Comparison Of Effects Of Sleep Fragmentation On Pro-Inflammatory Cytokine Il-1Β Of Male And Female Adult Mice, Manzar Rzayeva

Mahurin Honors College Capstone Experience/Thesis Projects

Sleep plays an essential role throughout the body by affecting the physiological function and regulation of many systems. One of these systems that receives effects as a result of the adequacy of sleep is the immune system. Previous studies have demonstrated effects of sleep fragmentation upon the immune system; however, sexual differences of these effects have not been studied in depth. To analyze these variances amongst the genders, male and female adult mice were subjected to acute sleep fragmentation (SF) for 24 hours in an automated SF cage that includes a bar sweeping across the cage every two minutes. Meanwhile, …

Validation Of A Novel Vo2max Protocol, Griffin Green Apr 2020

Validation Of A Novel Vo2max Protocol, Griffin Green

Masters Theses & Specialist Projects

Though there are several to choose from, the Bruce protocol is the most commonly utilized treadmill protocol when assessing maximal oxygen consumption (VO2max). Originally developed for cardiac patients, the Bruce protocol may not be an appropriate treadmill protocol for young or trained individuals with higher levels of cardiorespiratory fitness. The steep grade used often leads localized muscular fatigue, which may cause participants to end the test prior to reaching their true VO2max. Another popular protocol, the Astrand, also utilizes a steep grade, but the speed remains constant. Similar to the Bruce, the Astrand protocol may not prompt a maximal cardiovascular …


The Impact Of Exercise In Spaceflight And Microgravity Environments, William Bybee Jan 2020

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 Relationship Between The Metabolic Responsiveness To A High-Fat Meal And An Acute Bout Of Moderateintensity Exercise Among Postpartum Women, Apoorva Tadakaluru Apr 2018

The Relationship Between The Metabolic Responsiveness To A High-Fat Meal And An Acute Bout Of Moderateintensity Exercise Among Postpartum Women, Apoorva Tadakaluru

Masters Theses & Specialist Projects

Background: There has been very little research regarding the metabolic health of women during the postpartum period. Metabolic flexibility is the physiological ability to alter substrate oxidation in response to substrate availability and is a good indicator of overall metabolic health. Metabolic flexibility can be assessed by placing metabolic demands on the body and observing metabolic responsiveness- two examples of such metabolic stressors are lipid oxidation rates in response to a high-fat meal and as well as exercise. However, it is unknown whether postpartum women will respond similarly to these two different types of metabolic stressors. This information will allow …


The Validity Of Submaximal Exercise Testing In Obese Women, Gabrielle Ringenberg Jun 2017

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 …

Single Nucleotide Polymorphisms Linked To Essential Hypertension In Kasigau, Kenya, Julia Carol Freeman Dec 2013

Single Nucleotide Polymorphisms Linked To Essential Hypertension In Kasigau, Kenya, Julia Carol Freeman

Masters Theses & Specialist Projects

Hypertension, or high blood pressure (BP), is an ever-growing epidemic in the developing world. Understanding the genetics behind essential hypertension (EH), or hypertension with no known cause, is especially important. In this study, three single nucleotide polymorphisms (SNPs) known to be linked to an increase in susceptibility to EH were quantified from a cohort of Kenyans living in the Kasigau region. The SNPs are located in three genes that are part of the renin angiotensin system, the primary regulatory pathway in humans controlling BP. They include: AGT (rs699), AGTR1 (rs5186), and HSD11β2 (rs5479). Overall, by using a fluorescent-based RT-PCR technique, …


Computational Prediction Of The Agregated Structure Of Denatured Lysozyme, Pongsathorn Chotikasemsri Dec 2009

Computational Prediction Of The Agregated Structure Of Denatured Lysozyme, Pongsathorn Chotikasemsri

