Kinesiology Department Chairs’ Perceptions Of Their Training And Preparation, Kason O’Neil

Electronic Theses and Dissertations

Department chairs are responsible for leading academic departments in higher education.  These individuals regularly make important decisions regarding such things as managing faculty and academic programming, overseeing budgets, and supporting student needs. Despite these responsibilities, many people become department chairs without receiving formal leadership training. This study explored how kinesiology department chairs across the United States viewed their preparation for the role and the importance of leadership training. A total of 111 department chairs completed an online survey about their background, previous training, and the importance of training for different administrative responsibilities. The results showed that most chairs had little …

Comparison Of Lower-Extremity Coordination Patterns During Countermovement Jumps Between Dancers And Nondancers, Danielle Joseph

Honors Theses

Jumping is a skill essential to several different sports, including dance. For athletes in jump-dominant sports, jump strategies can vary with differences in task demands while jump performances are similar. The countermovement jump (CMJ) has been utilized to analyze jumps because of their reliable indications of power and neuromuscular function. Methods of describing jump strategies using CMJ, such as force plate metrics, vector coding analysis, and coordination phases, have been used to describe the jumps of athletes in jump dominant sports such as basketball and volleyball. However, less jump strategy research has been done on dancers, especially to describe the …

Assessing The Relationship Between The Degree Of Static And Dynamic Quadricep Angle And Kinetic Asymmetry Index % In Females During The Follicular Phase Of Menstruation, Madeline Grace Poirier

All NMU Master's Theses

The quadriceps angle (q-angle) quantifies lateral pull on the knee. Females have greater static and dynamic q-angles due to anatomical factors including a wider pelvis and more lateral tibial tuberosity, which may influence ACL injury risk. The kinetic asymmetry index (KAI %) measures limb-to-limb differences in ground reaction force (GRF) impulses during dynamic tasks including countermovement jumps (CMJs), with values > 10% linked to injury risk. During the follicular phase of the menstrual cycle, fluctuating hormones increase joint laxity, further heightening biomechanical vulnerability in females.

This cross-sectional study examined the relationship between static and dynamic q-angle and KAI % in active, …

Fear Of Negative Evaluation And Intrinsic Motivation In Resistance-Trained Individuals: A Comparison Of Novice And Experienced Lifters, Karter Bokker

Student Theses and Dissertations

This study examined the relationship between fear of negative evaluation (FNE) and intrinsic motivation in resistance-trained individuals and compared FNE levels between novice and experienced lifters. Twenty-two male participants (n = 8 novices, n = 14 experienced) completed questionnaires assessing FNE and intrinsic motivation. A Pearson correlation and independent-samples t-test were conducted. Results indicated no significant relationship between FNE and intrinsic motivation (r = -.144, p = .523). However, novice lifters reported significantly higher FNE scores than experienced lifters, (t20) = 2.71, p = .014, with a large effect size (d = 1.20). These findings suggest that while FNE may …

Severity Of Deficit In Skeletal Muscle Lipid Metabolism Invokes Unique Adaptive Responses In Dietary Lipid Intake And Absorption, Victoria Datta

Masters Theses

Skeletal muscle plays a central role in whole-body lipid metabolism through mitochondrial and peroxisomal fatty acid oxidation (FAO). When skeletal muscle lipid metabolism is impaired, whole-body adaptations occur to maintain metabolic homeostasis. We hypothesized that limiting skeletal muscle lipid metabolism through mitochondria and/or peroxisomes would trigger adaptive responses to reduce dietary lipid intake and/or absorption with the most robust changes coinciding with deficit severity. Mice were generated with skeletal muscle-specific deletion of 1) carnitine palmitoyltransferase 1b (Cpt1bM-/-) to limit mitochondrial FAO, 2) peroxin 5 (Pex5M-/-) to impair peroxisomal FAO, and 3) both Cpt1b and Pex5 (DKO). Results were compared to …

