Effects Of Obesity On Thermoregulation And Cardiovascular Function During Exercise In Females, Jon David Adams

Graduate Theses and Dissertations

Previous research has shown that obese individuals are at greater risk for heat illnesses because of impaired thermoregulation. However, laboratory studies investigating cardiovascular and thermoregulatory function in obese individuals are difficult to interpret because of low sample sizes and methodological concerns. The purpose of this study was to determine if there are differences in thermoregulatory and cardiovascular function between obese and non-obese females. Twenty-four females, 13 obese (43.3 ± 4 .3 % fat, 77.2 ± 13.7 kg) and 11 non-obese (27.8 ± 6.0 % fat, 55.7±6.7 kg), cycled for 60 min in a warm environment (~40°C, 30% humidity) at a …

Effects Of Lift Velocity On Muscle Activation During Leg Extension, Stephen C. Glass

Stephen C Glass

Abstract: It is not known if manipulating velocity within a prescribed resistance training mode will improve muscle activation. Muscle activations of the Rectus Femoris (RF), Vastus Lateralis (VL), Vastus Medialis (VM) and Bicep Femoris (BF) were examined during a leg extension exercise at 3 different velocities on 15 subjects (10men, 5 female, Age = 21.5 ± 1.8 yrs, Height = 171.2 ± 12.5 cm, Mass = 75.5 ± 16.3 kg). Trials of 1 set of 10 repetitions at 60% of 1RM, were performed at 15, 30 and 60º/s. Bipolar surface electrodes were placed over the BF, RF, VL, and VM. …

Predictors Of 3pq And Quickboard Performance In Power-Oriented Collegiate Athletes, Brendan Putney

Honors Scholar Theses

The measuring of athletic performance via pre participation experiments has been the norm for a long time from high school sports, all the way to professional athletics. These tests help gauge an athlete's physical growth over the offseason, as well as aid in predicting their potential performance in the future. However, performance may diminish as multiple maximum effort assessments are completed due to fatigue. The purpose of this study was to examine targeted assessments for possible novel qualities as performance predictors. Baseline data was taken from a larger performance enhancement study for analysis. Twenty-six men (age: 25+4 yr; height 1.78+0.07m; …

Active Recovery And Electro-Muscular Stimulation On Delayed Onset Muscle Soreness After Endurance Running: A Randomized Clinical Trial, Amanda J. Gramly, Kitrick C. Rhodes, Andrea F. Smith

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background/Purpose: Current research on strategies to decrease delayed onset muscle soreness (DOMS) has focused on the effects of active and passive recovery on athletic performance across various sports, but there is little evidence regarding these recoveries at reducing DOMS induced by aerobic activities, such as running. In addition, there is limited research regarding the efficacy of recovery using electro-muscular stimulation (EMS). Therefore, the purpose of this study was to investigate the effects of active and EMS recovery in decreasing DOMS. Subjects: Forty-eight healthy subjects (25 males and 23 females) between the ages of 20 and 40 (25.1 ± 2.9) participated. …

The Acute Effect Of Endurance Exercise On Lipoproteins Measured By Nuclear Magnetic Resonance (Nmr) In Healthy Men, Hanaa Adnan Shaheen

UNLV Theses, Dissertations, Professional Papers, and Capstones

Background: Cardiovascular disease (CVD) represents a major cause of death in the United States, with abnormal levels of blood lipids and physical inactivity considered as major modifiable risk factors. The conventional lipid profile has been used to assess for CVD risk by directly measuring the concentrations of blood lipids. However, lipoprotein particle size and number obtained from a novel method, Nuclear Magnetic Resonance (NMR) may also asses for CVD risk with greater sensitivity. Exercise and increased physical activity has been shown to produce favorable effects on blood lipids and consequently reduce CVD risk. To understand this effect, it is important …

Exercise-Induced Neuroprotection In A Hemiparkinsonian 6-Hydroxydopamine Rat Model, Merrill Russen Landers

