Role Of Altered Gut Microbiota In Tumor Development, Mucus Production And Inflammation In Apc Min/+ Mouse Model, Kamaljeet Kaur

Theses and Dissertations

The microbiome forms an integral part of the gut microenvironment. Once ignored, the topic has gained momentum in research during the past decade, where studies have strongly suggested the association of microbiota with health and a misbalance thereof, to many disease conditions ranging from inflammation and colitis to diabetes, obesity and colon cancer. The Human Microbiome Project (HMP, NIH common fund - 2008) has used a variety of high throughput analyses in order to study gut microbiota in health. The consortium has so far been able to isolate and characterize more than 1,300 reference bacterial strains from the human body. …

The Effects Of External Focus Of Attention Exercise Rehabilitation On Dual Task Walking In Parkinson's Disease, Eric N. Beck

Theses and Dissertations (Comprehensive)

Parkinson’s disease impairs control of well-learned movements, and therefore, individuals with Parkinson’s disease are forced to walk with greater conscious control. This causes difficulties while walking and completing a secondary task simultaneously (dual tasking), in that distractions from conscious control of walking increase the risk of falls and injury. Although, attention-based exercise may be a potential avenue to decrease the demands associated with walking in Parkinson’s disease. For example, an external focus of attention (on manipulated objects) has been found to recruit the networks that are important for walking with little conscious control (automatic control networks). In contrast, an internal …

Upper Extremity Strength And Power Field Tests As Predictors Of Pole Vault Performance In Female Collegiate Athletes, Carmen Schluter

EWU Masters Thesis Collection

"The purpose of this study was to determine if select upper-extremity strength and power field tests, and the test battery, predict pole vault performance in female pole vaulters. There is very little research on female pole vault athletes, specifically non-elite athletes. Field tests previously shown to be predictive of performance in males were examined to determine if they were also predictive for females. Four tests were used (8 lb backwards medicine ball (MB) throw, 3 m seated rope pull, three pull-ups for time, and maximum pull-ups) to determine if pole vault performance (season personal record for each athlete) could be …

The Effects Of Eating Disorders And Menstrual Irregularity On Bone Mineral Density In Sorority Women: A Cross-Sectional Study, Rachel Robertson

Honors Theses

Past research has reported bone loss among women diagnosed with eating disorders as a direct result of estrogen imbalance (Cobb et al., 2003; Gibson et al., 1999; Kim et al., 2012; Zuckerman-Levin et al., 2014). Menstrual irregularity may result from estrogen imbalance, which is characteristic of an eating disorder and ultimately causes bone loss. Past studies have focused on this three-way relationship between eating disorders, menstrual irregularity, and bone mineral density (BMD) specifically in female athletes (Cobb et al., 2003; Gibson, Mitchell, Reeve, & Harries, 1999) but rarely in recreationally trained or sedentary females. Previous research has also focused on …

Glucose-Fructose Likely Improves Gastrointestinal Comfort And Endurance Running Performance Relative To Glucose-Only, P. B. Wilson, S. J, Ingraham

Athletic Performance Research

This study aimed to determine whether glucose-fructose (GF) ingestion, relative to glucose-only, would alter performance, metabolism, gastrointestinal (GI) symptoms, and psychological affect during prolonged running. On two occasions, 20 runners (14 men) completed a 120-min submaximal run followed by a 4-mile time trial (TT). Participants consumed glucose-only (G) or GF (1.2:1 ratio) beverages, which supplied ~1.3 g/min of carbohydrate. Substrate use, blood lactate, psychological affect [Feeling Scale (FS)], and GI distress were measured. Differences between conditions were assessed using magnitude-based inferential statistics.

Describing The Prevalence And Awareness Of Sport-Related Concussion In University Intramural And Club Sport Participants, Makenzie L. Brown

Health, Human Performance and Recreation Undergraduate Honors Theses

Background: Concussion injuries are growing in number among athletes across the nation. The majority of concussion research to date focuses on collegiate and high school athletes. University athletes make up a small percentage of the student body population compared to the large number of students that participate in club and intramural sports. These students participate in the same sports, assume the same risks, and may experience the same adverse effects of concussion, often without appropriate medical oversight.

