An Analysis Of Future Coaches’ Emerging Dispositions On Social Justice: The Wooden Effect, Brian Culp

Faculty Articles

This qualitative study explored the extent to which an archetype presented through a non-fiction text could impact aspiring coaches’ (AC’s) dispositions regarding social justice. Forty-three aspiring coaches at a Midwestern university enrolled in a foundations class that presented issues related to inequity were studied. Analysis of student journals indicated changes in AC’s philosophies regarding social justice, an appreciation for the perspectives of underrepresented groups and emergent critical perspectives when examining sport processes. Results of the study imply that a focus on democratic education and constructivism in coaching preparation programs may be of benefit. A means by which praxis of this …

Self-Determination Theory As A Pedagogical Foundation For Collegiate Physical Activity Courses, Scot Edward Long

Dissertations

Inactivity, obesity and associated medical, social and economic problems are pervasive in contemporary society. Modern science is aware of the preventative role physical activity offers in deterrence of these problems and the benefits physical education offers. Traditionally, physical education has focused primarily on physiological variables; however, physical activity begins with a behavioral change. Motivation is the necessary factor to initiate physical activity and self-determination theory (SDT) can be used to explain learner motivation in the world of collegiate physical education. Institutionalized schooling is typically performed in a controlling nature, which creates a poor environment for learning and motivation. The purpose …

Dissociation Of The Effects Of Serotonin Reuptake Inhibitor Fluoxetine In Prelimbic Cortex On Disruption Of Timing And Working Memory For Time By Neutral And Negative Emotional Events, Chance Christensen

Undergraduate Honors Capstone Projects

Learning and memory abilities are altered in disorders of the serotonergic system, in disorders such as such as depression, phobias, and post-traumatic stress disorder (PTSD). Among the processes impaired by emotional distracters, and whose dysregulation is documented in affective disorders, is the ability to time in the seconds-to-minutes range, i.e., interval timing. Presentation of distracters during timing tasks result in delays in responding suggesting a failure to maintain subjective time in working memory, as proposed by the Relative Time-Sharing (RTS) model. We investigated the role of the prelimbic cortex in the detrimental effect of anxiety-inducing distracters on the cognitive ability …

Examination Of Different Accelerometer Cut-Points For Assessing Sedentary Behaviors In Children, Youngwon Kim, Jung-Min Lee, Bradley P. Peters, Glenn A. Gaesser, Gregory J. Welk

Health and Kinesiology Faculty Publications

Background: Public health research on sedentary behavior (SB) in youth has heavily relied on accelerometers. However, ithas been limited by the lack of consensus on the most accurate accelerometer cut-points as well as by unknown effectscaused by accelerometer position (wrist vs. hip) and output (single axis vs. multiple axes). The present study systematicallyevaluates classification accuracy of different Actigraph cut-points for classifying SB using hip and wrist-worn monitors andestablishes new cut-points to enable use of the 3-dimensional vector magnitude data (for both hip and wrist placement).
Methods: A total of 125 children ages 7–13 yrs performed 12 randomly selected …

Regularity Of Performance On A Computer Tracking Task Is Different Between Concussed And Non-Concussed Individuals, Kedric James Glenn

Undergraduate Honors Capstone Projects

Concussion in athletics has raised public interest as more is learned about the damage done to the athlete. Some of the current field methods of assessing concussion do not look at neuro-cognitive recover, which can remain impaired long after the symptoms of concussion have passed. Other direct methods of assessing concussion are extremely expensive and are not easily portable.

