Current Research And Statistical Practices In Sport Science And A Need For Change, Jake R. Bernards, Kimitake Sato, G. Gregory Haff, Caleb D. Bazyler 2019 East Tennessee State University

Current Research And Statistical Practices In Sport Science And A Need For Change, Jake R. Bernards, Kimitake Sato, G. Gregory Haff, Caleb D. Bazyler

Caleb D. Bazyler

Current research ideologies in sport science allow for the possibility of investigators producing statistically significant results to help fit the outcome into a predetermined theory. Additionally, under the current Neyman-Pearson statistical structure, some argue that null hypothesis significant testing (NHST) under the frequentist approach is flawed, regardless. For example, a p-value is unable to measure the probability that the studied hypothesis is true, unable to measure the size of an effect or the importance of a result, and unable to provide a good measure of evidence regarding a model or hypothesis. Many of these downfalls are key questions researchers strive ...

Conceptually, it is important to understand the underlying physiological mechanisms of any training program model. This understanding aids the coach/sport scientist in making better choices in manipulating variables in formulating the training model. These underlying mechanisms can be associated with training variable manipulation and fatigue management aspects as well as the overall health of the athlete. Hormone and cytokine concentrations can be linked to alterations resulting from the manipulation of training variables and to subsequent alterations in performance (Haff et al., 2008; Ishigaki et al., 2005; Jurimae et al., 2010; Stone et al., 2007). For example, alterations in the ...

Seasonal Changes In Sleep, Rpe, And Scoring Percentage In Division One Collegiate Female Basketball Players, Lindsay Perrin, Dr. Stephen Rossi 2019 Georgia Southern University

Seasonal Changes In Sleep, Rpe, And Scoring Percentage In Division One Collegiate Female Basketball Players, Lindsay Perrin, Dr. Stephen Rossi

University Honors Program Theses

Basketball season occurs over several months and involves heavy traveling, training, competing, and scholarly duties. These demands do not allow much time for rest and recovery. A lack in the quantity and quality of sleep can reduce the ability to manage stress and reduce recovery from training and competition. This can affect the health and well-being of the athlete and their success on the court. In college, sleep schedules may change from high school by staying up later and sleeping in more. College students typically sleep between six and seven hours a night which is less than the recommended nine ...

Coaches' Preparedness For Sudden Death Conditions In Secondary School Athletics In West Virginia, Jillian Mary Sarm

Graduate Theses, Dissertations, and Problem Reports

Context: Coaches in the secondary school setting may encounter and be expected to provide emergency medical care for student athletes in the absence of a healthcare professional such as athletic trainers. The National Athletic Trainers’ Association (NATA) categorized ten sudden death conditions which are common in athletics and may warrant a medical emergency. Since the coaches may not be cognizant of these common sudden death conditions, they may not be prepared to handle a medical emergency which threatens the life of student athletes. Objective: Determine if West Virginia Secondary School Activities Commission (WVSSAC) coaches are aware and prepared to provide ...


Organizational Models In Athletic Training And The Effect On The Quality Of Care Delivered, Matthew Ferreira 2019 West Virginia University

Organizational Models In Athletic Training And The Effect On The Quality Of Care Delivered, Matthew Ferreira

Graduate Theses, Dissertations, and Problem Reports

Context: Quality of care is an ethical priority to all healthcare professionals. Healthcare fields such as nursing and physical therapy have made changes in staff size and focus that have increased the quality of care provided to patients. The athletic training field has not made changes to the organizational structure. Thus, the quality of care delivered by athletic trainers is an understudied topic. Likewise, the organizational models have just recently been explored in the literature. Objective: Identify differences in the three models of organization (academic, athletic, and medical) related to quality of care delivered and coverage versus care. Design: This ...

'I Think I'M Gonna Hurl': A Narrative Review Of The Causes Of Nausea And Vomiting In Sport, Patrick B. Wilson

Counseling & Human Services Faculty Publications

Exercise-associated gastrointestinal (GI) distress can negatively impact athletic performance and interfere with exercise training. Although there are a few universal underlying causes of GI distress, each symptom often has its own unique triggers and, therefore, its own prevention and management strategies. One of the most troubling GI symptoms an athlete can experience during training and competition is nausea/vomiting. The prevalence of nausea varies with several factors, two of the most important being exercise intensity and duration. Relatively brief, high-intensity exercise (e.g., sprinting, tempo runs) and ultra-endurance exercise are both associated with more frequent and severe nausea. The potential ...