Working Out Your Self-Image: Strength, Self-Esteem, And Human Flourishing, Kingston K. Christie

Honors Projects

This project integrates empirical research in exercise science with theological anthropology to examine the psychological effects of resistance training and the meaning of strength within a Christian framework of human dignity and flourishing. The empirical component investigated the effects of a four-week progressive resistance training intervention on global self-esteem and physical self-concept among undergraduate university students with moderate-to-low baseline self-esteem. Eleven participants (N = 11; 20.15 ± 1.52 yrs) completed the Rosenberg Self-Esteem Scale (RSES) and Physical Self-Description Questionnaire Short Form (PSDQ-S) before and after the intervention, with muscular strength assessed via submaximal testing across the squat, bench press, deadlift, …

Ankle Dorsiflexion Is A Primary Influence On Single Limb Landing Stability Regardless Of Menstrual Cycle Chase, Olivia Matrulli

Honors Theses

Context: Hormonal fluctuations associated with the menstrual cycle contribute to modifications in joint laxity. Conflicting evidence supports increased ligamentous injury risk and altered postural control in response to these cyclic changes. Objective: To quantify changes in passive joint flexibility and dynamic postural control across the menses and luteal phases of the menstrual cycle. Design: Repeated measures. Setting: Research laboratory. Participants: Thirteen healthy females (20 [1] y, 1.62 [0.06] m, 67.42 [11.75] kg) with a regular menstrual cycle over the last twelve months volunteered. Interventions: Participants performed five static flexibility tests and three single-leg drop landings onto a force plate with …

Slouching Towards Inefficiency? The Cardiometabolic And Cognitive Costs Of Poor Posture, Ava Mae Fitzenrider

Honors Projects

Posture affects all of our lives. It is both static and dynamic, adapting continuously to environmental demands. One postural alteration frequently observed in occupational settings is hyperkyphosis, which can be induced by sitting position. During computer use, individuals commonly adopt a slouched posture, which can exacerbate hyperkyphosis, and contribute to dis-ease within the body. Previous research has demonstrated that such postural deviations can negatively affect pulmonary function, as well as other bodily functions. Despite these findings, the effects of acute hyperkyphosis (“slouching”) on cardiometabolic function and cognition remain largely unexplored. Therefore, the purpose of this study was to examine the …

The Marathon Without Running: Experiencing A Runner's Sensorial Journey, Harin Kim

Masters Theses

The marathon is defined not by motion alone, but by the changing conditions a body moves through—and remains within—over time. Breath, cadence, heat, sound, crowd compression and attention fluctuate, producing phases that structure the race from within. These interior states are difficult to access by spectators from the sidelines, yet they are precisely what shape the runner’s experience.

This thesis begins with a simple but unconventional question: How can an exhibition translate the runner’s physical sensations and emotions into a multidimensional experience for spectators who do not run? Through a sequence of pop-up exhibitions placed along the New York City …

The Effect Of Acute Hypoxia Exposure, With Exercise, On Bone Metabolic Biomarkers, Alyssa Bailly

Health, Exercise, and Sports Sciences ETDs

Hypoxic environments, resulting from decreased atmospheric partial pressure of oxygen, reduce oxygen availability in the blood and tissues, leading to a mismatch between supply and demand. This elicits several physiological adaptations and may influence bone metabolism. Although evidence suggests that hypoxia can modulate bone remodeling through hypoxia-inducible pathways, findings remain mixed, with most data derived from chronic hypoxic exposures in animal and cell culture models. Exercise, an essential stimulus for bone health, may exacerbate hypoxic stress; however, the skeletal response to acute hypoxic exposure combined with exercise remains unclear. We propose that intermittent exercise in hypoxia may increase negative markers …

The purpose of this capstone project was to advance clinical skills by applying the OTTO approach to examine its effect on occupational performance and UE motor function in …

