EWU Masters Thesis Collection
"Mental toughness is commonly associated with successful performance in the realm of athletics. However, despite the prevalence of its usage, the concept remains somewhat ambiguous in its definition and practical application. The purpose of this study was to determine the relationship between mental toughness and running performance amongst collegiate distance runners, a population that has yet to be the center of a mental toughness investigation. Of additional interest was to determine how a coach's servant leadership attributes interacts with athletes' mental toughness. Participants (n = 334) were males and females from 64 collegiate track teams from all divisions of the …

Vitamin D Status, Adiposity, And Athletic Performance Measures In College-Aged Students, Laura Forney
LSU Master's Theses
Research suggests that elevated serum concentrations of 25-hydroxyvitamin D (25OHD) are associated with slowing the development of many age-related chronic diseases. Recent reports also show a positive relationship between 25OHD and muscle synthesis, strength, power and decreased body fat in elderly individuals. However, these findings have not been consistently reported in younger, healthy populations. PURPOSE: To investigate the relationship between 25OHD levels, body composition, measures of aerobic fitness and muscular strength and power in a young, physically active population. METHODS: Thirty-nine active subjects (20 males, 19 females; 23 ± 0.7 years old) reported to the lab six times for testing. …

Electronic Theses and Dissertations
In recent years physical inactivity among students has become a matter of great concern. Nearly 65% of students do not meet the daily recommended level of physical activity, which is 60 minutes or more of moderate to vigorous physical activity each day, with 50% of that time being spent in moderate to vigorous levels of activity (CDC, 2010b). As a result, the 21st century has shown to be a time of many health problems such as, obesity, diabetes, and heart disease. In fact, nearly one third of all children are considered obese or overweight (Slawta & DeNeui, …

Discrimination And Aggregative Patterns Among And Between Populations Of Entamoeba Spp., Katelyn M. Higgins
Honors Senior Capstones and Theses
Kin recognition facilitates the evolution of cooperation in animals, but its relevance in microorganisms and their behavior toward relatives remains unclear. The Entamoeba lineage constitutes an ideal model to determine the behavioral and signaling cues needed for aggregative preference. Chemical cues have been reported for E. histolytica but not E. dispar, suggesting cell-communication between con-specifics and behavioral differences with relevance for disease. Entamoeba varieties have been reported as ‘morphologically undistinguishable’. Two strains of E. invadens have been isolated from different hosts (VK-1: NS - Varanus komodoensis and IP1- serpentes) but were classified within the same ‘species’. Trophozoites …

The Effects Of Whole Body Vibration On Dorsiflexion In Chronic Ankle Instability, Lesley Abigail Thalman
Theses and Dissertations
BACKGROUND: Whole body vibration (WBV) platforms are currently used as adjunctive training devices for exercise programs, and have been shown to facilitate flexibility. One of the biggest contributing factors to chronic ankle instability (CAI) is the lack of dorsiflexion after lateral ankle sprains and WBV may be an effective way to increase range of motion in this population. PURPOSE: Determine if WBV done concurrently with static stretching (SS) is more effective then SS alone in improving dorsiflexion ROM in subjects with CAI. METHODS: Subjects were divided into 3 groups (control, static stretch, and static stretch and vibrate). Subjects stretched 4 …

Skeletal Muscle Function, Morphology, And Biochemistry In Ts65dn Mice: A Model Of Down Syndrome, Patrick Michael Cowley
Exercise Science - Dissertations
A common clinical observation of persons with Down syndrome at all developmental stages is hypotonia and generalized muscle weakness. The cause of muscle weakness in Down syndrome is not known and there is an immediate need to establish an acceptable animal model to explore the muscle dysfunction that is widely reported in the human population. Using a combination of functional, histological, and biochemical analyses this dissertation provides the initial characterization of skeletal muscle from the Ts65Dn mouse, a model of Down syndrome. The experiments revealed that Ts65Dn muscle over-expresses SOD1 protein but this did not lead to oxidative stress. Ts65Dn …

Computational Approaches To Understand Phenotypic Structure And Constitutive Mechanics Relationships Of Single Cells, Scott Wood
All Dissertations
The goal of this work is to better understand the relationship between the structure and function of biological cells by simulating their nonlinear mechanical behavior under static and dynamic loading using image structure-based finite element modeling (FEM). Vascular smooth muscle cells (VSMCs) are chosen for this study due to the strong correlation of the geometric arrangement of their structural components on their mechanical behavior and the implications of that behavior on diseases such as atherosclerosis.
VSMCs are modeled here using a linear elastic material model together with truss elements, which simulate the cytoskeletal fiber network that provides the cells with …
