2020 Honors Symposium

INTRODUCTION
• Obesity is an epidemic in the United States (Kim, et. al., 2016).
• Research suggests exercise aids in preventing risk factors that lead to obesity (Cercato, Fonseca, 2019 and Blundell, et. al., 2015).
• Exercise affects appetite regulation, but few studies have explored the effect of exercise on energy intake (Schoeller, et. Al, 1997).

OBJECTIVES
•Compare appetite level changes pre-and post-exercise bout using a Visual Analog Scale (VAS)
•Compare energy intake (food consumption) pre-and post-exercise bout using two 24hour food recalls

Sport In The Face Of The Covid-19 Pandemic: Towards An Agenda For Research In The Sociology Of Sport, Adam B. Evans, Joanna Blackwell, Paddy Dolan, Josef Fahlén, Remco Hoekma, Verena Lenneis, Gareth Mcnarry

Articles

These are extraordinary times. Less because we are currently in the midst of a global pandemic; humanity has been here multiple times in the past, sometimes with even more devastating results (the ‘Black Death’ of 1346–1353, or Cocolitzli Epidemics in the 16th Century, for example). Rather, these are extraordinary times due to both the huge shutting down of industry, travel and borders, and the enormous level of coverage and discussion of the crisis through both traditional and social media formats (Stevens & Prins, 2020). Moreover, global, regional and national comparisons and discussions have become commonplace with regards to everything …

Neural Bases Of Phonological And Semantic Processing In Early Childhood, Avantika Mathur, Douglas H. Schultz, Yingying Wang Dr.

Center for Brain, Biology, and Behavior: Faculty Publications

During the early period of reading development, children gain phonological (letter-to-sound mapping) and semantic knowledge (storage and retrieval of word meaning). Their reading ability changes rapidly, accompanied by learning-induced brain plasticity as they learn to read. This study aims at identifying the neural bases of phonological and semantic processing in early childhood by using a combination of univariate and multivariate pattern analysis. Nineteen typically developing children between the age of five and seven performed visual word-level phonological (rhyming) and semantic (related meaning) judgment tasks during functional magnetic resonance imaging scans. Our multivariate analysis showed that young children with good reading …

Professional Liability Insurance For Athletic Trainers: A Cross Sectional Study Of Athletic Trainers Who Do Per Diem Work, Kameelah J. Belgrave

Honors Undergraduate Theses

Context: Many secondary school athletic trainers (ATs) complete per diem work as a way to supplement their income. Working per diem means the AT provides services to events that are not part of their main employment. Since this type of work is not connected to their main employment, the AT may lack appropriate professional liability insurance (PLI). PLI is a type of insurance that protects healthcare professionals from bearing the entire cost of defending a malpractice claim made by a former or current patient. Anecdotally, many ATs believe that the PLI provided by their main employer covers all health care …

Acute Effects Of Complex Training Using Three Different Intracomplex Rest Intervals On Power Output In Recreationally Trained College Students, Brianna M. Donnelly

West Chester University Master’s Theses

Power is often referred to as explosiveness and is viewed as essential for many athletes within a wide range of sports. Power in sports is important in relation to its foundation in other specific abilities like first step-quickness, acceleration, and reaching top speeds (Cronin, Hansen, 2005). This research study examines the acute effects of complex training using three different intracomplex rest intervals (ICRI) on power output in recreationally trained college students. The goal of this study was to find the optimal ICRI for complex training (CT) by completing a countermovement jump on a force plate after a 3-RM back squat …

Identifying Metabolites As Markers Of Fatigue In Athletes, Christopher D. George

Honors Theses

Fatigue in athletes caused by inadequate rest and other stressors can be severely detrimental to their health, and yet there is no reliable way to measure and track fatigue. Many classical measures of fatigue like body mass and resting heart rate are not reliable ways to track the physical fatigue of an athlete because they can change with many factors. In addition, it is not known how academic stress on top of physical stress affects fatigue. Metabolomics is a relatively new area of study and tracking metabolites offers the possibility to produce biomarkers to assess fatigue. This study collected saliva …