Exploring The Biological Basis For Exercise Neuroprotection In Parkinson’S Disease: A Cross-Sectional Study Of Exercise And Physical Activity On Inflammatory Cytokines And Neurotrophins, Leah Isabelle P. Alegre, Jacob M. Brewer, Adeline Florschutz, Kate E. Hamiltonthompson

UNLV Theses, Dissertations, Professional Papers, and Capstones

Regular exercise and physical therapy are known to increase production of neurotrophins, including brain-derived neurotrophic factor (BDNF), and anti-inflammatory cytokines. These changes combine to theoretically protect and slow the progressive loss of neurons in Parkinson’s disease (PD). The purpose of this study was to examine the effect of exercise and physical activity on various anti-inflammatory and pro-inflammatory cytokines and neurotrophins in people with PD (PwP). This was a cross-sectional design involving PwP (n=37), aged 43-85 years, who participated in two 30-minute bouts of exercise (with brief rest breaks during and pre/post blood draws) separated by a week. Measures collected prior …

Examining Demographic And Contextual Differences In Stress-Related Sport Interference Among U.S. Collegiate Sport Participants, Heather Tran

UNLV Theses, Dissertations, Professional Papers, and Capstones

Collegiate athletes experience a range of stressors that may interfere with sport performance; however less is known about how stress-related sport interference varies across demographic groups and contexts. Guided by the transactional model of stress and coping, this study examined differences in stress-related sport interference by gender, race/ethnicity, and year in school, as well as across situational contexts (training, competition, and life outside of sport). Data were drawn from a secondary dataset of 288 collegiate sport participants who completed the Sport Interference Checklist (SIC). Independent samples t-test and analyses of variance (ANOVA) were used to examined demographic differences, and a …

Effects Of Combined Action Observation, Motor Imagery, And Neuromuscular Electrical Stimulation On Muscle Strength And Size During Short-Term Upper Limb Immobilization, Zahra Pourhatami

Theses - ALL

Short-term limb immobilization induces rapid declines in muscle strength that exceed reductions in muscle size, suggesting a dominant role of neural mechanisms in early functional decline. Interventions capable of simultaneously targeting central neural and peripheral muscular pathways may therefore offer superior protection during disuse, yet such combined approaches remain unexamined in upper limb immobilization models. To investigate the effects of combined action observation with motor imagery (AOMI) and neuromuscular electrical stimulation (NMES) (AOSTIM) on muscle strength, size, and quality during 7 days of upper limb immobilization, we conducted a study in healthy young adults. Forty-three healthy young adults were randomly …

The Role Of Creatine Supplementation On Neuromuscular Function, Mark Petry

Theses - ALL

This study examined the effects of short-term high-dose creatine monohydrate (CrM) supplementation on neuromuscular and corticospinal function in healthy adults. Creatine is widely recognized for its role in enhancing muscular performance and energy availability, yet its short-term effects on neural and neuromuscular outcomes remain unclear. The purpose of this investigation was to determine whether three days of CrM loading would influence maximal voluntary contraction (MVC) peak torque, corticospinal excitability (CSE) measured via transcranial magnetic stimulation (TMS)-induced motor evoked potential (MEP) amplitude, muscle cross-sectional area (CSA) and muscle quality via echo intensity (EI). Nine healthy creatine-naive adults completed a repeated-measures design …

Associations Between Levels Of Physical Activity And Cognitive Health, Gemma Goldenbaum

Honors Theses

The purpose of this study is to examine the relationship between physical activity levels and executive function, specifically focusing on inhibitory control and working memory capacity. Though the benefits of exercise on brain health are well-documented, the extent of cognitive differences between sedentary individuals and elite student-athletes remains misunderstood. Eighty participants (ages 18–35) were categorized via the International Physical Activity Questionnaire (IPAQ) into sedentary, low, and advanced activity tiers. Participants completed computational assessments, including the Operation Span (OSPAN) task for working memory and Go/No-Go tasks to measure response inhibition and implicit associations. Preliminary results indicated significant differences in sedentary behavior, …

