reconstruction, Hsuan Bonny Lu

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

The anterior cruciate ligament (ACL) rupture is a common sports injury. ACL reconstruction (ACLR) is a necessary treatment for individuals to return to competitive sports. However, a high rate of secondary injury occurs when individuals return to sport. Past research has shown that ACLR impairs physical performance, including reduction of force generate against the floor under the injured leg, changes in the gait pattern, and a loss of knee stability. While structural changes following ACL injury can leave the knee joint less stable, neurophysiological changes following ACL injury represent one potentially important mechanism underlying the performance deficits. Healthy individuals rely …

Patient-Therapist Congruence On Aspects Of The Therapeutic Alliance In Psychotherapy For Medically Unexplained Symptoms, Sarah Daehler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Medically unexplained symptoms (MUS) are physical symptoms that cannot be explained or are not sufficiently explained by medical examination. These symptoms most typically present as pain or other discomfort, and are associated with significant psychological distress, healthcare utilization, and disability. Both psychologists and medical professionals have struggled to treat this population, and MUS patients have noted their dissatisfaction with the care they receive. The present study analyzed a sample of 174 patient-therapist dyads to explore the role of congruence, or agreement, on aspects of the therapeutic alliance in therapy for MUS as congruence research has not yet been conducted in …

Prefrontal Activation During Inhibition Of A Balance Recovery Step, Ezinne Abugu

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

The ability to quickly step is an important strategy to avoid a fall. However, real-world settings often constrain a stepping path. Such constraints necessitate response inhibition to prevent an inappropriate step and select a new course of action to ultimately recover balance. The present study investigated neural mechanisms that underlie this ability to stop a highly automatic balance recovery step. In the field of cognitive neuroscience, response inhibition has typically been researched using focal hand reaction tasks performed by seated participants. This approach combined with neuroimaging has revealed a neural stopping network, which includes the right Inferior Frontal Gyrus (right …

Relationships Between Muscle Characteristics And Step Outcomes In Young And Old Adults, Kareem Abubukker

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

Background: Falls are a primary cause of mortality and morbidity in older adults. In an effort to assess falls, a number of studies have measured neurological, biomechanical, and neuromuscular function in relation to fall risk. Despite efforts, falls continue to affect the older adult population leading to subsequent impaired mobility and function. Multiple factors contribute to fall risk among older adults, however, a factor that has shown a consistent relationship with the prevalence of future falls is reduced muscle characteristics. Moreover, the ability to rapidly accelerate a limb, as captured by rate of power development (RPD), rate of velocity development …

County Characteristics And Opioid Mortality Rates In The United States, Baksun Sung

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Opioid overdose deaths are not equally distributed across the United States. While some areas have a less severe problem with opioid abuse, others face serious challenges, which are affected by various social factors. To address that question, in Chapter 1, I investigate how opioid mortality trends differ according to opioid types, race, and region to identify susceptible populations and areas. In Chapter 1, I contend that synthetic opioid is a main trigger for the current opioid epidemic and that the epidemic is concentrated among blacks and in the Eastern United States. Next, the following studies examine how varying social vulnerabilities …

Undergraduate Honors Capstone Projects

The purpose of this paper may be divided into two parts. The first part was a literature review that sought to determine the most common risk factors for developing a urinary tract infection in nursing homes, as well as to identify evidence-based practice interventions for decreasing UTI rates within that specific patient population. The second part consisted of a case study that sought to apply the principles gathered from the literature review to the UTI logs of a deidentified local nursing home. It was found that indwelling urinary catheters and age are the two most common precipitating risk factors for …

Speech Intelligibility Assessment: Predicting “Noncompliant” Listener Behavior, Briggs Kroff

Undergraduate Honors Capstone Projects

Purpose: When researching speech intelligibility among people with dysarthria, convenience sampling has typically been used to recruit listeners. A new online crowdsourcing method, Mechanical Turk (MTurk), results in ecologically valid results, but outlier results are often removed from the analysis and considered "noncompliant". This study aims to examine whether there is a relationship between age, gender, speech/language/hearing impairment, and whether someone is "noncompliant".

Methods: 16 speakers, both with and without dysarthria, were recorded while they read prewritten sentences. Research participants found through MTurk then listened to the sentences and transcribed them. They also were asked questions including their …

Effects Of Imu Sensor Location And Number On The Validity Of Vertical Acceleration Time-Series Data In Countermovement Jumping, Dianne Althouse

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

Many devices are available for measuring the height of a CMJ. An inertial measurement unit (IMU) measures linear acceleration, orientation, and angular velocity. As an alternative to using IMU estimates of flight time, CMJ height could be estimated by integrating the IMU time-series signal for vertical acceleration to derive CMJ take-off velocity in order to track whole-body center of mass (WBCoM) movement, yet this approach would require valid IMU acceleration data. Thus, the purpose of this study was to quantify the effects of IMU sensor location and number on the validity of vertical acceleration estimation in CMJ. Thirty young adults …

