The Meaning Of Physical Activity In The Context Of Health Sciences: A Concept Analysis, Martín G. Farinola

International Journal of Physical Activity and Health

Physical activity has been defined in numerous ways. Thus, this study aimed to conduct a concept analysis of the existing physical activity definitions in the health sciences literature to evaluate its conceptual precision and assess the need for a revised or novel concept better suited for this domain. The concept analysis was accomplished using tools derived from philosophical semantics. The analysis identified six definitions that explicitly state what physical activity is with sufficient clarity to allow for conceptual examination. The findings indicated that these definitions frequently merge the concept of physical activity with its contextual attributes. To address these semantic …

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 …

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 …

Domain-Specific Concussion Knowledge And Reporting In United States Major League Rugby Players, Julie Stamm, Katherine Hunzinger, Owen Sheehy, Christine Baugh

Department of Exercise Science Faculty Papers

Previous research indicates high concussion knowledge is not associated with better concussion reporting, with research examining the relationship between reporting and global concussion knowledge. Concussion knowledge has not yet been investigated in United States Major League Rugby (MLR) players. This study evaluated domain-specific concussion knowledge, concussion history, and reporting behaviors among active MLR players. In a cross-sectional design, 207 MLR athletes (age 26.6 ± 3.4 years) completed a survey assessing concussion history, knowledge, and nondisclosure reasons. While in the MLR, 24% reported an undisclosed concussion, with nondisclosure reasons related to a lack of concussion knowledge, a desire to continue playing, …

Effects Of Menstrual Cycle Phases On Muscular Strength And Ligament Laxity, Nicole Waldo Johnson

2026 Student Academic Showcase

Female participation in sport continues to increase, yet women remain largely underrepresented in research. Due to hormonal differences, additional research is needed to understand how menstrual cycle (MC) phases influence performance and injury risk. Females experience higher incidences of anterior cruciate ligament (ACL) injuries, which may be influenced by hormonal fluctuations. The purpose of this study is to examine how MC phases and changes affect muscular strength and ligament laxity at the knee. Muscular strength and ligament laxity will be tested twice during the MC: once during the early follicular phase (EFP) and the second set are to be collected …

Neuromuscular Function And Balance In Young Adults: Feasibility And Reliability Of Strength And Conditioning Assessments, Riley Fritzsche, Nicole Waldo Johnson, Jessica M. Moon

2026 Student Academic Showcase

Neuromuscular assessments are widely used in exercise science however; the reliability of comprehensive functional testing batteries in healthy young adults remains unclear. Since sex and hormone status may influence performance, this study proposes that neuromuscular outcomes will differ across males, naturally cycling females, and hormonal contraceptive users. This pilot study will evaluate the feasibility and test-retest reliability of a neuromuscular assessment battery in adults aged 18–35 using a repeated-measures design. Participants will complete two identical testing sessions separated by 5–10 days. Assessments will include balance on force plates, handgrip strength, a 5-repetition chair-rise, and the 3-meter Timed Up-and-Go, alongside neuromuscular …

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 …

Psychosocial Mediators Of A Physical Activity And Dietary Intervention In Pregnant Women With Overweight Or Obesity, Meghan Baruth, Sarah Wilcox, Jihong Liu, Rebecca Schlaff

Faculty Publications

Background

Mediation analyses provide insight into both ‘pieces’ of the mediation chain; they allow us to look into the ‘black box’ that is behavior change. They allow researchers to better understand the ‘how’ of an intervention’s effects and/or the ‘why’ behind why an intervention worked or did not work. The lack of publications in pregnant populations highlights the need for additional studies to be conducted and published. The purpose of this study is to examine the psychosocial mediators of physical activity and dietary outcomes in a sample of pregnant women with overweight or obesity participating in the Health in Pregnancy …

Passive heat therapy, through sauna or hot water immersion, can improve cardiometabolic health outcomes. An increasingly popular thermal modality is contrast therapy, during which sauna therapy is interspersed with cold exposure. However, the acute physiological and perceptual responses to contras therapy in  comparison with traditional sauna remains unknown. This study compared the acute inflammatory, physiological, and perceptual responses to contras against heat therapy in predominantly young, healthy individuals

Recurrent Urinary Tract Infections In An Elite Level Diver: A Disablement Model Case Study, Matt O'Sullivan, Dominique M. Stevens, Lindsey E. Eberman

Clinical Practice in Athletic Training

This article presents a case of complicated and recurrent pyelonephritis, an infection of 1 or both kidneys, in an elitelevel diver. Urinary tract infections (UTIs) are among the most common outpatient infections in the United States; most are uncomplicated and resolve without significant mortality or morbidity. However, UTIs have the potential to present significant clinical challenges if the UTI becomes complicated or recurrent. Additionally, recurrent UTIs can carry a significant burden to both the individual patients and the larger healthcare system. The current paper reviews the epidemiological literature surrounding UTIs, the significant impact they have on a patient’s health-related quality …