Teaching Exercise: A Survey On Educational Aids And Self-Efficacy, Joshua I. Eaton, Lucas Morgan, Matthew Hermes

Honors College Theses

HEPs are an important part of therapeutic treatment because they allow for greater exercise stimulus than can be achieved from supervised exercise alone. 94.7% of physical therapists reported prescribing HEPs to their patients. However, patient adherence to these plans can be as low as 35%. Lack of HEP adherence likely leads to sub-optimal clinical outcomes in physical therapy patients. Self-efficacy is improved in patients by supplementing HEPs with instructional aids, especially in the form of videos instead of pictures or descriptions, because they act as a form of vicarious experience. It is possible that improving self-efficacy through vicarious experience could …

Polydactyl Precursors: Insights Into Early Tetrapod Locomotion From Polydactyl American Alligators, Trevor P. Brewington

All Theses

Several of the earliest tetrapod lineages exhibited polydactyl limbs, with seven or eight digits per limb rather than the typical five or fewer seen in extant lineages. How these digit configurations might have been used during terrestrial locomotion is unclear, given the lack of living models in which their performance can be studied and limited evidence from fossil trackways. However, polydactyly occasionally appears in natural populations of American alligators (Alligator mississippiensis), animals with body plans that broadly resemble those of early tetrapods. To test how polydactyl limbs similar to those of early tetrapods might have functioned on land, …

Exploring Exercise Motivation And Mental Well-Being In College Students, Elaine M. Lindesmith, Anqi Deng Dr

Health, Human Performance and Recreation Undergraduate Honors Theses

This study examined the relationship between physical activity, exercise motivation, and mental well-being among 48 undergraduate students at the University of Arkansas. Guided by Self-Determination Theory, the study used survey data to measure depression, anxiety, physical activity, and open-ended exercise motivation responses. Motivation responses were coded as autonomous or controlled.

Results showed that physical activity was weakly and negatively related to depression and anxiety, but these relationships were not statistically significant. There were also no significant differences in mental health between autonomous and controlled motivation groups, and motivation did not significantly predict mental health outcomes in regression analyses. Overall, the …

Which Energy Expenditure Equation Is Most Accurate In A Field-Based Setting?, Merrill C. Ward

All Graduate Reports and Creative Projects, Fall 2023 to Present

Several energy expenditure prediction equations for walking on varied terrain exist; however, these predictions are often theoretical and have not undergone rigorous field testing for accuracy. Field research on this topic is sparse. The aim of this study was to determine if any existing energy expenditure prediction equations are accurate in a field-based setting with load and gradient being taken into account (i.e., under conditions that are most applicable to day hiking). This was done by directly measuring relative VO₂ (ml/kg/min) of study participants and comparing these direct measurements to the values generated from the existing prediction equations. Fifteen …

The Impact Of High-Cadence Cycling On Overground Running Performance In Recreational Runners, Matthew Ott

Master's Theses

Cycling is a commonly used exercise because it provides a controllable cardiovascular and musculoskeletal demand while imposing relatively low impact on the rider. High-cadence cycling (HCC) has been shown to influence subsequent running performance and gait performance by increasing cadence and reducing work rate when cycling prior to running. However, most of this work has focused on triathletes and older adults. Therefore, the purpose of this study was to examine the acute effects of HCC on subsequent 800 m running performance and spatiotemporal parameters in adult recreational runners. Thirty recreational runners completed two testing sessions. On Day 1, participants performed …

Comparative Biomechanics: Blattodea Antennal Morphology And Physiology, Lucas W. Marsh

All Theses

Equipped with muscle-free antennae, many insects can twist and bend their antennae on demand. We hypothesized that hemolymph circulating through the antennae provides pressure that facilitates twisting and bending and provides a feedback control channel for tactile sensing in insects. To test this hypothesis, we conducted a thorough morphological and physiological analysis of antennae in three Clades of Blattodea. We studied morphology by evaluating the distinguishable features of the body and antenna, as well as the internal structure of the antennal lumen. Then, in a series of experiments on live cockroaches, we measured blood pressure along the antenna. This was …

