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

What Happens After The Program Ends? Maintenance Of Physical Performance And Resistance Exercise Participation Following Exercise Oncology Interventions, Alexander Matthew Brooks

Theses and Dissertations

BACKGROUND: Cancer survivors frequently experience persistent impairments in physical performance that compromise functional independence, quality of life, and long-term health. While supervised exercise programs meaningfully improve physical performance, there is uncertainty regarding the durability of these benefits and the factors that influence long-term participation after programs end. Although exercise oncology programs typically include both aerobic and resistance exercise (RE), participation in RE tends to decline once supervision ends and remains lower than aerobic exercise over time. Therefore, the overarching aims of this dissertation were to: 1) evaluate the sustainability of physical performance improvements following exercise interventions in cancer survivors; 2) …

Resting-State Functional Connectivity Of Dopaminergic Reward Pathways Across The Adult Lifespan, Julia Cardarelli

Theses and Dissertations

This study investigates the effect of age on three major dopaminergic reward pathways using resting state functional magnetic resonance imaging. Resting state imaging refers to low-frequency brain connectivity in the absence of task demands or directed thought patterns. The pathways included in this thesis are as follows: the nigrostriatal, mesolimbic, and mesocortical pathways. These pathways rely on dopamine and are known for a variety of functions, most notably regulating responses to rewarding and aversive stimuli. This analysis compared the connectivity between key regions of interest, where transmission originates in the midbrain and substantia nigra, and terminates in the orbitofrontal cortex, …

The Effects Of Whole-Body Vibration On Countermovement Jump Kinetics And Performance, Garrett Reese Evans

Theses and Dissertations

PURPOSE: Whole-body vibration (WBV) is reported to be an effective training modality for increasing vertical jump height. However, the underlying mechanisms are unclear because limited studies have examined the effects of WBV on kinetic variables underling jump height. The purpose of this study is to examine the effects of WBV on jump height (JH), modified reactive strength index (RSImod), and eccentric rate of force development (eRFD) during the countermovement jumps (CMJ) in recreationally-active young adults.

METHODS: Fifteen participants (13 male, 2 female, 21.5±1.89yr, 1.78±0.10m, 80.2±15.0kg) completed three randomly-ordered WBV exposures (0s, 30s, or 60s: 35Hz, 2mm amplitude). Three CMJ were …

Sex Differences In Cardiac Autonomic Response To Physical Exertion Following Concussion In Adolescents, Kiersten Isabella Mangold

Theses and Dissertations

Concussions, or mild traumatic brain injuries, are common amongst adolescent populations. Despite the qualifier of “mild”, these injuries can have a lasting impact on quality of life and school function. It has long been suggested that females experience poorer outcomes following concussion compared to their male counterparts, yet much research focuses primarily on male populations. Various theories have been proposed to explain these reported sex differences in concussion outcomes, ranging from socio-cultural differences in symptom reporting to neuroanatomical differences and the influence of sex hormones. Cardiac autonomic function (C-ANS) has emerged as a potential contributing mechanism to post-concussive symptoms. Although …
