Dynamic Stability In Gymnasts, Non-Balance Athletes, And Active Controls, Hope Sloanhoffer, Kathryn Harrison, Jean L. Mccrory Phd

International Journal of Exercise Science

International Journal of Exercise Science 11(1): 1-12, 2018. Gymnastics by nature is a balance sport requiring both static and dynamic stability. To our knowledge, the center of pressure (COP) movement of collegiate gymnasts has not been compared to other collegiate athletes and healthy controls during static and dynamic postural stability tasks. Our purpose was to investigate static and dynamic stability in collegiate gymnasts, non-gymnast athletes and non-athlete controls. Data were collected on female university gymnasts (n=10), university athletes in other sports (n=10), and active non-athlete controls (n=10). Static balance was measured using a commercially available six-condition static test and dynamic …

Stigma And Status At An Hbcu: Perceptions Of Racial Authenticity Among Racially Underrepresented Students In The South, Patrick Webb, Le'brian Patrick, Sandra H. Sulzer

Kinesiology and Health Science Faculty Publications

The existence of race-based stigma among minority populations in the United States has been well-documented. Notably, the acting White accusation has garnered considerable attention in relation to the African American population. Interestingly, studies related to this accusation have been primarily centered around Black students at Predominately White Institutions. Comparably, a focus on African American college students at Historically Black Colleges and Universities is limited. The purpose of this study is to determine the extent to which student characteristics (i.e., age, classification) are associated with the acting White accusation. Utilizing a quantitative method design, we analyzed over 100 student surveys which …

Game Spirituality: How Games Tell Us More Than We Might Think, Chad Carlson

Faculty Publications

While we often see games as less serious or at least less transcendental than religion there is reason to believe that games can evoke similarly meaningful narratives that allow us to learn a great deal about ourselves and our world. And games do so often using the same symbolic and metaphorical mechanisms that generate meaning in religious experience. In this paper, I explore some of the ways in which game myths—the myths created from and through games—generate meaning in our lives. People experience myths in games very similarly to how they might in religion. I first explain what myth means …

The Antioxidant Potential Of The Mediterranean Diet In Patients At High Cardiovascular Risk: An In-Depth Review Of The Predimed, Hayley E. Billingsley, Salvatore Carbone

Kinesiology and Health Sciences Publications

Cardiovascular disease (CVD) is the leading global cause of death. Diet is known to be important in the prevention of CVD. The PREDIMED trial tested a relatively low-fat diet versus a high-fat Mediterranean diet (MedDiet) for the primary prevention of CVD. The resulting reduction of the CV composite outcome resulted in a paradigm shift in CV nutrition. Though many dietary factors likely contributed to this effect, this review focuses on the influence of the MedDiet on endogenous antioxidant systems and the effect of dietary polyphenols. Subgroup analysis of the PREDIMED trial revealed increased endogenous antioxidant and decreased pro-oxidant activity in …

The goal of this study is to take a look at the biomechanical behavior of the left atrium and left atrial appendage under normal physiological loading conditions using material properties taken from biaxial stretch tests. Several different options for material properties models were tested and biaxial stretch test data of cadaveric human tissue samples for the left atrium and appendage were fit to a Fung-type strain-energy function for …

The Association Between The Coach-Athlete Relationship And Burnout Among High School Coaches, Scott Westfall, Eric M. Martin, Daniel Gould

Kinesiology Faculty Publications and Presentations

Burnout is a term that continues to raise considerable concern among high school coaches and administrators (Raedeke, 1997) and has shown to have negative effects on coaches and athletes alike (Price & Weiss, 2000; Vealey, Armstrong, & Comar, 1998). While burnout has shown to have significant adverse effects, few studies have examined how the coach-athlete relationship may affect a coach s level of perceived burnout. This study sought to understand if the coach-athlete relationship predicted coach burnout. High school coaches (69 males, 62 females) completed the Coach-Athlete Relationship Questionnaire (CART-Q; Jowett & Ntoumanis, 2004), the Coaching Burnout Questionnaire, a modified …

Repeatability Of The Heart Rate Variability Threshold During Treadmill Exercise, Shane Chambers

Senior Honors Projects, 2010-2019

Purpose: Heart rate variability threshold (HRVT) is a clinical parameter used to gain insight into autonomic balance. Various studies have validated the use of cycle ergometers in determining HRVT, although the literature lacks evidence that treadmill use is a viable means of determining this threshold. We examined the repeatability of HRVT occurrence using standard deviation of normal R-R intervals (SDNN), root mean square of successive differences of continuous R-R intervals (RMSSD), and standard deviation of instantaneous beat intervals (SD1) in college aged males using treadmill exercise to see if this is a reliable method of threshold determination.

Methods: Ten healthy, …

Engineering Hyaluronic Acid Carbon Nanotube Nanofibers: A Peripheral Nerve Interface To Electrically Stimulate Regeneration, Elisabeth M. Steel

Wayne State University Dissertations

Peripheral nerve injuries annually affect hundreds of thousands of people globally. Current treatments like the gold standard autograft and commercially available nerve guide conduits (NGC) are insufficient to repair long gap peripheral nerve injuries. NGCs can aid recovery but lack key microenvironment cues that promote nerve regeneration. We hypothesized that providing topographical, mechanical, and electrical guidance cues through a nanofibrous composite biopolymer would result in improved neuron growth metrics using an in vitro model. We embedded hydrophilic carbon nanotubes (CNT) within hyaluronic acid (HA) nanofibers by electrospinning. The aims of this study were (1) to define the topographical, nanomechanical, and …
