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 …

Can Kinematics Specify Tool Use Affordances?, Tyler Duffrin

All Dissertations

Object properties such as length, shape, and heaviness, as well as affordance-based properties such as strike-with-ability and poke-with-ability, can be perceived via dynamic touch as functions of inertia tensor invariants. The primary question addressed here was whether people can perceive these same power and precision properties for purely virtual objects, which lack dynamic physical forces. The Kinematic Specification of Dynamics (KSD) principle asserts that missing dynamics are lawfully specified by kinematic (visual) motion patterns, such that kinematic information alone may support successful interactions with virtual objects. In three experiments, we investigated (1) whether virtual reality (VR) users could calibrate to …

Examining Pain Catastrophizing, Mental Toughness, Self-Efficacy, And Perceived Pain In The Performance Of Female Athletes During Their Menstrual Cycle, Carissa R. Martinez

Electronic Theses and Dissertations

Pain is a universal unpleasant or negative experience influenced by physiological, psychological, and environmental factors. Disruption in the neural pathways of pain can affect athletic performance and lead to injury risks. Both negative attributes, such as stress, anxiety, and depression, and positive attributes, such as mental toughness and self-efficacy, contribute to pain perception and catastrophic thinking. The menstrual cycle also plays a critical role in pain catastrophizing, as hormonal fluctuations across different phases may hinder pain perception and performance in female athletes. However, research lacks the inclusion of how these factors impact female athletes. Using a non-experimental quantitative analysis, this …

Associations Between Progesterone-Based Hormone Replacement Therapy Use And Cardiometabolic Risk Factors In Menopausal Women Using All Of Us Data, Jabeth Azpeitia Aranda

Theses and Dissertations

PURPOSE: Hormone replacement therapy (HRT) is often treated as a single exposure, although progesterone and medroxyprogesterone acetate (MPA) may have different cardiometabolic associations. This study examined associations of progestogen type, dose, and recorded duration with cardiometabolic outcomes among postmenopausal women. This retrospective longitudinal analysis included 3,363 non-Hispanic White postmenopausal women from the All of Us Research Program classified as non-HRT controls; oral MPA 2.5, 5, or 10 mg; or oral progesterone 100 or 200 mg. ANCOVA models adjusted for baseline outcome values, age, BMI, waist circumference, medication duration, and blood-pressure-, lipid-, and glucose-lowering medication use, with Bonferroni correction for pairwise …

Physiological, Cognitive, Behavioral, And Perceptual Contributors To Falls Risk Across Middle And Older Adulthood, Jacquelyn Moxey

Rehabilitation Sciences Theses & Dissertations

Falls are multifactorial events influenced by physiological, cognitive, behavioral, and perceptual factors. Although falls prevention research has traditionally focused on older adults and objectively measured physical impairments, less is known about how cognitive performance, physical activity, and perceptions of ability collectively contribute to falls risk vulnerability across middle and older adulthood. This dissertation examined these relationships through three complementary studies.

Study 1 examined associations between cognitive screening performance and physiological falls risk in 315 community-dwelling older adults. Lower global cognitive performance was associated with greater physiological falls risk. Performance on items reflecting attention and visuospatial/executive function demonstrated the strongest domain-level …

Building Bridges: Connecting Biomechanics And Lived Experience In Bertolotti's Syndrome, Andrea Morgan Muffly

Rehabilitation Sciences Theses & Dissertations

Bertolotti’s Syndrome (BSy), characterized by the presence of a lumbosacral transitional vertebra (LSTV), represents a complex clinical entity that affects not only the physical health of the individual, but the quality of their daily life. Prior research on BSy focused on epidemiology, not lived experience, revealing inconsistencies in diagnostic inconsistencies of LSTV morphology. A three-tiered diagnostic system is proposed to streamline the reporting of LSTV subtypes. We examined how BSy is diagnosed, its symptoms, presentation, and how this impacts individuals’ ability to participate in activities of daily living (ADLs) and instrumental activities of daily living (IADLs). We conducted a multi …

Menopausal Symptoms, Psychosocial Factors, And Physical Activity Among Physically Active Midlife Females, Ella Onsoriasl

Exercise Science Theses & Dissertations

Menopausal symptoms are common during midlife and may be associated with females' physical activity (PA) participation, yet how these symptoms relate to PA levels, perceived confidence and enjoyment, and psychosocial resources such as social support (SS), exercise identity, and quality of life (QOL) remains unclear. The purpose of this study was to examine how menopausal symptom severity relates to PA levels, perceived confidence and enjoyment during PA, and psychosocial factors, including SS, exercise identity, and QOL. This cross-sectional study surveyed 151 midlife females aged 40 to 60 who reported engaging in intentional PA at least once per week. Participants completed …

Effects Of Beverage Color During Mouth Rinsing On Measures Of Muscular Endurance, Muscular Strength, And Exercise Perceptions During Isometric Handgrip Testing, Sydney Andrews

Exercise Science Theses & Dissertations

Previous research has shown that color can influence psychological responses, physiological responses, and exercise performance. These effects have been previously attributed to learned associations or expectations which may influence exercise-related outcomes. This study aimed to investigate whether beverage color influences muscular performance during intermittent isometric handgrip exercise. This randomized, single-blind, deceptive crossover study consisted of 34 physically active adults (21.9±3.1 years) who completed a handgrip endurance test under three conditions: red beverage rinse, clear beverage rinse, and no-rinse. Participants were informed that the study would examine the effects of mouth rinsing two commercially available carbohydrate containing sport drinks on muscular …

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, …

Identifying Muscle Health Deficits Among Older Adults With And Without Cognitive Impairment, Ray Guerreros Urbina

Graduate Theses and Dissertations

Age-related declines in skeletal muscle health (SMH) and cognitive function are major contributors to disability, loss of independence, and reduced quality of life among older adults. Emerging evidence suggests that skeletal muscle and cognitive health may be interconnected through shared physiological mechanisms; however, the relationships between specific aspects of SMH and cognitive performance remain unclear. Therefore, the purpose of this study was to examine the relationships between SMH and cognitive performance among older adults and to determine whether SMH differs between cognitively healthy and cognitively impaired individuals after accounting for age and physical activity. A cross-sectional analysis was conducted using …

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 …

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 …

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 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 …

Harnessing Mechanobiology Of Resident Stem Cells To Refine Cell Based Therapeutics, Dakota R. Kamm

WUSM Theses and Dissertations – All Programs

Mesenchymal stem cells (MSCs) are resident cells residing with many adult tissues such as adipose tissue and bone marrow that have the potency for multiple lineage differentiation as well as the capacity to secrete a litany of beneficial factors to maintain homeostasis and promote tissue repair. Since 1995, MSCs have been used therapeutically to treat a variety of conditions from osteoarthritis to heart disease to muscle pathologies. Great leaps have been made in improving MSC-based therapies through optimization of culture methods and select enrichment of cellular subpopulations. More recently, the physical microenvironment of tissue in vivo and culture conditions in …

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 …

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 …

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 …