Purpose: The purpose of this study was to determine if concussion is a problem among intramural and club sport participants, if these participants …

Blockade Of Tgf-Ss Signaling Through The Activin Type Iib Receptor With The Small Molecule, Sgi-1252, Jordan David Fuqua

Theses and Dissertations

Antagonism of the activin receptor signaling pathway represents a promising potential therapy for the muscular dystrophies and other muscle wasting disorders (i.e., cachexia or sarcopenia). Previous research has shown that antagonism of activin signaling promotes muscle growth, attenuates muscle wasting, and restores function in both wild type and diseased animals. Our laboratory has recently developed a novel small molecule (SGI-1252) that inhibits activin downstream (i.e., Smad2/3 phosphorylation) signaling. Purpose: In this study we determined how eight weeks of orally administered SGI-1252 affected TGF-ß signaling, whole body mass, individual limb muscle mass, and muscle fiber cross sectional area (CSA). Methods: Wild-type …

Influence Of Benagene Supplementation In Conjunction With High Intensity Cycling Exercise, Wilson P. Simmons

Honors Theses

High intensity aerobic performance is determined by the body’s maximal ability to match lactate production and clearance rates, defined as the lactate threshold (LaTh). Intensities performed above the LaTh result in accumulation of lactate causing fatigue. In a double-blind experiment, using trained cyclists and triathletes, we investigated skeletal muscle adaptations that occurred following 28-days of Benagene supplementation (oxaloacetate). The testing protocol consisted of an initial cycle test (T1) to measure VO₂max, LaTh, respiratory exchange ratio (RER), power output (PO) and heart rate (HR). Testing began after a 15-min warm-up at 75W, beginning at 100W, increasing 30W each 3-min …

Misrepresentation Of Carbohydrate For Exercise: ‘It Is Time To Bust The Myth Of Physical Inactivity And Obesity: You Cannot Outrun A Bad Diet’, Patrick B. Wilson

Athletic Performance Research

The contention from Malhotra et al1 regarding the unimportance of carbohydrate for exercise is misguided. First, the reference they provide is an editorial2 that should not be viewed as high-quality evidence. Several oft-cited exercise studies showing benefits with high-fat diets simultaneously utilized carbohydrate restoration strategies,3 which involves “carbohydrate loading” after a high-fat diet. Thus, the evidence provided does not contradict the established belief that carbohydrate is an important fuel for endurance exercise. Second, the authors’ use of the term “carbohydrate loading” is misleading in this context. No public health organizations advocate a diet containing carbohydrate in amounts used in “carbohydrate …

Research outputs 2014 to 2021

This study investigated relationships between 10 m sprint acceleration, step kinematics (step length and frequency, contact and flight time), and leg muscle performance (power, stiffness, strength). Twenty-eight field sport athletes completed 10 m sprints that were timed and filmed. Velocity and step kinematics were measured for the 0-5, 5- 10, and 0-10 m intervals to assess acceleration. Leg power was measured via countermovement jumps (CMJ), a five-bound test (5BT), and the reactive strength index (RSI) defined by 40 cm drop jumps. Leg stiffness was measured by bilateral and unilateral hopping. A three-repetition maximum squat determined strength. Pearson’s correlations and stepwise …

The Effect Of Aerobic Exercise Versus Inactivity On Nitric Oxide Concentration And Synthesis In An Elderly Population, Samantha Burton

Theses and Dissertations

CONTEXT: Nitric Oxide (NO) is an endothelial-derived vasoactive molecule that causes an increase in blood flow and oxygen delivery to tissue. A reduction in NO bioavailability has been found to occur in adults over the age of 60 and can be reversed pharmacologically by improving NO synthase (NOS) activity. Reversing these age-related changes with alternative interventions, such as aerobic exercise, has shown some promising results. OBJECTIVE: To quantify blood NO-bioavailability (as measured by blood nitrite levels) in a population of aerobically trained elderly men and compare these data to a group of age-matched, inactive individuals. In addition, we measured the …
