Developing A Computer-Controlled Treat Dispenser For Canine Operant Conditioning, Walker Arce, Jeffrey R. Stevens

Center for Brain, Biology, and Behavior: Faculty Publications

When performing canine operant conditioning studies, the delivery of the reward can be a limiting factor of the study. While there are a few commercially available options for automatically delivering rewards, they generally require manual input, such as using a remote control, in accordance with the experiment script. This means that human reaction times and transmission distances can cause interruptions to the flow of the experiment. The potential for development of non-supervised conditioning studies is limited by this same factor. To remedy this, we retrofitted an off-the-shelf treat dispenser with new electronics that allow it to be remotely controllable as …

Force And Emg Comparison Between A Weight-Bearing Clinical Assessment Of Hip Strength Assessment And Non-Weightbearing Tasks, Kemery J. Sigmund, Jennifer E. Earl-Boehm

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Purpose: Altered hip strength is a risk factor for lower extremity injury but its relationship to biomechanical dysfunction is debated. Hip strength assessment methods are criticized for using unidirectional, non-weight-bearing positions which may not be representative of athletic activity and may affect comparison to biomechanical analysis of athletic tasks. A weight-bearing task may better represent hip muscle function during these movements. The aim of this study was to identify EMG and force differences for a clinical weight-bearing method of hip strength (the squat-hold) to traditional non-weight-bearing maximal voluntary isometric contractions (MVICs) for hip abduction, extension, and external rotation. Methods: Twenty-nine …

Effect Of Age At Menarche On Anterior Cruciate Ligament Injury Incidence And Anterior Knee Laxity In Collegiate Athletes, Andrew W. Froehle, Joseph T. Cox, Jedediah H. May, Kimberly A. Grannis, Dana L. Duren

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Female athletes suffer painful, costly, and career-limiting non-contact anterior cruciate ligament (ACL) injuries more often than males. Previous research suggests that pubertal neuromusculoskeletal development contributes to this sex-bias, but the manner in which variation in pubertal development affects injury risk within females is poorly understood. Age at menarche is a variable, significant pubertal developmental event, signaling the onset of estrogen cycling and affecting musculoskeletal development. Earlier menarche may increase injury risk, possibly by increasing anterior knee laxity through prolonged estrogen exposure. The purpose of this case-control study was to test the primary hypothesis that collegiate athletes with previous ACL injuries …

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

The increase in sport participation among adolescents has led to the rise in sport-related injuries, many of which have unique characteristics based on the patient, their perceptions, and the pressures faced when returning to sport. The purpose of this study was to identify the underlying factors that contributed to adolescents’ perceptions of injury and the various pressures they experienced when returning to sport. Two themes emerged from the study: support and fear. Support was provided to participants through development, care, and the environment. Fear was the factor that affected the participant in their return to sport, which came in the …

Recurrent Patellar Fracture In A Healthy Collegiate Basketball Player: An Exploration Clinical Case Report, Mikaela Boham, Jerry Hilker

Journal of Sports Medicine and Allied Health Sciences: Official Journal of the Ohio Athletic Trainers Association

Recurrent Patellar Fracture in a Healthy Collegiate Basketball Player: An Exploration Clinical Case Report

ABSTRACT

Purpose: Patellar fractures only account for approximately 1% of all skeletal injuries. Patellar fractures usually result from direct trauma (i.e. falling on the knee, dashboard injury, etc.), or, less frequently, occur as a combination of direct and indirect mechanism (i.e. receiving a direct blow while contracting the quadriceps). While indirect trauma is the least common mechanism, it usually occurs due to an extensor mechanism failure during eccentric loading such as landing. Method: Case report, Level 3: Exploration Clinical Contribution to the Available Sources of Evidence …

Sport-Specific Differences In Dynamic Visual Acuity And Gaze Stabilization In Division-I Collegiate Athletes, Carolina Quintana, Nicholas R. Heebner, Anne D. Olson, J. P. Abt, Matthew C. Hoch

Sports Medicine Research Institute Faculty Publications

BACKGROUND: The vestibular-ocular reflex (VOR) integrates the vestibular and ocular systems to maintain gaze during head motion. This reflex is often negatively affected following sport-related concussion. Objective measures of gaze stability, a function mediated by the VOR, such as the computerized dynamic visual acuity test (DVAT) and gaze stabilization test (GST), may have utility in concussion management. However, normative data specific to sport, sex, or concussion history have not been established in collegiate athletes.

OBJECTIVE: The objective of this study was to establish normative values for the DVAT and GST in collegiate athletes and explore the effect of sport, sex, …

Health and Nutritional Sciences Faculty Publications

Upon entering college, students around the United States are exposed to alcohol and the potentially dangerous experiences and ef­fects that come with consuming alcohol. Whether the individual is a general col­lege student or a college student-athlete, the issues are prevalent. According to the 2014 United States Census, there are ap­proximately 23 million students attending U.S. colleges. According to the National Collegiate Athletic Association (NCAA), there are 460,000 student-athletes across the United States (NCAA, 2017). When National Association of Intercollegiate Athletics (NAIA) student-athletes are in­cluded, the overall number then surpasses 500,000. A student-athlete (SA) can be defined as an individual who …

Psychosocial Climates Differentially Predict 12- To 14-Year-Old Competitive Soccer Players’ Goal Orientations, E. Whitney G. Moore, Karen Weiller-Abels