We created a new assessment for concussion that is relatively inexpensive and portable using non-linear time series analysis of performance on a visual-motor tracking task. Approximate entropy (ApEn) is a tool that enables us to calculate the structure of variability form …

Adolescent Interest And Physical Activity Fluctuation In Technology-Integrated Physical Education, Loren Anne Dragon

Human Movement Studies & Special Education Theses & Dissertations

This study examined the situational interest and physical activity fluctuation of middle school students during technology-integrated physical education. The researcher utilized a quasi-experimental design where 6th grade students were placed into an experiment group that utilized technology-integrated resources during physical education, or a comparison group that did not utilize technology-integration during physical education. The students participated in five physical education lessons with content based upon the conceptual understanding of relative physical activity intensity, heart rate measures, energy expenditure and the FITT principles. Student's physical activity levels were tracked over the five-lesson research period by accelerometers. Situational interest was assessed through …

Comparison Of Body Fat Percentage Results Derived Using Hydrostatic Weighing And The Bod Pod In 185 Women, Rich Jarvis, Dr. Larry Tucker

Journal of Undergraduate Research

Obesity will probably replace cigarette smoking as the major killer of Americans in the next century.1 Research shows that excess body weight leads directly to many health problems, and it often contributes indirectly to other serious diseases by precipitating dangerous metabolic abnormalities.2 In short, obesity plays a central role in the development of numerous diseases, including Type II diabetes, coronary heart disease, high blood pressure, hyperlipidemia, various cancers, osteoarthritis, gallbladder disease, stroke, and all cause mortality.

The Effect Of Adipose Tissue On Intramuscular Temperature Change With Crushed Ice Pack Therapy, J.W. Myrer, Kimberly A. Myrer

Journal of Undergraduate Research

Cryotherapy, the cooling of an injured area, has been used in sports as well as physical therapy since ancient times. In order to be used effectively, a treatment time must be used that will produce optimal physiological effects at a specific tissue depth. As an insulator, adipose tissue has an inverse relationship on intramuscular temperature change. The exact nature of this relationship was the focus of my research.

These problems include heart disease, hypercholesterolemia, hypertension, increased morbidity and mortality from diabetes, and cancer. The National Center for Health Statistics recently reported that 33% of Americans are overweight.

Active Vs. Passive Hamstring Flexibility Tests, Jared W. Papa, Dr. Bent Feland

Journal of Undergraduate Research

Muscle flexibility is “the ability of a muscle to lengthen, allowing one joint (or more than one joint in a series) to move through a range of motion.”1. Various studies have been performed to determine the most reliable and valid means of measuring flexibility, which is important because of its ability to forewarn of the likelihood of injury.2,3 With an indication of the tightness of the muscle a therapist, trainer, or athlete can make necessary adjustments to avoid injury.

Isokinetic, Isotonic, And Isometric Strength Evaluation Measurements And Their Ability To Predict Strength Gains, Jeremy M. Huff, Dr. Kenneth L. Knight

Journal of Undergraduate Research

The use of strength measurements to predict strength gains is commonplace in the rehabilitation community. Athletic trainers, physical therapists and exercise scientists constantly use systems like the Biodex Dynamometer (Biodex Medical Systems, Shirley, N.Y.), to assess the progress of patients undergoing rehabilitation for injuries. Measurements taken on these devices often determine the status of patients permitting or barring them from full activity. Although use of these measurement devices to predict strength gains and functional ability is common, 2,3 some 3,4,5,7question the validity of the measurements. The value of isokinetic training methods has been questioned; 6 however, there has been no …

Neuromuscular Characteristics Before And After Taper In Male Collegiate Swimmers, Michael J. Buys, Dr. Allen Parcel

Journal of Undergraduate Research

An important part of maximizing performance in competitive swimming is a progressive reduction of training before championship competitions called “tapering” (Johns et al. 1992). Because the high volume and intensity of training used during in-season swim workouts may adversely affect muscle strength and performance (Hakkinen et al. 1989; Stone et al. 1984), a short-term reduction in training is used to enhance performance. Tapering involves a significant reduction of duration, intensity and frequency of training over a period of 1-4 weeks. Experimental evidence supports the effects of taper on physiological improvements such as swim power (Costill et al. 1985; Johns et …
