The Impact Of Exercise In Spaceflight And Microgravity Environments, William Bybee
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
The Role Of Mitochondrial Pyruvate Carrier 1 (Mpc1) In Heart Failure And Its Implications For Cardiac Recovery, Obadiah Issachar Kirk

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 …
Modifiable Factors That Influence Infant Motor Development At 4 Months And 12 Months Of Age, Lauren Miller
Modifiable Factors That Influence Infant Motor Development At 4 Months And 12 Months Of Age, Lauren Miller
Mahurin Honors College Capstone Experience/Thesis Projects
INTRODUCTION: The choices a mother makes during pregnancy (diet and exercise) and postpartum (environmental stimuli, sleeping situation, feeding practices) could influence a child’s motor skills immediately after birth and into childhood. The objective of this experiment is twofold: 1) to determine factors that may influence infant motor development scores at 4 and 12 months of age, and 2) to determine whether infant motor scores at 4 months of age predict infant motor scores at 12 months of age. METHODS: Infant motor development was assessed by a pediatric physical therapist using the Alberta Infant Motor Scale (4 months) and the Peabody …
The Validity Of Submaximal Exercise Testing In Obese Women, Gabrielle Ringenberg
The Validity Of Submaximal Exercise Testing In Obese Women, Gabrielle Ringenberg
Mahurin Honors College Capstone Experience/Thesis Projects
Background: Submaximal exercise tests use heart rate responses to low-to-moderate intensity activity in order to predict cardiorespiratory fitness (VO2max). Currently used tests may be inappropriate for obese populations as obese women have altered heart rate responses to exercise. The purpose of this project is to test the validity of the Modified Bruce Protocol submaximal treadmill test in obese women. Methods: Normal-weight (NWG) and obese women (OBG) completed the Modified Bruce submaximal treadmill test (to predict VO2max using previously validated equations) and a maximal graded exercise test on a treadmill using the Standard Bruce Protocol (to obtain an …
Assessment Of Endpoint Criteria And Perceived Barriers During Maximal Cardiorespiratory Testing Among Pregnant Women, Caitlin Hesse
Assessment Of Endpoint Criteria And Perceived Barriers During Maximal Cardiorespiratory Testing Among Pregnant Women, Caitlin Hesse
Mahurin Honors College Capstone Experience/Thesis Projects
PURPOSE: Plateau in oxygen consumption (VO2) is the primary indicator for determining if an individual has reached their true maximal aerobic capacity (Howley et al., 1995). Although age and gender-specific secondary criteria (i.e. additional criteria that can be used to identify one’s attainment of maximal effort) have been developed for the healthy population, no secondary criteria have been established for pregnant women (Edvarsen et al., 2014). The primary purpose of this study was to analyze secondary endpoint criteria during VO2max testing among pregnant women during the 2nd trimester. A secondary purpose was to identify emotional and physical …
Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd
Exercise To The Rescue: An Analysis Of Altered Metabolic Gene Regulation Post-Exercise In Lean And Obese Individuals, Brandon Mudd
Mahurin Honors College Capstone Experience/Thesis Projects
The skeletal muscle of obese individuals exhibits a depressed ability to metabolize fats. Exercise training is thought to rescue this dampened ability to metabolize fats; mediated by a coordinated increase in the expression of a network of genes that regulate metabolism and fuel utilization. The purpose of this study is to determine the exercise-induced regulation of metabolically important genes in lean and obese individuals. Muscle biopsies (one pre-exercise/baseline and one immediately post-exercise) were obtained from 4 lean (BF% 24.4 ± 5.5; 23.5 yrs ± 1.9) and 13 obese (BF% 39.7 ± 2.4; 26.1 yrs ± 2.3), age-matched, relatively young subjects, …
An Assessment Of Scholastic Basketball Programs: Administration, Facilities, And Support, Leah Cannady
An Assessment Of Scholastic Basketball Programs: Administration, Facilities, And Support, Leah Cannady
Mahurin Honors College Capstone Experience/Thesis Projects
The main purpose of this study was to validate the survey insturement created to evaluate various aspects of scholastic basketball programs—including but not limited to administration, facilities, and support. All boys and girls head basketball coaches in South Dakota were administered an electronic survey created for the study. To incentivize participation, respondents could choose to be entered to win a monetary donation of $250 to their basketball program. Descriptive statstics were used to summarize respondent demographics and other statistical measures were used to indicate reliability and validity of the survey instrument. Cronbach’s alpha was calculated at .711 and Pearson’s correlation …
Motor Control: Theory And Practical Application For The Youth Basketball Coach, Lucas R. Deckard
Motor Control: Theory And Practical Application For The Youth Basketball Coach, Lucas R. Deckard
Mahurin Honors College Capstone Experience/Thesis Projects
BACKGROUND: Motor control, learning, and development need to be considered by any coach working with youth athletes. When coaches fail to consider these areas, they may be more likely to create practice plans, which omit the innate physiological and psychological differences between youth and adult participants, lessen the development of sport-specific skills, and may create less enjoyable sporting experiences for young players. PURPOSE: The aims of this literature review were to explore recent scientific literature linking motor behavior/development to application in youth basketball, identify major themes, and summarize these concepts in a manner useful to coaches in this environment. METHODS: …
Intergenerational Service-Learning With Exercise Science Students, Mckinze R. Vowels
Intergenerational Service-Learning With Exercise Science Students, Mckinze R. Vowels
Mahurin Honors College Capstone Experience/Thesis Projects
Exercise science professionals often work with older adults to help maintain function and independence. Ageism may begin during undergraduate training, as most have not interacted with older adults. Intergenerational service-learning (ISL) may be a useful pedagogy to facilitate interactions with older adults. PURPOSE: To determine if exercise science students’ knowledge of older adults and ageism are significantly improved by incorporating ISL into an exercise science course. METHODS: Students (n =10) enrolled in Exercise and Aging and from two additional exercise science courses (n = 17) completed pre and post assessments of attitudes towards and knowledge of older adults. Students implemented …
