Modulation Of Vestibular Evoked Reflexes In Postural Muscles During Self-Motion Experiences In Virtual Environments, Fabricio Saucedo
Open Access Theses & Dissertations
BACKGROUND & AIM: Maintaining posture requires the input from three primary sensory systems. These systems include somatosensory, visual, and vestibular components. Of these three systems, the visual and vestibular systems work closest to maintain balance and posture due to visual-vestibular interactions that take place during static and dynamic activities. They are mainly responsible for identifying stimuli and using sensory information to orient the body in space. Thus, understanding how visual and vestibular components integrate may be critical to understand how visual and vestibular sensory information is weighted to control balance. The purpose of this investigation was to determine if visual …

The Control Of Amplitude And Direction In Bimanual Coordination, Zhujun Pan
LSU Doctoral Dissertations
Spatial coordination of bimanual movements is important when performing daily activities. Whereas, older adults and individuals with Parkinson’s disease (PD) commonly show difficulties in temporally coordinating the hands in bimanual coordination tasks, the effects of aging and Parkinson’s disease on the quality of spatial coordination between the hands are unclear. Thus, the present work investigated the impact of older age and PD on the spatial interference in a bimanual task in which 48 right hand-dominant participants (16 young adults, 16 older adults and 16 individuals with PD) drew simultaneously two lines with both hands with varied movement amplitudes (3 and …

The Anti-Inflammatory Effects Of Vitamin D And Exercise, Laura Ann Forney
LSU Doctoral Dissertations
Elevated inflammation is associated with several chronic diseases, including obesity. Exercise is an established effective treatment of this condition by decreasing adiposity and independently regulating inflammatory pathways. The potential for vitamin D to confer anti-inflammatory benefits has been explored in cell culture studies, but few have explored its action at the whole body level. PURPOSE: To investigate the relationship between inflammatory markers in trained and untrained individuals with vitamin D levels either above or below a suggested optimal concentration. METHODS: College-aged females (N = 63), both trained and untrained, reported to the lab four times: to assess body size and …

Administrator Perceptions Of Intramural Coed Flag Football Modifications: A Qualitative Analysis, Zacharias Wood
LSU Master's Theses
Coed sport environments can be paradoxical settings where pre-existing gender biases influence participants’ enjoyment and success. Furthermore, gendered messages and stereotypes as well as low expectations for females within coed sports can create participation barriers by reducing feelings of confidence and performance. Within Campus Recreation, intramural sport administrators have a significant role in determining participation opportunities and experiences. This investigation examined administrators’ perspectives about coed intramural flag football gender modifications. Specifically, three research questions guided this study: (a) how do intramural administrators view coed flag football gender modifications?; (b) to what extent do intramural administrators perceive gender modifications to impact …

Parental Pressure, Anxiety, And Performance Among Age Group Swimmers, Timothy Michael Dasinger
LSU Master's Theses
Background/Purpose: Parents introduce children to youth sport and can increase a child’s level of enjoyment in the sport. However, parents can also place too much pressure on the child, which can lead to increased pre-competition anxiety and decreased performance (Bois, Lalanne, & Delforge, 2008; Scanlan & Lewthwaite, 1984). The purpose of this study was to examine the relationships among perceived and desired parental pressure, pre-competition state anxiety, subsequent performance, and intention to continue the sport in youth swimmers ages 9-18. Method: A sample of 43 swimmers (17 male, 26 female; M=12.8±2.6 years) on a United States Swimming (USS) sanctioned club …

Can Gravitational Influences Explain Endpoint Precision Between Visual Conditions?, Chelsea Marie Soebbing
LSU Master's Theses
Reaches to remembered target locations often result in different endpoint precision when compared to reaches to actual (seen) targets. Interestingly, errors are observed whether the reach to the remembered location is performed in an environment with or without allocentric cues (visual cues from the environment) available. People tend to point below remembered target locations in the dark relative to normal room lighting while seated, standing, and reaching with a step. In this study we questioned the effect of gravitational influences on upper extremity reaching and pointing accuracy in dark and illuminated environments. We hypothesized that alterations in body orientation would …
Methionine Restriction-Induced Metabolic Changes In C57bl6j Mice,
2014
Louisiana State University and Agricultural and Mechanical College
Methionine Restriction-Induced Metabolic Changes In C57bl6j Mice, Cory Christopher Cortez
LSU Master's Theses
Introduction: Eighty percent restriction of normal dietary methionine (MR) intake has been shown to increase energy expenditure and attenuate the rate of adiposity gain in rodents, despite a paradoxical increase in energy intake. Energy expenditure in rats was shown to increase, even though physical activity level stays the same. This observation suggests that metabolic mechanisms account for the majority of increased energy expenditure measured in methionine restricted animals. Purpose: To observe and document the onset of physiological effects brought about and to determine the mechanistic role of the skeletal muscle on MR-induced metabolic changes in the C57BL6J mouse. Methods: C57BL6J …

The Effects Of Peripheral Nerve Impairments On Postural Control And Mobility Among People With Peripheral Neuropathy, Shuqi Zhang
LSU Doctoral Dissertations
Approximately 20 million Americans are suffering Peripheral Neuropathy (PN). It is estimated that the prevalence of all-cause PN is about 2.4% in the entire adult population, whereas over 8-10% in the population segment over the age of 55 (Martyn & Hughes, 1997). Peripheral Neuropathy leads to a high risk of falling, resulting from the deficits of postural control caused by the impaired peripheral nerves, especially the degenerative somatosensory system. To date, there is no effective medical treatment for the disease but pain managements. The deficits of postural control decrease the life quality of this population. The degeneration of peripheral nerves …

An Analysis Of A University Reclassification Effect On Applications Following A Move To A New Intercollegiate Athletic Association, Dylan P. Williams
LSU Doctoral Dissertations
Scholars have argued that athletics are utilized by universities to advertise their school to all individuals (Collins, 2012; Dwyer, Eddy, Havard, & Braa, 2010; Toma & Cross, 1998; Washington & Ventresca, 2004; Weaver, 2010). Expectedly, university officials are willing to contribute resources in order to develop an effective athletics program to establish an institution’s legitimacy among other universities (Collins, 2012; Toma & Cross, 1998; Washington & Ventresca, 2004). One tactic employed by schools focuses on the process of athletic association reclassification into the National Collegiate Athletic Association (NCAA) from other member associations (e.g., National Association for Intercollegiate Athletics). Officials consider …

Journal Articles
Non-human primate populations, other than responding appropriately to naturally occurring challenges, also need to cope with anthropogenic factors such as environmental pollution, resource depletion, and habitat destruction. Populations and individuals are likely to show considerable variations in food extraction abilities, with some populations and individuals more efficient than others at exploiting a set of resources. In this study, we examined among urban free-ranging bonnet macaques, Macaca radiata (a) local differences in food extraction abilities, (b) between-individual variation and within-individual consistency in problem-solving success and the underlying problem-solving characteristics, and (c) behavioral patterns associated with higher efficiency in food extraction. When …

INTRODUCTION: Energy drinks have become the soft drink of this millennium. They are commonly available everywhere including stores, schools and fitness centers. Yet, the effects of energy drinks, on metabolism at rest and during exercise, receive little attention. Ingredients in energy drinks such as caffeine and taurine are sympathetic stimulants and increase heart rate and blood pressure. However, it is unclear as to whether or not these effects actually improve exercise performance. Redbull is an example of an energy drink that is often consumed with the idea that it will improve performance during an exercise workout. PURPOSE The purpose of …