Masters Theses & Specialist Projects

Mis-folded proteins and their associated aggregates are a contributing factor in some human diseases. In this study we used the protein lysozyme as a model to define aggregation structures under denaturing conditions. Sasahara et al. (2007), Frare et al. (2009, 2006), and Rubin et al. (2008) observed conditions where heat denatured lysozyme formed fibril structures that were observed to be 8-17 nanometers in diameter under the electron microscope. Even though the crystal structure of lysozyme is known, the denatured form of this protein is still unknown. Therefore, we used Rosetta++ protein folding and blind docking software to create in silico …

Masters Theses & Specialist Projects

The purpose of this study was to examine the effects of muscle fatigue after a treadmill versus cycle ergometer incremental test on postural balance indices and recovery time recreationally trained individuals. The Bruce Treadmill Test and the Incremental Cycle Ergometer test were used to induce fatigue. Each subject (N=16) performed both exercises, but the order of the exercises was randomized. The subjects performed balance measures on a Biodex Balance System via the Dynamic Balance Test at level 5 and indices were recorded as given. Balance was measured a total of nine times (pre-exercise, immediately post, and at 3, 6, 9, …


The Effect Of Varying Cadence In Cycle Ergometry On Submaximal Predictions Of Peak Oxygen Uptake, Zachary Callahan Aug 2006

The Effect Of Varying Cadence In Cycle Ergometry On Submaximal Predictions Of Peak Oxygen Uptake, Zachary Callahan

Masters Theses & Specialist Projects

The purpose of this study was to investigate the effect that varying cadence had on the ability of a submaximal cycle ergometry test to accurately predict peak oxygen uptake (VO2) using the standard YMCA protocol workloads. There has been limited scholarship investigating the effect that varying cadence has on trained cyclists and almost none on untrained participants. For this study twelve moderately healthy participants (age: 20.75 ± 1.87, body fat: 15.8 ± 4.91 %) who did not use cycling as part of their workout regime performed a peak VO2 cycle test and three randomized submaximal tests. The three submaximal tests …

Acute Cardiovascular Response And Perception Of Effort Between The Super Slow And Gold Standard Resistance Training Protocols, Phillip Wickwire Jul 2003

Acute Cardiovascular Response And Perception Of Effort Between The Super Slow And Gold Standard Resistance Training Protocols, Phillip Wickwire

Masters Theses & Specialist Projects

Super Slow training was proposed by Ken Hutchins in a book entitled Super Slow: The Ultimate Exercise Protocol (1992). Since then Super Slow training has been proposed to improve strength more effectively than traditional resistance training and improve cardiovascular measures above aerobic exercise. However, whether this type of training is safe for the older, possibly hypertensive population to which it is being targeted is questionable. To help provide an answer to this question the purpose of this study was to measure blood pressure, heart rate (HR), and ratings of perceived exertion (RPE) while performing the Super Slow resistance training protocol …

The current study compared RPE-Overall, RPE-Legs and RPE-Chest between fit (n=7) and unfit (n=6) males. Subjects completed a graded cycling test and then, in a counterbalanced order, on two separate days cycled for 60min (intensity~90% of the Onset of Blood Lactate Accumulation (OBLA) - determined via gas exchange indices) at 30}1 degrees Wet Bulb Globe Temperature (WBGT) and 18}1 degrees WBGT. Heart rate (HR), rectal temperature (Tree) and overall and differentiated RPE estimations were collected every 5 minutes. Repeated measures analyses of variance …


Regeneration Of Hair Cell Epithelia In The Chick And Salamander, Kenneth Detwiler Dec 1998

Regeneration Of Hair Cell Epithelia In The Chick And Salamander, Kenneth Detwiler

Masters Theses & Specialist Projects

The acousticolateralis sensory system is characterized by a specific receptor cell type called the sensory hair cell and is found in all vertebrates. There are two types of hair cell sensory epithelia based on location: those of the inner ear, such as the organs for hearing and balance, and the lateral line system located within the epidermis. In mammals, including humans, loss or damage of the hair cells of the auditorysystem results in permanent hearing loss. However, this is not the case with birds and amphibians. Amphibians, with a lateral line system, are capable of replacing lost or damaged hair …
