The Impact Of Acute Exercise On Factor Viii In Young E-Cigarette Smokers, Andrew R. Allen

Masters Theses, 2020-current

Abstract

Background: There is a strong association between factor VIII (FVIII) and presence of cardiovascular disease (CVD). Exercise is a known trigger for myocardial infarction, and the majority of ischemic events from physical stress occur due to an occlusive thrombus. FVIII increases acutely with exercise and remains elevated hours after exercise. Furthermore, FVIII is also higher in cigarette smokers, however, it has not been investigated in e-cigarette smokers. The purpose of this study is to identify potential differences in FVIII before exercise, after exercise, and its magnitude of change in e-cigarette users versus non-users.

Swim Instruction For Individuals With Developmental Coordination Disorder, Susan J. Grosse

International Journal of Aquatic Research and Education

Almost every swim teacher has encountered an individual who had difficulty learning to swim, whose movements appeared dissimilar from peers, or who needed to repeat swim course instructional levels many times. That individual might have had difficulty with sport activities, handwriting, and been clumsy in gross and fine motor tasks. Difficulty with coordination and control of movement may suggest a diagnosis of developmental coordination disorder (DCD). Individuals experiencing DCD may feel left out, inadequate, unhappy, frustrated, and embarrassed by his or her ineptness. These feelings may result in an individual withdrawing or refusing to join in and participate in physical …

Mechanisms Of Statin Effects On Muscle And Neuronal Proteostasis, Daniel Yu

University Scholar Projects

Statins are widely prescribed and used chronically, but we know little about the effects on long-term protein homeostasis during stress and aging. Our aim was to quantify the effect of statins on stress-induced protein damage. We administered atorvastatin in a dose-response curve in Caenorhabditis elegans under naïve control conditions and in conditions of hypertonic and heat stress known to induce muscle damage measurable as countable puncta in a polyglutamine aggregation model of damage. We observed that there is significant polyglutamine aggregation variability among worms at baseline and thus further study requires within experiment baseline controls, per worm. Our results are …

The Relationship Between Sport Commitment With Off-Season Training Time And Previous In-Season Playing Time In College-Aged Soccer Players 2020., Luke Zuber

Master's Theses

Sport commitment is defined as “…the desire and resolve to continue sport participation” (Scanlan, Carpenter, Schmidt, Simons, & Keeler, 1993, p. 6). Since the first definition, the concept has been further refined to reflect a more multidimensional paradigm. Overall, sport commitment is thought to be comprised of the dimensions of enthusiastic commitment and constrained commitment (Scanlan, Chow, Sousa, Scanlan, & Knifsend, 2016). Those constructs can be broken down further to 12 subconstructs that are represented in the Sport Commitment – 2 (SC; Scanlan, Chow, Sousa, Scanlan, & Knifsend, 2016), in order to evaluate the source and level of an individual’s …

The Effect Of Attentional Focus Instructions On Single Leg Balance Performance 2020., Cory Monahan

Master's Theses

Balance and postural control exercises are often a part of exercise programs. During exercise programs, movement practitioners can provide instructions to facilitate performance and learning. Instructions can be used to direct attentional focus, which has been found to affect the performance and learning of motor skills, including balance and postural control tasks. However, no known studies to date have investigated the effect of both internal and external attentional focus instructions on static single leg balance performance. The purpose of this study was to investigate the effect of attentional focus instructions on static single leg balance performance as reflected by the …

Development And Clinical Application Of A Novel Left Ventricular Diastolic Stress Test, Thomas Jake Samuel

Kinesiology Dissertations - Archive

Cardiology has long focused on the hearts ability to generate forward pressure and ejection of blood from the left ventricle to supply the systemic circulation with oxygen and nutrients. The ability and capacity of the left ventricle to fill with blood prior to systolic ejection is equally important and, until recently, has been largely under studied. The coordination of passive elastic recoil and active relaxation allows the left ventricle to fill with blood in early diastole through generation of the transmitral pressure gradient. Therefore, dysregulation of the molecular and cellular mechanisms governing these two processes could lead to diastolic dysfunction. …

The Effects Of Knee Joint Loading On Dynamic Tasks In Individuals Several Years Post-Acl Reconstruction, Meredith Decker

