A Counterbalanced Cross-Over Study Of The Effects Of Visual, Auditory And No Feedback On Performance Measures In A Simulated Cardiopulmonary Resuscitation, Carolyn Cason, Cynthia Trowbridge, Susan M. Baxley, Mark D. Ricard

Kinesiology Faculty Publications & Presentations - Archive

Background: Previous research has demonstrated that trained rescuers have difficulties achieving and maintaining the correct depth and rate of chest compressions during both in and out of hospital cardiopulmonary resuscitation (CPR). Feedback on rate and depth mitigate decline in performance quality but not completely with the residual performance decline attributed to rescuer fatigue. The purpose of this study was to examine the effects of feedback (none, auditory only and visual only) on the quality of CPR and rescuer fatigue. Methods: Fifteen female volunteers performed 10 minutes of 30:2 CPR in each of three feedback conditions: none, auditory only, and visual …

The Effects Of A 15 Week Exercise Intervention On Fitness And Postural Control In Older Adults, Forest Melton

Kinesiology Theses - Archive

Falls are the leading cause of nonfatal injuries in older adults, and often lead to adverse changes in confidence and lifestyle that trigger further declines in postural control. Decreased fitness is associated with poor performance on postural control assessments, especially those that increase task difficulty. The purpose of this study was to analyze the impact of a traditional Group Fitness class and a Wii Fitness exercise program on individual's ability to maintain postural control, with an environmental distracter. 87 community dwelling seniors were randomized into 1 of 3 groups (Control, Wii Fitness, Group Fitness). Interventions were delivered 3 times per …

The Relationships Between Optimism And Pessimism And Burnout In Youth Soccer Players, Brandy A. Rentz

College of Graduate Studies: Theses & Dissertations

Sport related burnout has become a concern for many athletes, coaches, and sport psychologists. Although burnout in sport is receiving more attention, the research still remains relatively limited (Capel, 1986; Dale & Weinberg, 1990; Fender, 1989; Gould, Udry, Tuffey, & Loehr, 1996). Dale and Weinberg (1990) indicated a need for future research concerning the identification of characteristics that may predispose athletes to burnout. No past research was found that investigated the relationship between optimism/pessimism and sport burnout. The primary purpose of this investigation was to examine the relationships between optimism and pessimism with burnout. A secondary purpose was to determine …

Examining The Perceptions Of Teachers' Efficacy In Handling Student Misbehavior (Tehsm) In Classroom And Physical Education Settings, Costas Nicou Tsouloupas

LSU Doctoral Dissertations

Research has found dealing with student misbehavior as the most prominent source associated with teachers’ negative behavioral outcomes at work. One approach for understanding teachers’ behavioral responses to student misbehavior is through the efficacy beliefs of teachers. This line of inquiry has lead to the advancement of the concept of teacher efficacy in handling student misbehavior or TEHSM. TEHSM was found to significantly and negatively mediate the relationship between teachers’ perception of student misbehavior, emotional exhaustion, and turnover intentions respectively. To date, limited information is available regarding the makeup of TEHSM which gives emphasis to the significance of this dissertation. …

The Association Between Different Clinical Methods For Evaluating Lower Extremity Muscular Function, Roger Olen Kollock Jr.

Human Movement Studies & Special Education Theses & Dissertations

Insufficient muscular strength at the hip and thigh may increase an athlete's susceptibility to lower extremity injuries. In an attempt to reduce this risk, researchers have proposed lower limb strength testing within preparticipation physical examinations (PPE) and return-to-play (RTP) evaluations. However, because of cost, mobility, and or set-up time, some methods are not feasible in certain settings. Since methodological approaches between methods can vary, having different contraction modes and testing parameters, substitution of one method for another may not be valid. Therefore, the purpose of this study is three-fold: a) to determine the association between isometric and isokinetic contraction modes …

A Multi-Species Analysis Of Biomechanical Responses Of The Head To A Shock Wave, Richard Bolander

Wayne State University Dissertations

Shock wave induced brain injury remains a field of research that has great consequences for the rehabilitation of soldiers and civilians that are exposed to an explosion. As such, for the research to be successful in developing strategies to mitigate the effects of these injuries, appropriate research methods need to be developed. Animal models are currently employed to understand the brain's response to a shock wave exposure. Unfortunately no criteria have been established that indicates in what way the mechanical inputs that the cells in an animal's brain are subjected to are similar to a human. The purpose of this …

Computational Simulation Of Skull Fracture Patterns In Pediatric Subjects Using A Porcine Model, Christina Devito Wagner

Wayne State University Dissertations

In cases of suspected child abuse with skeletal trauma, it is often the role of the injury biomechanist, forensic pathologist, clinical radiologist, and forensic anthropologist to determine the mechanism of injury when the child victims cannot speak for themselves. This is a challenging task, especially for the head, as comprehensive biomechanical data on skull fracture in infants and children do not currently exist, and frequently the determination regarding cause of injury is based on anecdotal evidence from the medical literature and unsubstantiated eyewitness accounts. The current process may result in unreliable autopsy interpretation and miscarriages of justice due to a …

