During a season, baseball players experience prolonged bouts of high intensity activity that increase the need for recovery and sleep. Athletes can also experience higher perceived stress levels, a factor also known to impact sleep. Reduced sleep quality and quantity during a competitive season can impede recovery and decrease performance. The present study sought to determine the relationships between sleep [Total Sleep Time (TST), Sleep Efficiency (SE), Sleep Onset Latency (SOL), Awakenings] and stress over a …

Extensor Hallucis Longus Focal Dystonia In A Patient With Parkinson’S Disease: A Case Study, Jessika Truax, Linda Bobo, Keilea Sumrall

Clinical Practice in Athletic Training

Introduction: Parkinson’s Disease (PD) is a common neurodegenerative disorder that affects a person’s ability to produce dopamine and control motion of the body. PD affects 1% of people over the age of 65, but the disease can occur earlier and later in life. The uncontrollable movement of any body part involved with PD is referred to as a tremor. Pathophysiology of PD causes the thalamus to have a decreased activation of the frontal cortex, thus decreased motor activity. Patients commonly have dystonia mostly in the foot resulting in striatal toe. Optional pain relief is a tenotomy of the extensor hallicus …

Sacroiliac Dysfunction In A Middle-Aged Female Runner: A Case Study, Blair Bradshaw

Clinical Practice in Athletic Training

Introduction: Research has indicated an increased prevalence of low back pain (LBP) due to SIJ dysfunction, with some reports suggesting it is the main source of pain in 15- 30% of cases. Women are more prone to incidence of SIJ pain due to a wider, more uneven, less curved, and posteriorly rotated sacrum. Additionally, women have increased mobility at the SIJ which increases stress and shear loading. Repetitive loading such as running can further contribute to SIJ dysfunction. Research suggests that female runners with SIJ pain had common biomechanical patterns putting them at more risk for injury including decreased knee …

Predicting Tilt In Esports: A Psychophysiological Approach To Understanding Player Emotional Regulation, Nathan Rhea

University of the Pacific Theses and Dissertations

Emotional regulation and stress management are important to both casual and competitive esports players. When players become dysregulated, they experience a phenomenon known as “tilt” within the gaming community, where they often lose control of their emotions and their performance declines. This study aimed to investigate whether a psychophysiological variable in heart rate variability could predict tilt in college-age esports players. Additionally, the relationship between heart rate variability and emotions predicted by the Tiltometer system with gameplay performance and winning or losing was tested.

This study used a quantitative correlational research design. Participants for this study were college-age players (N=23) …

The Autonomic And Arrhythmogenic Effects Of Gestational E-Cigarette Exposure., Brittany Rachelle Reynolds

Electronic Theses and Dissertations

Introduction. E-cigarettes (e-cigs) have been shown to be pro-arrhythmic in both human and male rodent studies; however, little is known about how e-cig use impacts patients with a predisposed heightened risk for arrhythmias, including pregnant women. Both pregnancy and e-cig use have independently been shown to increase heart rate, diminish heart rate variability, and increase ventricular premature beats, which is suspected to be due to sympathetic dominance. Importantly, β-blockers have been shown to reduce sympathetic activity, reduce heart rate, increase HRV, and reduce arrhythmias. Thus, the use of β-blockers may help prevent adverse health effects driven by sympathetic dominance from …

The Science Of Sound: Studying The Cognitive, Emotional, And Physiological Effects Of Frequency, Genre, And Music, Jett Yarborough

Senior Honors Theses

Music influences emotion, physiology, and cognition, yet little is known about how the frequency it is tuned to affects these influences. Prior research has shown that music tuned to 432 Hz can reduce stress, lower blood pressure, and improve sleep. My colleagues and I conducted two studies to investigate this. Our research found that music tuned to 432 Hz promotes a significant increase in memory retention and induces a state of focus and relaxation. These results suggest that shifting from the standard tuning frequency of 440 Hz to 432 Hz could have a profoundly positive impact on our daily lives. …

Impact Of A Focused Best Practice Workshop On Athletic Trainer Confidence, Jaclyn B. Arduini, Jennifer L. Volberding, Zachary A. Murray

Clinical Practice in Athletic Training

Athletic trainers are required to be proficient in emergency management skills, without review these skills may decay creating a potentially dangerous knowledge gap. Confidence measures of emergency management skills were taken before and after a workshop to determine if they changed due to the review of material. All 11 confidence measures increased post workshop, seven significantly, including rectal temperature, hemostatic agents, external hemostatic modalities, in-line stabilization, measurement and application of a cervical collar, football and other equipment removal. ATs should aim to incorporate emergency management review into continuing education choices.
