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 …

In this study, we investigated the effects of football shoes with different collar heights on ankle biomechanics and dynamic postural stability. Fifteen healthy college football players performed anterior and lateral single-leg jump landings when wearing high collar, elastic collar, or low collar football shoes. The kinematics of lower limbs and ground reaction forces were collected by simultaneously using a stereo-photogrammetric system with markers (Vicon) and a force plate (Kistler). During the anterior single-leg jump landing, a high collar shoe resulted in a significantly smaller ankle dorsiflexion range of motion (ROM), compared to both elastic (p = 0.031, dz = …

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 …

Effects Of Asthma On Lung Function, Aerobic Fitness, And Physical Activity Levels In Young Adults, Trey Deal
Health, Human Performance and Recreation Undergraduate Honors Theses
Background: Asthma is one of the most commonly diagnosed conditions in the United States. Research has shown that one form of asthma, exercise-induced bronchoconstriction, is experienced by the overwhelming majority of individuals with the condition during physical activity, potentially causing fear and avoidance of physical activity in the future. Physical inactivity could have several negative health implications, including lower lung function and aerobic fitness levels. Purpose: The purpose of this study is to compare lung function, aerobic fitness, and physical activity levels between young adults with asthma to those without asthma. The hypothesis is that there will be a statistically …

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 …

Partitioning The Mechanical Cost Of Human Walking: Unveiling Cost Asymmetries For Bionic Technologies, Michael Richard Isaacs
UNLV Theses, Dissertations, Professional Papers, and Capstones
Biomechanics studies over the past 150 years, suggest that animals, including humans, move at speeds that “optimize” their cost of transport. These optimizations can be metabolic, mechanical, or a mixture of the two; however, the consensus on the relationship between metabolic and mechanical cost has been muddied by our current conceptualizations of mechanical cost. Our prior considerations in assessing mechanical cost of transport for animal locomotion often rely upon the exchange of potential and kinetic energy for a rising and falling center of mass that is supported by rigid legs. As a result, our understanding of the mechanical costs associated …
Respiratory And Perceptual Responses To High Intensity Interval Exercise In Obese Adults,

University of Nevada, Las Vegas
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 …

The Effects Of Group Fitness Classes On Self-Efficacy, Katherine Dalton
Graduate Theses and Dissertations
Self-efficacy is one of the largest predictors of behavior, when related to exercise studies have shown that self-efficacy can predict drop-out rates within six months of being an exercise program (Middelkamp, et. al., 2016; Sallis, et. al., 1988). College students have the biggest decline in physical activity when compared to other stages of life (Buckworth, 2001; Grubbs & Carter, 2002). University recreation centers provide group fitness classes for students to promote physical activity. Minimal research has been done to show the impact that group fitness classes has on student life. This study aimed to show the impact of group fitness …
