Comparative Metabolism Of Aflatoxin B1 In Two Quail Genera Coturnix Japonica And Callipepla Californica, Sean Moody

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Avian species are highly susceptible to the hepatotoxic mycotoxin aflatoxin B₁ (AFB₁). Domesticated turkeys are exquisitely sensitive, due to a combination of highly-efficient hepatic cytochrome P450 (CYP)-mediated bioactivation, and to dysfunctional alpha-class glutathione S-transferases (GSTAs) which typically detoxify the bioactivated electrophilic metabolite exo-AFB₁-8,9-epoxide (AFBO). Wild turkeys are relatively resistant to AFB₁ in large part due to expression of functional GSTAs. Quail, a related Galliforme, are slightly less sensitive in vivo to AFB₁, but whether this is related to the hepatic metabolic profiles of these two critical enzymes has not been rigorously evaluated. …

Transfer Effects Of A Multiple-Joint Isokinetic Eccentric Training Intervention To Nontraining-Specific Traditional Muscle Function Measures, Steven Spencer

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The transfer effects of isokinetic, eccentric-only resistance training programs on non-specific measures of muscle function such as isometric peak force, isokinetic concentric peak force and dynamic constant external resistance 1-repetition maximal strength (DCER 1RM) have been researched extensively in a single joint context, yielding mixed results. However, investigations involving multiple-joint isokinetic eccentric-only training models have been sparse. The purpose of this study was to investigate the transfer effects of a short-term multiple-joint isokinetic eccentric leg press (Eccentron) training program on several measures of lower-body strength and performance. Fifteen participants performed Eccentron training three times/week for four weeks and were evaluated …

Survey Of Ncaa Athletic Trainers’ Administration Of The National Wrestling Coaches Association Weight Certification Program, Samuel Konrath

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Context: The National Collegiate Athletic Association (NCAA) implemented a minimum weight certification program in 1997 to help protect wrestlers from dangerous weight loss practices. Despite nearly a quarter of a century of this program, there is no published research detailing the implementation of it.

Objective: Determine how the NCAA minimum weight certification is being implemented across Division I programs.

Design: Cross-sectional study

Setting: Survey

Patients or Other Participants: A total of 35 (45.5%) of 77 NCAA division I wrestling athletic trainers responded to the survey.

Main Outcome Measure(s): Survey data on how the NCAA minimum weight certification program was implemented …

Test-Retest Of The 5-Minute Psychomotor Vigilance Test, Katharine Dennison

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The purpose of this study was to evaluate the reliability of many variables in the 5-minute Psychomotor Vigilance Test (PVT). Many studies have looked at the validity of a 5-minute PVT, but few so far have looked at reliability. For this study, 13 adult females who worked 12-hr shifts were recruited to complete a two trial day study. The first trial day, the subjects submitted health questionnaire followed by a self-reported sleepiness scale and then a 5-minute PVT. The second trial session the subjects only competed the sleepiness scale followed by the 5-minute PVT. After analyzing the data, it was …

No Evidence Of Stochastic Resonance In Postural Sway Response To Noisy Galvanic Vestibular Stimulation In Healthy Young Adults, Dominique Rice

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The transcutaneous application of a sub-sensory electrical stimulation to the vestibular afferents, known as noisy galvanic vestibular stimulation (nGVS), is thought to cause a reduction in postural sway at optimal amplitude intensities due to a mechanism known as stochastic resonance (SR). SR is a phenomenon whereby the addition of low amplitude noise to a non-linear system can be beneficial rather than detrimental. In humans, behavioral markers of SR in postural sway have been inconsistent, potentially due to insufficient power or false positives. Therefore, the main purpose of this study was to determine whether the frequency of observing SR-like effects improves …

Mindfulness-Based Practices For The Impaired Performance Athlete, Mackenzie L. Campbell

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Mindfulness-based programs are becoming commonly considered for the improvement of athlete's mental and physical state. However, their usage in improving performance in impaired athletes is limited and not fully understood. The purpose of this thesis was to review the standing literature on the topic of the application of mindfulness to improving athletic performance in wellbeing-impaired athletes. Seventy-three articles were included as references for this paper describing functional mechanisms, clinical significance and anecdotal evidence that points to the effectiveness of mindfulness in sport for the treatment of pain, injury recovery, prevention of injury, and chronic illness. Ultimately, this review supports the …

The Wingate Anaerobic Test: A Comprehensive Literature Review And Update On Reference Values In Athletes, Caleb Christie

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Wingate Anaerobic test (WAnT) was developed in the 1970s as a measurement of lower extremity anaerobic power (Ayalon, Inbar, Bar-Or, 1974) and has long been used as a measurement tool in athletes, who are often defined by numbers. While numbers are not able to entirely predict or evaluate athletic ability, they are often used as a tool to predict or rate athletes. The WAnT has long been a gold standard in evaluating lower extremity power, which is a highly valuable aspect of many sprint and power-driven sports (e.g., hockey, football, or track and field). The WAnT was originally developed …

Improving The Specificity Of Vertical Stiffness Measurement In Depth Jump Landings, Miles Mercer

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Greater lower extremity stiffness has been shown to increase bilateral jump height through stretch-shortening cycle optimization. Currently, there are two established methods for estimating vertical stiffness (K_vert) of the human body, which is a variant of lower extremity stiffness. The validity of these methods for estimating K_vert in non-cyclical human movements has been questioned recently due to the complex physiological and neuromotor factors that support stiffness regulation in the muscle-tendon complex. The purpose of the present study was to improve the specificity of K_vert measurement using direct derivation of vertical ground reaction force (GRF) and center …
