Pain And Pace: Investigating Gait Velocity In Individuals With Cancer, Melaina E. Taylor

2026 Honors Symposium

Background: Cancer remains the second leading cause of death worldwide, with incidence rates continuing to rise. Pain, a hallmark symptom of many cancers, is caused by both the progression of disease and treatments. Gait, the way in which someone walks, is now dubbed the “6th vital sign” for its strong relationship with functional status, longevity, and survival. Specifically, gait velocity is a key metric for gait, with previous studies in cancer free adults showing increased pain associated with a decreased gait velocity. The relationship between gait velocity and pain has not yet been explored in individuals with cancer. Purpose: The …

The Impact Of Heavy Resistance Training On Type Ii Muscle Fibers Throughout Female Reproductive Stages, Lily G. Colberg

Scripps Senior Theses

Type II muscle fibers, also known as fast-twitch muscle fibers, are reliant on aerobic glycolysis and are crucial for high-force contractions, mobility, and rapid movements, such as fast reflexes. Heavy resistance training has been found to increase type II muscle fiber concentration in young, middle-aged, and elderly individuals. However, there have been few studies conducted on female-only sample populations. In women, the impact of heavy resistance training on type II muscle fibers is affected by the progressive decline of estrogen that defines the transition throughout the four female reproductive stages: premenopause, perimenopause, late-transition menopause, and postmenopause. Menopausal estrogen depletion causes …

Ultrasound-Derived Liver Composition And Metabolic Flexibility Under Exercise Stress, Rhodes Van Houten

All Master's Theses

Metabolic Associated Fatty Liver Disease (MAFLD) is characterized by abnormal liver fat accumulation in conjunction with metabolic syndromes. MAFLD affects 33% of individuals worldwide, though little is known about how increased liver fat impacts physiological responses to exercise. This study aimed to analyze the relationship between liver composition and metabolic flexibility during a graded exercise test.  Body composition was analyzed via dual-energy X-ray absorptiometry. Liver ultrasound was evaluated for echogenicity, where elevated mean gray volume (MGV) indicates abnormal liver tissue. Rates of fat (FATox) and carbohydrate (CHOox) oxidation (g/min), respiratory exchange ratio (RER), and blood lactate concentrations ([LA^-], …

Combining Haptic Feedback With Electromyography To Study Knee Injury In Stationary Cycling, Christopher Kirby

Honors Theses

Patellofemoral Pain Syndrome (PFPS) is the most prevalent overuse injury in cycling, often linked to altered neuromuscular activation patterns of the quadriceps and hamstrings. While sensory feedback has successfully modified cyclists posture, there is a critical lack of evidence-based interventions targeting the underlying muscle activation imbalances associated with chronic knee pain. This study aimed to develop and validate a novel, real-time biofeedback system that utilizes electromyography (EMG) to trigger vibrotactile cues, aiming to shift muscle onset timing earlier in the pedal stroke to mitigate PFPS-related imbalances. A closed-loop system was engineered by integrating a Delsys EMG system with a SageMotion …

Comparison Of 2000-Meter Row Prediction To Measured Vo2peak During Gxt, Andrew S. Ashley

College of Graduate Studies: Theses & Dissertations

BACKGROUND: Aerobic capacity is essential for the performance of military personnel and first responders. Traditionally, graded exercise tests (GXTs) with metabolic gas analysis have been the criterion-referenced method for assessing aerobic fitness. However, treadmill running and cycle ergometers may not fully reflect the whole-body demands required in tactical environments. Rowing-based assessments and the currently commercially available VO2max prediction formula are widely used across tactical organizations as practical field measures, and most tactical operators are considered inexperienced rowers, which has been minimally examined. PURPOSE: The purpose of this study is to compare measured VO2peak from a rowing GXT with estimated VO2max …

Coordinated Whole-Body Dynamic Pressing And Reaction Inhibition — Impact Of High-Intensity Intermittent Exercise And Dehydration, Modesto A. Lebron

Graduate Studies Theses and Dissertations 2026

Dynamic whole-body pressing movements are an imperative aspect of various sport and occupational settings, requiring motor coordination to kinetically sequence from lower- to upper-extremities. Recently, exercises such as the jammer arm punch press (JPP) have increased in popularity, promoted as an exercise to improve strength and force transfer. While the JPP has observed increased practical utility, its use in research is limited potentially due to difficulties with quantifying exercise intensity. One method to quantify exercise intensity is the assessment of velocity, serving as the basis for velocity-based training.
