Comparing The Cost Effectiveness Of A Celiac Disease Panel To A Testing Cascade, Caleb Bazyler, Kevin Breuel Feb 2019

Comparing The Cost Effectiveness Of A Celiac Disease Panel To A Testing Cascade, Caleb Bazyler, Kevin Breuel

Caleb D. Bazyler

Recent reductions in healthcare funding in the United States has pressured clinical laboratories to provide the same quality of diagnostic testing with fewer resources. Testing cascades have been developed to assist in the diagnosis of various illnesses, which use fewer tests and subsequently reduce costs. However, the cost effectiveness of a celiac disease (CD) testing cascade compared to a panel is currently unknown. Therefore, the purpose of this study was to determine if a CD testing cascade was equivalent to a panel in identifying patients deemed likely for CD, and to compare their cost effectiveness in a sample of symptomatic …


Cell Free Dna As A Marker Of Training Status In Weightlifters, Jeremy A. Gentles, William G. Hornsby, Christine L. Coniglio, Andy R. Dotterweich, Jon A. Miller, Charles A. Stuart, Michael H. Stone Feb 2019

Cell Free Dna As A Marker Of Training Status In Weightlifters, Jeremy A. Gentles, William G. Hornsby, Christine L. Coniglio, Andy R. Dotterweich, Jon A. Miller, Charles A. Stuart, Michael H. Stone

The purpose of this investigation was to elucidate the changes in cf-DNA as it relates to fluctuations in resistance training workloads and intensities. The relationship between cell free DNA (cf-DNA), C-reactive protein (CRP), creatine kinase (CK), testosterone (T), cortisol (C), testosterone-cortisol ratio (T:C), body mass and body composition were also examined. Eight weightlifters (5 males and 3 females, age = 25 ± 3.5 yr, body mass = 88.3 ± 22.7 kg, height = 173.8 ±8.4 cm) volunteered to participate in this study. Venous blood samples, body mass and body composition were taken six times, each corresponding to the end of …


Can You Float? Part 2 - Perceptions And Practice Of Lifejacket Use Among Young Adults, Kevin Moran Ph.D. Feb 2019

Can You Float? Part 2 - Perceptions And Practice Of Lifejacket Use Among Young Adults, Kevin Moran Ph.D.

International Journal of Aquatic Research and Education

Personal flotation devices (PFDs), commonly referred to as lifejackets, have been identified as an extremely effective form of drowning prevention and was identified as a critical distinct water competency by Stallman and colleagues (2017). In this second phase of the Can You Float? study, perceptions and practice of a range of lifejacket tasks among students (N = 40) with known water proficiency were examined. Participants estimated exertion levels before and after practical testing of six simulated survival tasks when wearing lifejackets. All participants completed a 25m sprint swim, 5-minute endurance swim, 5-minute float, and 25m partner assist but many …


An Investigation Of Youth Swimming Skills And Method Of Instruction, Carol C. Irwin, Jennifer R. Pharr, Todd E. Layne, Richard L. Irwin Feb 2019

An Investigation Of Youth Swimming Skills And Method Of Instruction, Carol C. Irwin, Jennifer R. Pharr, Todd E. Layne, Richard L. Irwin

International Journal of Aquatic Research and Education

Drowning is a leading cause of death for US children. Teaching youth to swim in a formal setting from certified instructors is a consistent drowning prevention recommendation. Purposes for this investigation was to examine type of swimming instruction and ability to swim and compare to attitudes toward swimming among US youth. Methods were similar to previous USA Swimming studies in 2008 and 2010. YMCA associations in five cities were used to recruit adolescent survey respondents (n=600) aged 12-18 years. Results showed African American youth had the lowest rate of formal swimming instruction (29%) compared to White (32%) and Hispanic (42%) …


Solution-Focused Therapy Changes Neurophysiological Activation In Collegiate Athletes: An Intervention Study, Kyler T. Shumway Feb 2019

Solution-Focused Therapy Changes Neurophysiological Activation In Collegiate Athletes: An Intervention Study, Kyler T. Shumway

