Twenty-five adults with clinicallyâ??confirmed MS were enrolled in this study to undergo the 8-week intervention on a side-alternating vibration machine. The training was delivered three times a week for eight weeks a …

Class-Related Emotions In Physical Education: A Control-Value Theory Approach, Kelly L. Simonton

LSU Master's Theses

This study investigated a model of students’ control beliefs and task value in physical education (PE). Specifically, it examined relationships among students’ perceptions of their teachers’ communication and instructional clarity, control beliefs and values toward PE, and academic emotions. High school students (N= 529) completed valid and reliable instruments assessing perceptions of teacher characteristics, control, value, enjoyment, and boredom in PE. Descriptive statistics, bivariate correlations, and internal reliability estimates were calculated. A path analysis was used to test the hypothesis that teacher communication and clarity would be related to control-value appraisals which would in turn, positively predict enjoyment or boredom. …

Testing Fitness-Related Phone Application Technology In Physical Activity Classes, Angela Nicole Simonton

LSU Master's Theses

Many young adults are inactive (Centers for Disease Control and Prevention, 2010) and time spent on smartphones and applications (“apps”) is high (Pew Research Center, 2014; The Nielsen Company, 2014). Technology is often viewed as a barrier to health behavior, so seeking ways of using technology to facilitate physical activity (PA) and other health-related behaviors could be beneficial. The Social Cognitive Theory (SCT) framework was used to determine if the NexTrack smartphone app could increase PA behaviors and SCT-related constructs among university students in PA courses. Participants in the NexTrack app intervention group were hypothesized to report increased psychosocial and …

Neural Recovery Rates Of Knee Extensors Following A Resistance Exercise Protocol, Darren Michael Polk

LSU Master's Theses

Fatigue can manifest in the human body in a multitude of ways, one of these is neural-based fatigue. Neural-based fatigue occurs when the nerve fails to activate a muscle (Brooks et al., 2005). The purpose of this research is to investigate rates of neural recovery following a resistance exercise protocol. A pre-test consisting of a 5-second maximum voluntary isometric knee extension was performed. Next, each subject performed a resistance exercise protocol consisting of 5 sets of 10 repetitions of isokinetic knee extensions. Post-tests following the resistance exercise protocol consisted of 5-second maximum voluntary isometric knee extensions after 1, 5, 10, …

An Investigation Of The Generalizability Of Buoyancy From Academics To Athletics, Jackie Rae Victoriano

LSU Master's Theses

Buoyancy, the ability of an individual to handle everyday setbacks, has been applied successfully to academics, and has implications for performance and well-being. The purpose of this investigation was to determine if the concept of buoyancy can be successfully applied to the domain of sports (i.e., athletic buoyancy). This study sought to examine the relationship between academic and athletic buoyancy, as well as the efficacy of five sport-oriented predictors (5Cs), confidence, coordination (planning), commitment, composure (anxiety), and control, on both athletic and academic buoyancy. Sport club athletes (N = 285) aged 18 to 31 years completed a one-time survey assessing …

Relationship Between Metabolic By-Products And Nervous System Failure/Fatigue, Tyler Mitchell Farney

LSU Doctoral Dissertations

Fatigue has generally been defined as an acute impairment of exercise/sport performance that includes both an increase in the perceived effort necessary to exert a desired force or power output, and the inability to produce the desired force or power output. The majority of research to date looking at fatigue has focused upon substrate utilization, however, what is relatively unknown is the contribution the nervous system has upon fatigue. Therefore, the purpose of this dissertation was to investigate potential mechanisms that relate to neural fatigue. An additional purpose was to determine if there were any relationships between metabolic by-products and …

An Ideal-Type Through Innovation Diffusion: Recording The Construction History Of Football Stadiums In The National Collegiate Athletic Association Division I Football Bowl Subdivision (Fbs), Patrick Michael Tutka

LSU Doctoral Dissertations

Dr. John Bale (1984) argued sport scholars need to examine whether innovation diffusion occurred in sport. Rogers (1962, 2003) argued innovation diffusion process involves the following: 1) an innovation; 2) an available communication system(s); and occurs 3) over time; and 4) among members of a social system (p. 11). This project also adds geography as suggested by Bale (1984) and Hagerstrand (1952, 1953) to the study of innovation diffusion. The purpose of the current project is to examine whether innovation diffusion exists within the strong social system of college football. The study involves the collection of data on college football …

A series of three studies were conducted to gain insight to various influences on cardiovascular and autonomic function. The first study examined the influence of exercise training of brachial artery flow-mediated dilation (BAFMD) using meta-analytic techniques. Sixty-six studies included in the analysis demonstrated exercise training improves BAFMD compared to controls. Results indicated exercise training significantly alters …

How Do Social Norms Affect Physical Activity And Performance On An Endurance Task?, Keith David Randazzo