Association Between Visuomotor Skills And The Effects Of Stroboscopic Vision On Depth Jump Performance, Riley Welch

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

The reactive strength index (RSI) is a popularized method of evaluating depth jump performance. Performance in anticipation of ground impact is influenced by the proprioceptive, vestibular, and visuomotor systems through multisensory integration. The contribution of vision to depth jump performance has been studied through use of stroboscopic goggles, but no study has evaluated which visuomotor skills may be a predictor for DJ performance. The purpose of this investigation was to evaluate the association between visuomotor skills and the effects of stroboscopic vision on DJ performance. Participants consisted of 9 female and 13 male college aged adults. DJ performance was evaluated …

Comparative Effects Of Eccentric Overload Training On Muscle Function Measures When Combined With Aquatic Plyometric Training, Cassidy Weeks

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

Although there is a growing body of knowledge on eccentric resistance training and aquatic plyometric training on muscle function measures alone, no research to date has investigated the effects of a mixed training model. Aquatic plyometrics and overload eccentric training are two different training models which could work synergistically because the shortcomings of one model are the virtues of the other (i.e., plyometrics are not as effective at producing large muscle size and strength gains and eccentric-only training largely lacks the functional SSC component). The purpose of this study was to examine and compare the effects of a combined eccentric …

Language Revitalization: Strategies To Reverse Language Shift, Jessica Jamiel Martin

Undergraduate Honors Capstone Projects

Language shift, the process by which a language loses speakers until it becomes extinct, is occurring in speech communities all over the world. This process is influenced by internal and external political, social, and economic factors unique to each community. As its causes and effects are not uniform, a universal model for reversing language shift does not exist. However, several broad principles can be applied across multiple contexts and situations for successful language revitalization. It is essential for the speech community to be the primary decision maker in any program. A thorough assessment of the community’s current status, challenges, and …

Comparative Metabolism Of Aflatoxin B1 In Two Quail Genera Coturnix Japonica And Callipepla Californica, Sean Moody

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

Avian species are highly susceptible to the hepatotoxic mycotoxin aflatoxin B₁ (AFB₁). Domesticated turkeys are exquisitely sensitive, due to a combination of highly-efficient hepatic cytochrome P450 (CYP)-mediated bioactivation, and to dysfunctional alpha-class glutathione S-transferases (GSTAs) which typically detoxify the bioactivated electrophilic metabolite exo-AFB₁-8,9-epoxide (AFBO). Wild turkeys are relatively resistant to AFB₁ in large part due to expression of functional GSTAs. Quail, a related Galliforme, are slightly less sensitive in vivo to AFB₁, but whether this is related to the hepatic metabolic profiles of these two critical enzymes has not been rigorously evaluated. …

Transfer Effects Of A Multiple-Joint Isokinetic Eccentric Training Intervention To Nontraining-Specific Traditional Muscle Function Measures, Steven Spencer

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

The transfer effects of isokinetic, eccentric-only resistance training programs on non-specific measures of muscle function such as isometric peak force, isokinetic concentric peak force and dynamic constant external resistance 1-repetition maximal strength (DCER 1RM) have been researched extensively in a single joint context, yielding mixed results. However, investigations involving multiple-joint isokinetic eccentric-only training models have been sparse. The purpose of this study was to investigate the transfer effects of a short-term multiple-joint isokinetic eccentric leg press (Eccentron) training program on several measures of lower-body strength and performance. Fifteen participants performed Eccentron training three times/week for four weeks and were evaluated …

Impact Of Fish Oil On Intestinal Permeability, Inflammation, And Performance In Swine, Anthony Fernando Alberto

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Our research examined the effects of fish oil supplementation on intestinal permeability, systemic inflammation and performance in piglets. An lipopolysaccharide (LPS) challenge was done to stimulate the synthesis and release of the cytokines, in an effort to mimic the immune response that piglets would have when facing stress or pathogen challenge. Fish oil increased feed intake but did not affect growth when compared to control. Total fatty acid digestibility increased by 6% when fish oil was included in the diet. Also, we observed a 16% increase on 16-carbon fatty acids digestibility. Fish oil did not affect the plasma …

Development And Validation Of A Basic Ground Skills Assessment For Equine-Assisted Services, Sarah J. Andersen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The equine-assisted services program at Utah State University produced and validated an assessment process used to test equines for suitability for equine-assisted services. Equine-assisted services incorporate the interaction of humans who face mental, physical, emotional, and/or social challenges and equines for therapeutic purposes. Recreational, physical, mental, social, and/or emotional goals are met through various equine-assisted services such as therapies, equine-assisted learning, and horsemanship.

Due to the potential for human injury while interacting with equines, it is important to ensure equines are assessed for safe behavior prior to participation in equine-assisted services. This is why our group developed and tested the …

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 …