UNLV Theses, Dissertations, Professional Papers, and Capstones

Outside of finding a cure, one of the preeminent goals of research in Parkinson's disease (PD) is finding a neuroprotective treatment that when applied prior to the onset of the disease will decrease the risk and severity of the subsequent disease. One such treatment that has potential as a neuroprotective agent in PD is exercise. Several studies have found forced exercise to be protective of Parkinson's disease in adult rodent models; however, few of these studies have used a design wherein voluntary exercise was evaluated. Moreover, no study has used a true neuroprotective design in which exercise was applied prior …

Alternative Therapy And Treatment Of Type 2 Diabetes, Carmine R. Grieco

Human Movement Studies & Special Education Theses & Dissertations

The rise in prevalence and incidence of type 2 diabetes mellitus (T2D) in the developing world continues unabated. Current treatment strategies, however, fall short of achieving optimal glycemic control. The aim of project I was to investigate the effect of an acute bout of a yogic breathing exercise on heart rate variability (HRV) in individuals with T2D. Project II was designed to assess the effectiveness of the neurohormone melatonin in lowering short- and long-term glucose levels, lipids and oxidative stress in T2D. Project III investigated the differential effects of two different styles of aerobic exercise on postprandial glycemia, mood and …

Exercise and Nutrition Sciences Faculty Publications

Despite improved outcomes in the past 30 years, less than half of all women diagnosed with epithelial ovarian cancer live five years beyond their diagnosis. Although typically treated as a single disease, epithelial ovarian cancer includes several distinct histological subtypes, such as papillary serous and endometrioid carcinomas. To address whether the morphological differences seen in these carcinomas represent distinct characteristics at the molecular level we analyzed DNA methylation patterns in 11 papillary serous tumors, 9 endometrioid ovarian tumors, 4 normal fallopian tube samples and 6 normal endometrial tissues, plus 8 normal fallopian tube and 4 serous samples from TCGA. For …

Surf Lifeguard Perceptions And Practice Of Cardiopulmonary Resuscitation (Cpr), Kevin Moran, Jonathon Webber

International Journal of Aquatic Research and Education

While the importance of lifeguards in providing immediate and effective basic life support (BLS) in drowning has been well reported, not a lot is known about how lifeguards perceive the relative value of CPR as a lifeguard skill, their training in it, and the likelihood of resuscitation being successful. A self-complete questionnaire was completed by 252 volunteer surf lifeguards at 16 surf beaches in the Greater Auckland,NZ region. Results show that most lifeguards (65%) had received training in the 3 months before the survey, 83% were willing to perform CPR, few (9%) had used CPR in an emergency, and many …

Human Movement Studies & Special Education Faculty Publications

Purpose: The purpose of this study was to investigate the vibrotactile detection thresholds of the plantar cutaneous afferents in subjects with chronic ankle instability compared with healthy control subjects. Methods: Eight adults with chronic ankle instability and eight adults with no ankle sprain history participated. Vibrotactile detection thresholds were assessed using a mechanical stimulus generator system, mounted onto an articulated microscope arm, which delivered sinusoidal vibrotactile inputs to the foot sole at three different sites: head of the first metatarsal, base of the fifth metatarsal, and the heel. Vibrotactile stimulation was delivered at a range of test frequencies that corresponded …

Physical Activity, Sleep Patterns, And Health Outcomes In University Law Enforcement Officers, Nicole C. Koebke

Theses and Dissertations--Kinesiology and Health Promotion

Research indicates that law enforcement officers (LEOs) have a higher prevalence of developing coronary artery disease (CAD) compared to the general population. Sleep deprivation and physical inactivity have been found to be related to many risk factors for CAD. This cross-sectional study examined the health status and the relationship between sleep and physical activity outcomes versus CAD risk factors among 27 University LEOs. The subjects’ health behaviors, and CAD and metabolic syndrome risk factors were described using basic statistics. Accelerometer derived sleep and physical activity outcomes were correlated to measures of health to identify potential relationships. 33% of LEOs were …
