The Effects Of Injury On Running Status And Gait Biomechanics, Kristyne Wiegand

UNLV Theses, Dissertations, Professional Papers, and Capstones

Over the past several decades, endurance running has grown steadily as a popular form of physical activity. Running is easily accessible, does not require expensive equipment, and can be performed without specific skill training. Individuals who run also experience health benefits like increased cardiovascular health and reduced risk of all-cause morbidity. Despite these benefits, running is also associated with high rates of musculoskeletal injury. Although researchers have attempted to identify injury risks and mitigate the incidence of running injury, there is still no consensus as to why runners become injured. Research has also attempted to identify biomechanical movement patterns that …

Triglyceride Metabolism Following Oral Fat Tolerance Tests Of Varying Fat Content In Adults, Nathaniel Glen Bodell

UNLV Theses, Dissertations, Professional Papers, and Capstones

Introduction: Investigations of lipid metabolism commonly utilize an oral fat tolerance test (OFTT) to elicit a dramatic increase in serum triglycerides (TG). Although this is common practice there does not currently exist an agreed upon formula for an OFTT. Nor has there been in investigation as to the reliability among commonly used OFTT. Furthermore, the effects of sex and activity level are mixed among the literature. The purpose of this investigation is to discover an ideal OFTT for research and clinical purposes, evaluate the effects of activity and sex on TG metabolism, and to test each OFTT concentration for reliability. …

Arterial Stiffness During Whole-Body Passive Heat Stress In Healthy Older Adults, Zachary J. Schlader, Yoshiyuki Okada, Stuart A. Best, Qi Fu, Craig G. Crandall

Kinesiology and Health Promotion Faculty Publications

We tested the hypothesis that whole‐body passive heat stress reduces arterial stiffness in older adults. At preheat stress (baseline) and when core temperature was elevated by 0.6 ± 0.2°C (mild) and 1.2 ± 0.3°C (moderate), arterial stiffness was measured in eight healthy younger (26 ± 5 years) and eight healthy older (70 ± 4 years) adults in the supine position. Arterial stiffness was estimated from carotid‐to‐femoral pulse wave velocity (cfPWV, applanation tonometry). cfPWV was higher at baseline in older adults (8.8 ± 2.3 m/sec vs. 5.6 ± 0.9 m/sec, P < 0.01) and this difference was maintained throughout passive heat stress (P < 0.01). cfPWV did not change (P ≥ 0.49) with passive heat stress in either …

The Correlation Between Physical Activity And Grade Point Average, Asia Mccoy

Honors Theses

The correlation between grade point average (GPA) and physical activity has typically been researched in adolescents, but not a lot of research has focused on traditional college students. Previous research in adolescents has shown mixed outcomes, but there is still evidence that a positive correlation exists between physical activity and GPA. It is also believed that adolescents who are physically active tend to have better academic outcomes than their non-active counterparts as they mature. The primary purpose of our study was to examine the correlation between GPA and physical activity in students attending the College of Education and Human Sciences …

The Effects Of A 10-Week Judo Program On Cortisol And Stress In Children With Autism Spectrum Disorder, Justine Renziehausen

Electronic Theses and Dissertations

Children diagnosed with Autism Spectrum Disorder (ASD) often have increased levels of stress, leading to dysregulated production of cortisol. Elevated levels of cortisol have numerous known adverse health consequences, and therefore, interventions should be established to help attenuate cortisol production. As judo combines physical activity and mindfulness practice, it may aid in stress reduction and decreased levels of cortisol. Purpose: To examine the effects of a 10-week judo program on stress reactions and salivary cortisol levels in youth with ASD. Methods: 20 children with ASD participated in the 10-week judo program. Changes in acute (before and after one judo session) …

Recommendations For Measurement And Management Of An Elite Athlete, William Sands, Marco Cardinale, Jeni Mcneal, Steven Murray, Christopher Sole, Jacob Reed, Nikos Apostolopoulos, Michael Stone

Faculty Work

Athletes who merit the title elite' are rare and differ both quantitatively and qualitatively from athletes of lower qualifications. Serving and studying elite athletes may demand non-traditional approaches. Research involving elite athletes suffers because of the typical nomothetic requirements for large sample sizes and other statistical assumptions that do not apply to this population. Ideographic research uses single-athlete study designs, trend analyses, and statistical process control. Single-athlete designs seek to measure differences in repeated measurements under prescribed conditions, and trend analyses may permit systematic monitoring and prediction of future outcomes. Statistical process control uses control charting and other methods from …