Doctor of Psychology (PsyD)

Neurophysiological research has begun to uncover how therapy produces change in the brain. To examine this phenomenon, many studies have controlled for specific symptoms to identify where therapy has the greatest effect (Linden, 2006). In athletic performance, anxiety represents a significant struggle for college athletes (Mabweazara, Leach, & Andrews, 2017). The present study intended to examine the impact of brief therapy on brain activation and competition anxiety in college athletes. A sample of collegiate athletes (n = 17) participated in a pre-post intervention study. Pre- and post-intervention measures included electroencephalogram (EEG), galvanic skin response (GSR), self-report anxiety measures (SAS-2, GAD-7), …


Association Between Perceived Physical Activity And Cognitive Function In Older Adults, Paul D. Loprinzi, Emily Frith Feb 2019

Association Between Perceived Physical Activity And Cognitive Function In Older Adults, Paul D. Loprinzi, Emily Frith

Faculty and Student Publications

© The Author(s) 2018. There is irrefutable evidence that regular participation in physical activity is favorably associated with numerous positive health outcomes, including cognitive function. Emerging work suggests that perceived physical activity, independent of actual physical activity behavior, is inversely associated with mortality risk. In this study, we evaluate whether perceived physical activity, independent of actual physical activity, is associated with cognitive function, a robust indicator of mortality risk. Data from the cross-sectional 1999–2002 National Health and Nutrition Examination Survey were employed (N = 2352; 60+ years of age). Actual physical activity was assessed via a validated survey. Perceived physical …


Revised Scientific Review: Minimum Age For Swim Lessons, Stephen J. Langendorfer Ph.D. Jan 2019

Revised Scientific Review: Minimum Age For Swim Lessons, Stephen J. Langendorfer Ph.D.

International Journal of Aquatic Research and Education

The question addressed in the original scientific review (2009) was rephrased as Does sufficient scientific evidence exist to support setting a minimum age for swimming lessons? for this triennial review. Addressing the research question is significant because strong differences of opinion about the appropriate age(s) for initiating learn-to-swim lessons have existed among the pediatric medical profession, aquatic professionals and agencies, and proprietary programs and swim schools for over four decades. The question has implications for the appropriate purposes, pedagogies, and outcomes associated with swimming experiences for infants and young children that will be addressed in a subsequent review. The revised …


Acute Exercise And Mindfulness Meditation On Learning And Memory: Randomized Controlled Intervention, Malina Austin, Paul D. Loprinzi Jan 2019

Acute Exercise And Mindfulness Meditation On Learning And Memory: Randomized Controlled Intervention, Malina Austin, Paul D. Loprinzi

Faculty and Student Publications

© 2019 The Author(s). Background: The purpose of this experiment was to evaluate the potential combined effects of acute exercise and mindfulness mediation on episodic memory. Methods: All data collection occurred in the authors’ laboratory (January to May of 2019). In this three-arm, within-subject design, participants (N=20; Mage=21.6 years) completed three counterbalanced laboratory visits, including Exercise Only, Exercise + Meditation and Control. Learning and memory were assessed from a word-list task. A one-factor repeated-measures ANOVA was computed for two memory outcomes, including the learning outcome (average performance across the 6 trials) and the long-term memory recall (10-minute delay). Results: The …


The Manifestations Of Fatigue In Amateur Boxing Performance, Emily C. Dunn Jan 2019

The Manifestations Of Fatigue In Amateur Boxing Performance, Emily C. Dunn

Theses: Doctorates and Masters

A subjective method of judgment, the “Ten Point Must-System” (TPMS), was introduced into amateur boxing in 2013. To be successful, boxers must deliver forceful punches and exert dominance over an opponent. There has been limited research examining the strategies used by boxers to win fights under the TPMS and whether these strategies induce fatigue that is sufficient to significantly affect punch force. The overall objective of the five studies contained in this thesis was to describe, in relation to fatigue, the performance characteristics of male amateur boxers under the TPMS, and improve our understanding of the physical characteristics associated with …