Kinesiology Dissertations - Archive

Joint loading of the lower extremity is studied to identify risk factors for anterior cruciate ligament (ACL) injuries and to determine limb asymmetries. Asymmetrical loading in the lower extremity during ACL reconstruction (ACLR) rehabilitation and at the time of return to sport or activity will cause compensations during functional movements, which can lead to unwanted joint re-injury or long-term joint damage. Re-injury and/or development and progression of knee osteoarthritis (OA) is prevalent after ACLR; therefore, joint loading measurements at extended time points from reconstruction and after return to play may help to identify how asymmetrical loading and compensatory movement strategies …

Effects Of Pre-Workout Caffeine Supplementation On Post-Exercise Hypotension, Shelby L. Gibbs

Electronic Theses and Dissertations

Post-exercise hypotension (PEH) is believed to play a major role in the antihypertensive health benefits of exercise. While it has been shown that resistance exercise is effective at eliciting PEH, commonly consumed sports supplements may attenuate or completely eliminate that response. Caffeine, a popular stimulant, is often consumed prior to exercise. Therefore, the purpose of this study was to investigate the effects of pre-workout caffeine supplementation on the post-exercise hypotensive response in adults with above normal blood pressure. Participants (n = 5) were recreationally resistance trained men and women who consumed placebo or caffeine (3 mg/kg bodyweight) 45-minutes prior to …

Cerebrovascular Function In Adults With Depression, Rauchelle Richey

Kinesiology Theses - Archive

Cerebral vasodilatory responsiveness is blunted in older adults (~45-70 yrs) with depressive disorders and thought to contribute to the link between depressive symptomology and increased risk for neurocognitive (e.g., dementia) and cerebral vascular (e.g., stroke) diseases. In young adults with major depressive disorder (MDD), peripheral vascular endothelial dysfunction is evident; however, to date, limited investigations have examined cerebral vasodilatory function in young healthy adults with MDD. We tested the hypothesis that cerebral vasodilatory responsiveness to a hypercapnic stimulus would be blunted in healthy young adults with MDD compared to healthy non-depressed adults (HA). Fourteen HA (22 ± 3yrs) and 14 …

The Role Of Protein Degradation In Cancer Cachexia In Female Tumor Bearing Mice, Noah Thomas

Graduate Theses and Dissertations

Background: Cancer is a leading cause of death in the world in which half of the people affected by this disease die from its effects. Cancer-cachexia is a syndrome associated with the significant loss of skeletal muscle mass and function, which cannot be fully reversed by nutritional intervention alone and in turn, impairs the host. Cancer-cachexia affects 50-80% of cancer patients and is a primary cause of death accounting for 20-40% of cancer related deaths. Efforts to reverse the effects of cancer-related cachexia have been largely unsuccessful and have primarily focused on the late stages of CC. Methods: Lewis Lung …

Utilizing Breathing Techniques To Maximize Training Performance, Peyton Cater

UNLV Theses, Dissertations, Professional Papers, and Capstones

Anaerobic exercise causes metabolic acidosis to occur in the muscle, which is unfavorable for sustaining high intensity activity, as fatigue starts to set in. In order to compensate for the onset of fatigue produced by an acidic environment, respiratory alkalosis, induced by hyperventilation, can be performed to mitigate these effects. In contrast, research has shown that slowing down the breath rate, such as a two second inhale and three second exhale, has led to an increase in performance outcomes. Purpose: To investigate power output and the physiological responses after implementation of different breathing techniques during the recovery periods of intermittent …

Respiratory And Perceptual Responses To High Intensity Interval Exercise In Obese Adults, Nicholas Andrew Ross

UNLV Theses, Dissertations, Professional Papers, and Capstones

Purpose: Obese adults experience low lung volume breathing at rest and during exercise, which provokes ventilatory constraints and dyspnea on exertion. High-intensity interval exercise (HIIE) has emerged as an alternative to continuous exercise (CE); however, the effects of HIIE on lung volumes, ventilatory constraints and dyspnea on exertion have not been studied in obese adults and thus tolerability of HIIE remains unknown. Therefore, the purpose of this study was to examine the differences in respiratory and perceptual responses during HIIE versus CE in obese adults when compared with nonobese adults. Methodology: Ten healthy, nonobese (24.1 ± 6.2 yr., BMI: 23 …