LSU Doctoral Dissertations

Despite the extensive benefits associated with a physically active life style, less than 50% of US adults engage in recommended levels of physical activity (PA), so finding ways to structure environments to promote PA is an important concern. Social norms, conceptualized as an individual’s perception of peer behavior, provide a framework for exploring factors that influence decisions to be physically active. Although researchers have investigated how social norms influence a variety of behaviors, the PA domain has not been fully explored. The focus of this dissertation is to apply social norms theories to investigate how normative information influences PA intentions …

An Exploratory Approach To Manipulating Dynamic Stability: Investigating The Role Of Visual Control During A Precision Foot Placement Task, Russell Cg Kennedy

Theses and Dissertations (Comprehensive)

ABSTRACT

Background: The visual system provides the body with an accurate sensory system; designed to gather information at a distance and acts as a feedforward control mechanism during human locomotion. By doing so, visual information contributes coordination of the head-arm-trunk (HAT) segment and modulating foot placement. The purpose of this study was to examine the effects of a constrained pathway during a complex navigational stone-stepping task on HAT segment control and how the visual system guides locomotion during a complex foot placement task.

Methods: Nine university-aged females (Mean age: 22.5 years old +/-1.75) participated in this study. Participants …

The Effects Of External Focus Of Attention Exercise Rehabilitation On Dual Task Walking In Parkinson's Disease, Eric N. Beck

Theses and Dissertations (Comprehensive)

Parkinson’s disease impairs control of well-learned movements, and therefore, individuals with Parkinson’s disease are forced to walk with greater conscious control. This causes difficulties while walking and completing a secondary task simultaneously (dual tasking), in that distractions from conscious control of walking increase the risk of falls and injury. Although, attention-based exercise may be a potential avenue to decrease the demands associated with walking in Parkinson’s disease. For example, an external focus of attention (on manipulated objects) has been found to recruit the networks that are important for walking with little conscious control (automatic control networks). In contrast, an internal …

The Effects Of A Low Back Pain Vibration Modality On Trunk Postural Control, Adam R. Cornwall

Theses and Dissertations (Comprehensive)

Abstract

Introduction: Low back pain (LBP) is prevalent worldwide and is affecting even more individuals as the population ages. There has recently been an increase in production of low back pain (LBP) vibration modality belts that apply localized vibration to the lumbar region of the spine as it has shown to reduce pain. However, vibration is also known to perturb muscle spindles and thus interfere with proprioception. If a LBP vibration modality causes a proprioceptive deficit in the trunk lumbar region it could potentially increase an individual’s risk of injury due to poor postural control. Therefore, the effects of a …

The Effects Of Manipulated Somatosensory Input On Simulated Falls During Walking, Sarah Mitchell-Ewart

Theses and Dissertations (Comprehensive)

Previous research has demonstrated that there is a distinct relationship between aging and instability. The somatosensory system plays a significant role in balance control in conjunction with vision and the vestibular system (Qiu et al., 2012). Evidence has shown that manipulation of the mechanoreceptors on the plantar surface of the foot has a direct effect on balance control. By manipulating these receptors with hypothermic anesthesia and vibration, researchers are capable of simulating the effect of sensory modification on healthy individuals, in order to understand the role that plantar-surface sensation has in adapting to perturbation during gait (Perry et al., 2001; …

The 2d:4d Ratio, Handedness, And Sex Across The Age Span, Helen A M Protopapas Ms.

Theses and Dissertations (Comprehensive)

The ratio of the difference between the 2nd and 4th digits of the hand (2D:4D ratio) has been demonstrated to be an indirect indicator of prenatal testosterone levels. Prenatal testosterone has been found to play a role in brain development in utero, and thus may influence lateral asymmetries, such as handedness. Consequently, one of the aims of the current study was to examine relationships between the 2D:4D ratio, hand preference, and hand performance with the factors of sex (males and females), handedness (right handers and left handers), and age considered. A total of 104 participants were tested, 90 right handers …

The Influence Of Hip Mobility And Fatigue On Spinal Flexion And Muscle Activation In Rugby Scrum Performance, Joshua D. Clayton

Theses and Dissertations (Comprehensive)

Introduction: Rugby scrumming is a means of restarting play following a minor rule infringement that can occur up to 28 times per game. The scrum poses a significant injury risk, with more days missed due to injury per event than any other rugby activity. Rugby players also have a significantly higher rate of spine injury than the general population, perhaps due to flexion in combination with high compression forces, which has been cited as the main mechanism of injury. Flexion of the spine has also been associated with poor hip mobility and quadriceps fatigue in other athletic tasks and may …

Online Learning And The Effects On Functional Health: A Pilot Study, Jessica Mangis

EWU Masters Thesis Collection

"Online learning presents a major risk on our emotional and physical health, otherwise known as functional health which results in a trend away from active leisure pursuits and recreational sports and leading us towards a sedentary lifestyle (Wang, Luo, Gao, & Kong, 2012). Sedentary behavior leads to many health risks and conditions such as cardiovascular disease, one of the leading causes of death. A sedentary lifestyle is defined as someone who does not meet the minimum suggested levels of physical activity: 150 minutes of endurance training and two days of strength training a week (American College of Sports Medicine, 2011; …