Kinesiology, Health and Sport Studies

Youth’s likelihood of participating in sport increases when they maintain a focus on enjoyment, learning, and effort (i.e., task goal orientation) rather than how they compare to others and norms (i.e., ego goal orientation). Achievement goal theory research consistently illustrates the significant influence of leader-created motivational climates on their participants’ goal orientation adoption. However, the influence of caring climate perceptions by highly competitive adolescent athletes on their goal orientation adoption has yet to be examined. Thus, this study assessed how competitive, adolescent soccer players’ perceptions of the climate as caring, task-, and ego-involving predicted their adoption of task and ego …

Fatigue-Related Feedback From Calf Muscles Impairs Knee Extensor Voluntary Activation, Harrison T. Finn, David S. Kennedy, Simon Green, Janet L. Taylor

Research outputs 2014 to 2021

INTRODUCTION:

Fatigue-related group III/IV muscle afferent firing from agonist, antagonist or distal muscles impairs the ability to drive the elbow flexors maximally, that is, reduces voluntary activation. In the lower limb, the effect of feedback from distal muscles on the proximal knee extensors is unknown. Here, we test whether maintained group III/IV afferent feedback from the plantarflexor muscles reduces voluntary activation of the knee extensors.

METHODS:

On 2 d, voluntary activation of the knee extensors during maximal voluntary contractions (MVCs) was assessed in 12 participants before and after a 3-min fatiguing task of the plantarflexors. On 1 d, an inflatable …

The Effects Of Golf On The Mental Health Of Older Adults: A Content Analysis Of The Literature And A Proposed Future Study, Robert K. Upton Iii

Senior Theses

Through my academic and personal experiences as a student at the University of South Carolina, I developed an interest to research the effects of golf on the mental health of older adults. Physical activity can have many positive results on older adults, including increased cardiorespiratory fitness, decreased risk of chronic diseases, increased longevity, and improved memory and cognition. Golf may be a suitable form of physical activity for older adults, but the relationship between golf and the mental health of older golfers must be investigated. Through a literature review and content analysis of secondary sources, this thesis intends to determine …

Exercise Science Faculty Research and Publications

Masks are an effective tool in combatting the spread of COVID-19, but some people still resist wearing them and mask-wearing behavior has not been experimentally studied in the United States. To understand the demographics of mask wearers and resistors, and the impact of mandates on mask-wearing behavior, we observed shoppers (n = 9935) entering retail stores during periods of June, July, and August 2020. Approximately 41% of the June sample wore a mask. At that time, the odds of an individual wearing a mask increased significantly with age and was also 1.5x greater for females than males. Additionally, the …

The Effects Of Meditation In College Students, Katherine Shelton

Student Theses and Dissertations

Research has been conducted on young student age groups (ages 13-18) and the effects that meditation elicits on anxiety, stress and academic performance, but that is where the age is capped (Beauchemin, Hutchins, & Patterson, 2008). The purpose of this study was to investigate the effects of meditation on a previously understudied age category: undergraduate college students ages 18-22. All participants had their age, gender, height, weight, body mass index, systolic blood pressure, diastolic blood pressure, and resting heart rate measured before and after the study, and completed a 19-Item Body-Image Questionnaire (Koleck, Brunchon-Schweitzer, Cousson-Gélie, Gilliard, & Quintard, 2002).

Center for Brain, Biology, and Behavior: Faculty Publications

Obesity and diabetes are known to be related to cognitive abilities. The Core Neuropsychological Measures for Obesity and Diabetes Trials Project aimed to identify the key cognitive and perceptual domains in which performance can influence treatment outcomes, including predicting, mediating, and moderating treatment outcome and to generate neuropsychological batteries comprised of well-validated, easy-to-administer tests that best measure these key domains. The ultimate goal is to facilitate inclusion of neuropsychological measures in clinical studies and trials so that we can gather more information on potential mediators of obesity and diabetes treatment outcomes. We will present the rationale for the project and …

Winning In Weight-Loss: The Interaction Of Conscientiousness And Perceived Autonomy, Jason M. Curtis, Marc Lochbaum

Journal for Sports Neuroscience

ABSTRACT

Background

Understanding determinants for weight-loss is a national priority. Obesity is an epidemic with serious health consequences. Most of today’s obesity and overweight problems are being attributed to poor diets and not enough physical activity. These problems show no signs of slowing down with the behaviors of most Americans. The phenomenon of “The Biggest Loser” (different variants of weight-loss programs that consist of group exercise participation and nutrition therapy to elicit weight-loss, and hopefully behavior change) has spawned many variants in commercial health clubs. This prospectus study examined the direct and interactive or moderated effects of known determinants of …

Flexible Coordinator And Switcher Hubs For Adaptive Task Control, Carrisa V. Cocuzza, Takuya Ito, Douglas H. Schultz, Dabielle D. Bassett, Michael W. Cole

Center for Brain, Biology, and Behavior: Faculty Publications

Functional connectivity (FC) studies have identified at least two large-scale neural systems that constitute cognitive control networks, the frontoparietal network (FPN) and cingulo-opercular network (CON). Control networks are thought to support goal-directed cognition and behavior. It was previously shown that the FPN flexibly shifts its global connectivity pattern according to task goal, consistent with a “flexible hub” mechanism for cognitive control. Our aim was to build on this finding to develop a functional cartography (a multimetric profile) of control networks in terms of dynamic network properties. We quantified network properties in (male and female) humans using a high-control-demand cognitive paradigm …
