Reaction Time Under Limited Vision With Cognitive Challenge In Individuals With Anterior Cruciate Ligament Reconstruction, Hsuan Bonny Lu

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

The anterior cruciate ligament (ACL) rupture is a common sports injury. ACL reconstruction (ACLR) is a necessary treatment for individuals to return to competitive sports. However, a high rate of secondary injury occurs when individuals return to sport. Past research has shown that ACLR impairs physical performance, including reduction of force generate against the floor under the injured leg, changes in the gait pattern, and a loss of knee stability. While structural changes following ACL injury can leave the knee joint less stable, neurophysiological changes following ACL injury represent one potentially important mechanism underlying the performance deficits. Healthy individuals rely …

Relationships Between Muscle Characteristics And Step Outcomes In Young And Old Adults, Kareem Abubukker

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

Background: Falls are a primary cause of mortality and morbidity in older adults. In an effort to assess falls, a number of studies have measured neurological, biomechanical, and neuromuscular function in relation to fall risk. Despite efforts, falls continue to affect the older adult population leading to subsequent impaired mobility and function. Multiple factors contribute to fall risk among older adults, however, a factor that has shown a consistent relationship with the prevalence of future falls is reduced muscle characteristics. Moreover, the ability to rapidly accelerate a limb, as captured by rate of power development (RPD), rate of velocity development …

Prefrontal Activation During Inhibition Of A Balance Recovery Step, Ezinne Abugu

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

The ability to quickly step is an important strategy to avoid a fall. However, real-world settings often constrain a stepping path. Such constraints necessitate response inhibition to prevent an inappropriate step and select a new course of action to ultimately recover balance. The present study investigated neural mechanisms that underlie this ability to stop a highly automatic balance recovery step. In the field of cognitive neuroscience, response inhibition has typically been researched using focal hand reaction tasks performed by seated participants. This approach combined with neuroimaging has revealed a neural stopping network, which includes the right Inferior Frontal Gyrus (right …

Effects Of Imu Sensor Location And Number On The Validity Of Vertical Acceleration Time-Series Data In Countermovement Jumping, Dianne Althouse

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

Many devices are available for measuring the height of a CMJ. An inertial measurement unit (IMU) measures linear acceleration, orientation, and angular velocity. As an alternative to using IMU estimates of flight time, CMJ height could be estimated by integrating the IMU time-series signal for vertical acceleration to derive CMJ take-off velocity in order to track whole-body center of mass (WBCoM) movement, yet this approach would require valid IMU acceleration data. Thus, the purpose of this study was to quantify the effects of IMU sensor location and number on the validity of vertical acceleration estimation in CMJ. Thirty young adults …

Association Between Visuomotor Skills And The Effects Of Stroboscopic Vision On Depth Jump Performance, Riley Welch

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

The reactive strength index (RSI) is a popularized method of evaluating depth jump performance. Performance in anticipation of ground impact is influenced by the proprioceptive, vestibular, and visuomotor systems through multisensory integration. The contribution of vision to depth jump performance has been studied through use of stroboscopic goggles, but no study has evaluated which visuomotor skills may be a predictor for DJ performance. The purpose of this investigation was to evaluate the association between visuomotor skills and the effects of stroboscopic vision on DJ performance. Participants consisted of 9 female and 13 male college aged adults. DJ performance was evaluated …

Comparative Effects Of Eccentric Overload Training On Muscle Function Measures When Combined With Aquatic Plyometric Training, Cassidy Weeks

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

Although there is a growing body of knowledge on eccentric resistance training and aquatic plyometric training on muscle function measures alone, no research to date has investigated the effects of a mixed training model. Aquatic plyometrics and overload eccentric training are two different training models which could work synergistically because the shortcomings of one model are the virtues of the other (i.e., plyometrics are not as effective at producing large muscle size and strength gains and eccentric-only training largely lacks the functional SSC component). The purpose of this study was to examine and compare the effects of a combined eccentric …

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 …

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 …

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 …

Effects Of A Telerehabilitation Group On Continuing Language Treatment After Participation In An Intensive Comprehensive Aphasia Program (Icap), Alexis Missel

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

Aphasia is an acquired neurogenic language disorder encompassing oral and/or written language expression and comprehension affecting an estimated two- to two to four million people in the United States, (Simmons-Mackie, 2018; National Aphasia Association, 2016). The primary aim of the current study was to investigate an option for targeted intervention as a follow-up to an Intensive Comprehensive Aphasia Program (ICAP). There is little research assessing maintenance of communication profile gains following conclusion of the ICAPs, and there are few options that exist as tailored ICAP follow-up programs or continued intervention guided by the ICAP principle features. To address this, a …

Modern Yoga In America, Emily Parkinson Perry

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

Yoga’s immense growth and popularity during the twentieth and twenty-first centuries, along with its proliferation into countless varieties and styles, presents teachers, students, and scholars with the question: “What is yoga?” Answering this question requires the investigation of a number of cultural, historical and philosophical tensions at play in modern expressions of this ancient tradition: (1) Is modern postural yoga (MPY)—the yoga widely practiced in studios across the country today—an authentic expression of yoga or is it simply another form of physical fitness? (2) Does the modern focus on the physical dimension of yoga forsake its original purpose of …

Piloting A Cooking Demonstration Curriculum For Dietetics Students, Jill Henderson

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

Cooking demonstrations are a unique and effective way to teach nutritional concepts and basic cooking skills in a community setting. They have been found to be beneficial for participants in attendance as they improve confidence in the kitchen, cooking skills development, and the promotion of healthier foods into the diet. Classroom learning facilitates critical thinking but does not necessarily provide a platform for hands-on learning. In planning and executing community-involved cooking demonstrations, students are able to connect content learned in the classroom to professional practice. Over the last decade the field of dietetics has involved more community-based programs designed to …

The Effects Of A Yoga Intervention On Reactive Balance In Older Adults, Haley M. Hayes

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