A Comparison Of Static Stretching Versus Combined Static And Ballistic Stretching In Active Knee Range Of Motion, Nathan R. Blackhurst, James C. Peterson, Valerie W. Herzog, Ericka P. Zimmerman

Internet Journal of Allied Health Sciences and Practice

Background: There is continued controversy related to flexibility gains from different stretching protocols and within single protocols. Stretching methods include static, ballistic, dynamic, and proprioceptive neuromuscular facilitation (PNF). A combination of stretching methods may be an improved way to increase active knee range of motion (ROM). This study evaluated a single program formulated with static and ballistic components. Objective: To compare active knee ROM following stretching programs which either included combined static and ballistic stretching (CSBS) or static stretching (SS) alone. It was hypothesized that CSBS would show a greater increase in active knee ROM than SS. Setting …

Sweat Gland Density And Response During High-Intensity Exercise In Athletes With Spinal Cord Injuries, Robert C. Pritchett, A. M. Al-Nawaiseh, K. K. Pritchett, V. Nethery, P. A. Bishop, J. M. Green

All Faculty Scholarship for the College of the Sciences

Sweat production is crucial for thermoregulation. However, sweating can be problematic for individuals with spinal cord injuries (SCI), as they display a blunting of sudomotor and vasomotor responses below the level of the injury. Sweat gland density and eccrine gland metabolism in SCI are not well understood. Consequently, this study examined sweat lactate (S-LA) (reflective of sweat gland metabolism), active sweat gland density (SGD), and sweat output per gland (S/G) in 7 SCI athletes and 8 able-bodied (AB) controls matched for arm ergometry VO₂peak. A sweat collection device was positioned on the upper scapular and medial calf of …

Emergency Cardiac Care In Athletic Training Education, Erica M. Filep

Masters Theses, 2010-2019

In the field of athletic training, preventing sudden cardiac arrest (SCA) has become a vital component of undergraduate athletic training students’ education. Specifically, SCA is the “leading cause of death in young athletes due to a structural cardiac abnormality” (Casa et. al, 2012, p. 15). Numerous studies about sudden death in athletics have been conducted but there is a gap in educational literature. Teaching students how to respond to catastrophic injury or illness is still an area that needs to be expanded upon. Educational competencies and standards have rapidly evolved with each edition of the National Athletic Trainers’ Association (NATA) …

Men’s ice hockey is a fast and exciting sport that draws elite athletes into its rink. The demands of the sport place athletes at an exceptionally high risk for musculoskeletal injury if they are not properly conditioned. Determining at risk athletes during pre-season screenings is of particular importance to the medical staff, and any opportunity to provide prophylactic treatment is sought after. The purpose of this study was to investigate a potential correlation between a) total FMS scores and total BESS scores, b) total FMS scores and the incidence of injury, c) total BESS scores and the incidence of injury, …

Comparing Before-And After-School Neurocognitive Performance In High School Athletes: Implications For Concussion Management, Anderson Morgan

Health, Human Performance and Recreation Undergraduate Honors Theses

Abstract Background: Sport-related concussion (SRC) continues be a hot topic in sports medicine. Computerized Neurocognitive Testing (CNT) provides researchers and sports medicine professionals an objective way to manage SRC. Administering CNT comes at the convenience of the student athlete and the sports medicine professional working at the school, which usually results in CNT being administered in the afternoon, or after school. However, little is known how the cognitive fatigue of attending a full day of school influences CNT performance. Purpose: The purpose of this study was to compare before school CNT performance to after school CNT performance in a sample …

Prevalence Of Neurocognitive Test Failure Following Exertion In Athletes Recovering From Concussion, Caitlin Laura Zaring

Health, Human Performance and Recreation Undergraduate Honors Theses

The current return-to-play (RTP) protocol in place for an athlete recovering from a concussion is based on the subjective measure of self-report rather than more objective tools such as computerized neurocognitive testing. Because of this, it is possible that athletes downplay or lie about symptoms they are experiencing in order to expedite the RTP process. The purpose of the current study was to examine the frequency of post-exertional neurocognitive test failure in a sample of high school athletes recovering from concussion that underwent a standardized exertional RTP protocol. This research project used a de-identified medical records review of neurocognitive data …

2-Dimension Analysis Of Frontal Plane Projection Angle In Female Soccer Athletes, Kylee M. Tuchfarber

Undergraduate Distinction Papers

Research has found a variety of mechanisms for ACL injuries. One mechanism that has been found is a decreased valgus control at the knee. One study found that that “the decreased active and passive controls of knee alignments may destabilize the knee and are purported to be measures related to increased risk of ACL injury in female athletes, as they mature” (Myer, Ford, Khoury, Succop, & Hewett, 2011, 248). The age of the subjects (12-16) is important because maturation may be a contributing cause of knee abduction moments (KAM). Three-dimensionalanalysis has been said to be the “gold standard” when analyzing …
