Rising Rural Body-Mass Index Is The Main Driver Of The Global Obesity Epidemic In Adults, Con Burns, Tara Coppinger, Janette Walton, Et Al

Publications

Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities1,2. This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity3,4,5,6. Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean BMI segregated by place of residence (a rural or urban area) from 1985 to …

Inducing Incentive Sensitization Of Exercise Reinforcement Among Adults Who Do Not Regularly Exercise—A Randomized Controlled Trial, Kyle D. Flack, Kelsey Elise Ufholz, Luann Johnson, James N. Roemmich

Dietetics and Human Nutrition Faculty Publications

Background

Increasing exercise reinforcement, or decreasing sedentary reinforcement, may reduce sedentary activity and promote habitual exercise. Repeated exposures to a reinforcer may increase its reinforcing value (i.e., incentive sensitization). It is not yet known whether incentive sensitization occurs for exercise or factors associated with incentive sensitization for exercise reinforcement. The purpose was to determine whether exercise exposures increase exercise reinforcement relative to a sedentary alternative and whether this sensitization of exercise reinforcement would alter physical or sedentary behavior. This work also determined whether exercise dose, intensity, and preference and tolerance for exercise intensity were associated with incentive sensitization of exercise. …

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

ETSU Faculty Works

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 …

Innovative Care Of Individuals In The Athletic Training Room: A Case Series, Kathryn E. Young

Senior Honors Projects, 2010-2019

This work follows three unique cases of athletic injuries and/or injuries in patients. These cases were selected because of the innovative nature of the rehabilitation process conducted by the sports medicine team via the athletic training room or the unique nature of the injury/case.

Repetitive Mild Traumatic Brain Injury Impairs Performance In A Rodent Assay Of Cognitive Flexibility, Christopher P. Knapp, Doug P. Fox, Ramesh Raghupathi, Laura L. Giacometti, Stan B. Floresco, Barry D. Waterhouse, Rachel L. Navarra

Rowan-Virtua Research Day

Mild traumatic brain injury (mTBI) occurs in almost 80% of the 3 million reported cases of TBI-related emergency department visits each year in the United States. The majority of mTBIs, sometimes classified as concussions, are due to sports-related activities and typically occur repeatedly over the course of an athlete’s career. mTBI symptoms are generally classified as either somatic or neuropsychiatric/cognitive in nature and include impairments in prefrontal cortex mediated functions, including attention, memory, processing speed, reaction times, problem solving, and cognitive flexibility. To date, there remains a major gap in our understanding of the behavioral manifestations, underlying neurobiology, and treatment …

Keeping Campuses Safe: The College Crime And Consequence Conundrum, Richard L. Bailey Jd, Kristy Mccray

Health and Sport Sciences Faculty Scholarship

Recent cases of sexual assault and violence against women proliferate in intercollegiate athletics. Despite federal mandates under Title IX, universities may struggle to appropriately respond to such incidences due to fan bias and/or difficulty in prosecuting under the criminal burden of proof. As such, this article offers up the National Collegiate Athletic Association (NCAA) as an adjudicating body, which could appoint a tribunal to ensure safety on campus and just punishment for transgressors. Using retributive justice and procedural justice as theoretical frameworks, it is argued that the NCAA is best served to investigate instances of sexual assault and violence against …

Serial Neuropsychological Assessment Toward A Reliable Concussion Protocol, Daniel J. Soden

Doctor of Psychology (PsyD)

With more than 10,000 Sports Related Concussions (SRCs) per year at the collegiate level, interdisciplinary teams are often tasked with determining when an athlete may return to activity (Zuckerman et al., 2015). Due to neurochemical changes following an SRC, athletes are vulnerable to further injury if they suffer another head injury before given appropriate time to heal (Giza & Hovda, 2014). Cognitive testing is routinely utilized to detect the presence of cognitive dysfunction and aid in individualized treatment planning. Because athletes often demonstrate practice effects when retested, it is difficult to distinguish if the athlete is demonstrating cognitive dysfunction. Reliable …
