A Novel Item-Allocation Procedure For The Three-Form Planned Missing Data Design, Kyle M. Lang, E. Whitney G. Moore, Elizabeth M. Grandfield

Kinesiology, Health and Sport Studies

We propose a new method of constructing questionnaire forms in the three-form planned missing data design (PMDD). The random item allocation (RIA) procedure that we propose promises to dramatically simplify the process of implementing three-form PMDDs without compromising statistical performance. Our method is a stochastic approximation to the currently recommended approach of deterministically spreading a scale's items across the X-, A-, B-, and C-blocks when allocating the items in a three-form design. Direct empirical support for the performance of our method is only available for scales containing at least 12 items, so we also propose a modified approach for use …

How Exercise Impacts The Brain And Cognition, Cody Larson

Biology and Microbiology Graduate Students Plan B Research Projects

Physical exercise has been shown to impact the brains composition and functionality. The changes that arise in the structure of brain, as result of engaging in physical exercise, give rise to cognitive changes. Structural changes are observed most notably in the prefrontal cortex and hippocampus. These changes are preceded by elevations in cerebral blood flow, and growth factors, resulting increased neuroplasticity and neurogenesis. Frequency, duration, intensity, and type of physical exercise can have differing effects on the brain. Moderate intensity aerobic exercise presents the most profound improvements in memory, and inhibitory control over time.

Energy Compensation With Exercise Is Not Dependent On Dose, H. Michael Hays

Theses and Dissertations--Nutrition and Food Systems

Background: Exercise induced weight loss is often less than expected due to a coordinated set of compensatory mechanisms that serve to maintain energy homeostasis. The extent to which exercise frequency, duration, intensity and exercise energy expenditure (ExEE) influences the compensatory response to an exercise-induced energy deficit (energy compensation) is controversial. Determining how these variables impact energy compensation would help health care providers prescribe exercise with greater probability of creating a sustained negative energy balance and subsequent weight loss.

Methods: 44 Overweight/obese men and women (BMI=25-35kg/m²) aged 18 to 40 years were randomized to perform aerobic exercise 2 or 6 days/week …

The Impact Of Exercise In Spaceflight And Microgravity Environments, William Bybee

Mahurin Honors College Capstone Experience/Thesis Projects

Since mankind’s first spaceflight, a significant barricade in reaching distant planets has been the damaging effects of microgravity upon the human body. Effects range from loss in bone mineral density and severe muscle atrophy to autoimmune disorders. The most effective countermeasure of these effects to date is exercise. Implementation of exercise in microgravity is not an easy task, so various specialized equipment must be utilized to effectively administer it. Even with this equipment, exercise as it is currently used does not entirely prevent body systems from undergoing detrimental changes. New modalities and implementations are currently being investigated that may significantly …

The Role Of Mitochondrial Pyruvate Carrier 1 (Mpc1) In Heart Failure And Its Implications For Cardiac Recovery, Obadiah Issachar Kirk

Mahurin Honors College Capstone Experience/Thesis Projects

Heart failure (HF) is a complex syndrome with high mortality rates around the world. HF also has diverse etiology as many things contribute such as hypertension, obesity, coronary artery disease, inflammation, and cardiac arrhythmias. Studies have shown that unloading of a failing heart with a left ventricular assist device (LVAD) can lead to cardiac recovery in a subpopulation of individuals with advanced HF. RNA-sequencing and protein expression analysis of myocardial tissue from HF patients who underwent the LVAD implant and heart transplant indicated that subpopulation of HF patients who responded to LVAD unloading had significantly lower levels of mitochondrial pyruvate …

Professional Liability Insurance For Athletic Trainers: A Cross Sectional Study Of Athletic Trainers Who Do Per Diem Work, Kameelah J. Belgrave

Honors Undergraduate Theses

Context: Many secondary school athletic trainers (ATs) complete per diem work as a way to supplement their income. Working per diem means the AT provides services to events that are not part of their main employment. Since this type of work is not connected to their main employment, the AT may lack appropriate professional liability insurance (PLI). PLI is a type of insurance that protects healthcare professionals from bearing the entire cost of defending a malpractice claim made by a former or current patient. Anecdotally, many ATs believe that the PLI provided by their main employer covers all health care …

Development Of Rat Head Finite Element Model And Tissue Level Biomechanical Threshold For Traumatic Axonal Injury, Runzhou Zhou

Wayne State University Dissertations

Traumatic brain injury (TBI) is caused by local tissue deformation at the time of trauma, leading to neurological dysfunction. In the United States alone, 2.87 million people sustain a TBI each year, of which one-fifth results in death. Traumatic axonal injury (TAI) is a well-recognized consequence of every fatal head injury and more than 85% of vehicular crash-related blunt head injuries. The most common and important pathologic feature of TBIs are multifocal changes to axons in the white matter produced by rapid head acceleration/deceleration during a traumatic event with consequent local shear/tension on neural tissue and axons contributing to secondary …

Vitamin D3 Supplementation And Stress Fractures In High-Risk Collegiate Athletes - A Pilot Study, Kevin Williams, Christian Askew, Christopher Mazoue, Jeffrey Guy, Toni M. Torres-Mcgehee, J Benjamin Jackson Iii

Faculty Publications

INTRODUCTION: Vitamin D is paramount to bone health and little is known about vitamin D's role in the prevention of stress fractures in high-risk athletes. This study consists of a prospective, cross-sectional analysis accompanied by a retrospective review for control comparison of vitamin D3 supplementation in high-risk athletes. Our hypothesis is that supplemental vitamin D3 treatment will decrease the occurrence of stress fractures in high-risk collegiate athletes. MATERIALS AND METHODS: A total of 118 NCAA Division I athletes were recruited from 6 high-risk collegiate teams. Blood draws in August and February established baseline 25(OH)D levels. Subjects with serum 25(OH)D <30 ng/mL were supplemented with 50,000 IU of vitamin D3/week for 8 weeks. Treated subjects were re-tested to ensure serum 25(OH)D levels rose to sufficient status. All enrolled subjects were monitored for the development of stress fractures. A 5-year retrospective chart review of athletes from the same sports teams was conducted to determine the incidence of any reported stress fractures in the past. RESULTS: Prospective: 112 of the 118 enrolled subjects were tested in August. Sixty-one demonstrated vitamin D sufficiency (40.2 ng/mL ±8.28) and 51 were either insufficient or deficient (22.7 ng/mL ±4.89). Of the 118 enrolled subjects, 104 were tested in February. Fifty-six demonstrated vitamin D sufficiency (40.7 ng/mL ±9.47) and 48 were insufficient or deficient (21.6 ng/mL ±5.87). Two stress fractures were diagnosed amongst our cohort of 118 student athletes (1.69%). Retrospective: 34 stress fractures were diagnosed in 453 subjects from 01/2010-05/2015 (7.51%). Amongst our athletic teams, the cross-country team specifically demonstrated a statistically significant decrease in stress fracture incidence (p<0.05). We also found a statistically significant reduction in stress fracture incidence amongst the current overall cohort compared to our retrospective cohort (p<0.05). CONCLUSION: In our population, almost half of the tested athletes proved to be vitamin D deficient. Hypovitaminosis D was prevalent throughout the winter months compared with the summer. With vitamin D3 supplementation, the stress fracture rate in our overall cohort demonstrated a statistically significant decrease from 7.51% to 1.65% (p=0.009).
