An Examination Of Athletic Directors' Perceptions Of The Utilization Of Athletic Trainers In The Secondary School Setting, Stephanie H. Clines

Health Services Research Dissertations

Many secondary school athletes are lacking appropriate medical care during sport participation. Athletic trainers (ATs) are qualified healthcare professionals that can fill this need. Barriers to hiring ATs within this setting have been identified, however important information from administrators is lacking on why secondary schools choose to utilize ATs. Understanding this decision making process has the potential to guide future strategies to increase the number of secondary schools that employ ATs and improve retention of athletic training positions within the secondary school setting.

Our objective was to explore athletic directors’ perceptions of the roles and services provided by ATs working …

Background: Long term neurologic injury and concussion have been identified as risks from participation in American football. Altering tackling form has been recommended to reduce the risk of neurologic injury caused by head accelerations when tackling. The purpose of this research is to determine the inter-rater agreement and validity of the Qualitative Youth Tackling System (QYTS), a six-item feedback scale to correct tackling form, when utilized by novice and expert raters.

Hypothesis: Experienced raters will have higher levels of agreement with each other and with motion capture when compared to novice raters. Methods: Both novice and experienced raters viewed video …

Athletic Training Student Core Competency Implementation During Patient Encounters, Julie M. Cavallario, Bonnie L. Van Lunen, Johanna M. Hoch, Matthew Hoch, Sarah A. Manspeaker, Shana L. Pribesh

Rehabilitation Sciences Faculty Publications

Context: Health care research evidence suggests that early patient encounters (PEs), as well as the purposeful implementation of professional core competencies (CCs), for athletic training students (ATSs) may be beneficial to their ability to provide care. However, no investigators have related facets of the clinical education experience with CC implementation as a form of summative assessment of the clinical experience.

Objective: To determine the relationship between the frequency and length of PEs, as well as the student's role and clinical site during PEs, and the students' perceived CC implementation during these encounters.

Design: Cross-sectional study.

Setting: Professional athletic training program, …

Postprofessional Athletic Training Students' Perceptions Concerning The Health Care Competencies, Cailee E. Welch Bacon, Bonnie L. Van Lunen, Dorice A. Hankemeier

Rehabilitation Sciences Faculty Publications

Context: Over a decade ago, the Institute of Medicine indicated that all health care professionals should be educated in several health care competency areas (quality improvement, health care informatics, interprofessional education and collaborative practice, evidence-based practice, and patient-centered care). Despite this initiative, athletic training has only recently incorporated these competencies throughout education.

Objective: To assess postprofessional athletic training students' perceived abilities and importance regarding 6 core competencies.

Design: Cross-sectional. Setting: Self-reported paper survey. Patients or Other

Participants: A total of 221 from a convenience sample of 258 postprofessional athletic training students (85.7%) completed the survey (82 males, 138 females; age …

Association Between Vitamin D Status And Testosterone And Cortisol In Ice Hockey Players, John S. Fitzgerald, Joanna Orysiak, Patrick B. Wilson, Joanna Mazur-Różycka, Zbigniew Obinski

Human Movement Sciences & Special Education Faculty Publications

The identification of the vitamin D receptor in tissues related to testosterone and cortisol production, in conjunction with the observed correlations between vitamin D levels and these hormones in the general population, suggest vitamin D may influence testosterone and cortisol concentrations in athletes. A crosssectional study design was used to evaluate the association between 25(OH)D and testosterone and cortisol concentrations in young male ice hockey players (n = 50). All athletes were recruited during October from the Sosnowiec area, Poland (50° N). Commercially available ELISA kits were used to determine total serum 25(OH)D, testosterone and cortisol concentrations. Serum 25(OH)D …

Youth Leisure-Time Physical Activity From The Perspectives Of Young Adults With Visual Impairments, Justin A. Haegele

Human Movement Sciences & Special Education Faculty Publications

The purpose of this study was to examine the meaning that young adults with visual impairments ascribe to their youth leisure-time physical activity experiences. This study adopted an interpretative phenomenological analysis (IPA) research approach. Ten participants (aged 21-34 years; eight women, two men) with visual impairments were included in this study. Semi-structured, audio-taped telephone interviews acted as the primary source of data for this study. Data were analyzed thematically using a four-step process informed by IPA and three interrelated themes were constructed: (a) "I just always felt normal when I was doing them": Preferences for unstructured activities, (b) "They didn't …

The Effect Of Tackling Training On Head Accelerations In Youth American Football, Eric Schussler, Richard J. Jagacinski, Susan E. White, Ajit M. Chaudhari, John A. Buford, James A. Onate

Rehabilitation Sciences Faculty Publications