Applying Motivational Interviewing-Based Health Coaching Within An Existing Exercise Referral Program: A Cost, Implementation, And Effectiveness Analysis, Zachary Joseph Friedman

Graduate Theses and Dissertations

Higher levels of physical activity (PA) are known to be associated with lower rates of chronic disease and better quality of living. However, population-wide deficits in PA continue to demand strategies for supporting PA-related behavior change. Health coaching represents a promising intervention strategy for behavior change, but its effectiveness in generally healthy, non-clinical populations is not clear. The purpose of this project was to evaluate the feasibility, cost, and effectiveness of integrating student-delivered, motivational interviewing (MI)-based health coaching into an existing university-based exercise referral program (ERP). Additionally, this study aimed to use students as health coaches, and to document training …

Exploring The Spectrum Of Anxiety During Concussion Recovery: A Comprehensive Examination Of Symptom-Based Anxiety Disorders, Kori J. Durfee

Graduate Theses and Dissertations

Background: Anxiety is common following a concussion, arising from both psychosocial and physiological changes, and can manifest in diverse ways. Despite its complexity and association with worse outcomes, post-concussion anxiety is often assessed as a single construct. Characterizing anxiety presentations following injury may improve the identification of clinically meaningful symptoms and help inform future targeted interventions that can improve concussion outcomes. Purpose: The primary purpose was to determine if symptom-based anxiety disorders occur in adults with concussion and identify pre- and post-injury predictors associated with these disorders. Additionally, the clinical utility and predictive abilities of symptom-based anxiety disorders and variability …

Lumbopelvic Kinematics And Muscular Co-Contractions In Walking Prior To And Immediately Following A Bout Of Prolonged Standing., Stephanie Cotariu

Graduate Theses and Dissertations

Background: Prolonged standing is a common daily activity in a wide array of occupations, and approximately 44% of sample populations develop low back pain (LBP) during prolonged standing. Prolonged standing-induced LBP developers (“Pain Developers”) are three times more likely to develop clinical LBP and can therefore be considered a pre-clinical LBP population. Changes in typical gait have been observed in LBP patients, and walking has been hypothesized as being protective or preventive against LBP development. However, it is unknown whether Pain Developers exhibit similar kinematic adaptations to chronic LBP patients during common daily activities, such as walking. The exact muscular …

Anterior Cruciate Ligament (Acl) Injuries In Female Athletes: Implications For Prevention And Rehabilitation, Natalie Amm

Honors Theses

Anterior cruciate ligament (ACL) injuries are among the most common lower limb injuries and pose significant physical, psychological, and long-term functional challenges for athletes. Additionally, research has suggested that females are up to eight times more likely to experience an ACL injury than their male counterparts. This increased risk is multifactorial with risks including anatomical structure, neuromuscular control, strength deficits, and hormonal fluctuations. However, the elevated risk of ACL injuries in female athletes may not solely be caused by biological differences, but also due to training programs and sports being designed around male athletes. This pushes us to change the …

Exercise As A Non-Pharmacological Intervention For The Prevention And Delay Of Alzheimer’S Disease And Dementia, Eden Culver

Honors Theses

Alzheimer’s disease (AD) and related dementias are rapidly increasing public health concerns due to aging populations and rising life expectancy. Alzheimer’s disease is characterized by progressive neurodegeneration associated with amyloid-β plaques, tau neurofibrillary tangles, neuroinflammation, oxidative stress, and neuronal loss, leading to impairments in memory, cognition, and daily functioning. Because there is currently no cure for Alzheimer’s disease, identifying effective non-pharmacological prevention strategies is essential. This paper examines the role of physical exercise as a preventive and protective intervention for delaying the onset and progression of Alzheimer’s disease and dementia. Current research demonstrates that exercise supports brain health through several …