Psychosocial Aspects Of Physical Activity And Fitness In Special-Population, Minority Middle School Children, Jeffrey J. Martin, Nate Mccaughtry, Anne S. Murphy, Sara Flory, Kimberlydawn Wisdom

Kinesiology, Health and Sport Studies

Special-population research predicting physical activity (PA) and fitness with minority middle school children from at-risk environments is rare. Hence, the purpose of our investigation was to evaluate the ability of important social cognitive and environment-based measures to predict PA and fitness with children with developmental delay, cognitive, and emotional impairments. Children (N = 89, ages 11-15) completed questionnaires assessing social cognitive and environment-based constructs, self report PA, and completed fitness testing. Correlational results supported some hypotheses. The descriptive and correlational results also indicated commonalities with similar research on non special-population minority middle school children from at-risk environments.

Walking Abnormalities Are Associated With Copd: An Investigation Of The Nhanes Iii Dataset, Jenna M. Yentes, Harlan Sayles, Jane Meza, David M. Mannino, Stephen I. Rennard, Nikolaos Stergiou

Journal Articles

Research on the peripheral effects of COPD has focused on physiological and structural changes. However, different from muscular weakness or decreased physical activity, mechanical abnormalities of the muscular system, e.g. walking, have yet to be investigated. Our purpose was to utilize the National Health and Nutritional Examination Survey (NHANES) dataset to determine whether walking abnormalities are associated with COPD severity. To determine if walking abnormalities were independently associated with COPD severity, our analysis aimed to investigate the association of physical activity levels with COPD severity and with walking abnormalities. The NHANES III dataset that contains data for 31,000 persons that …

This study evaluated the effects of elliptical exercise on fatigue and QOL reports in patients with MS. Patients with MS (n = 26) completed the Fatigue Severity Scale (FSS), the Modified Fatigue Impact Scale (MFIS), and the Medical Outcomes Study 36-Item Short Form Health Survey (SF-36) before and after completing 15 elliptical exercise training sessions. Changes in fatigue and QOL were assessed based on any changes in the fatigue and SF-36 questionnaires, and correlations between changes in each of the …

The Role Of Motivation And Physical Activity In A Weight Loss Program, Ellen Kane Stevens

LSU Master's Theses

Every year thousands of overweight and obese people in the United States join weight loss programs such as Weight Watchers in an effort to become healthier and feel more attractive. Weight Watchers has increased its program focus on physical activity as a critical part of weight loss. Initiating a consistent physical activity routine, however, is generally one of the last behavior changes made by program members, despite its proven role in weight loss maintenance. Using self-determination theory as a framework, the purpose of this study was to examine how perceptions of fulfillment of three psychological needs (i.e. competence, autonomy, and …

Cross-Validation Of A Recently Published Equation Predicting Energy Expenditure To Run Or Walk A Mile In Normal Weight And Overweight Adults, Cody Edward Morris

Electronic Theses and Dissertations

An equation recently published by Loftin, et al. (2010) was cross-validated using 30 subjects consisting of 10 normal weight walkers, 10 overweight walkers, and 10 distance runners. Gender was balanced across sub-groups. Participants walked or ran for 5 minutes at their preferred pace. Preferred walking pace was determined by six timed 50-ft trials and preferred running pace by the runner's typical training pace. Energy expenditure (EE) was determined via indirect calorimetry and reported in absolute units (kcal), and corrected to a mile distance. Body composition was assessed via DXA. EE per mile was predicted using the Loftin, et al. (2010) …

The Effect Of A Physical Education Games Unit On Children’S Participation In Neighborhood Physical Activity, Beth Erin Eddy

University of Kentucky Master's Theses

Many strategies to increase children’s physical activity have been studied, noted and implemented. It is important that physical educators realize their role in increasing physical activity both in school and outside of school. In order to promote physical activity outside of school it is important to understand what types of physical activities in which children enjoy participating. This study manipulated specific games taught in physical education classes and then explored how many and what types of these activities were continued in out-of-school free play at home in the children’s neighborhood. The students’ activities increased after the intervention, especially the activities …

Effects Of Lateral Ligament Sectioning On The Stability Of The Ankle And Subtalar Joint, Stacie I. Ringleb, Ajaya Dhakal, Claude D. Anderson, Sebastian Bawab, Rajesh Paranjape

Mechanical & Aerospace Engineering Faculty Publications

Patients with subtalar joint instability are often diagnosed with ankle instability. Only after a prolonged period of time in which a patient does not improve after treatment for ankle instability is subtalar joint instability considered. To develop a clinically relevant method to diagnose subtalar joint instability, the kinematics of the simulated unstable subtalar joint were examined. A 6 degree-of-freedom positioning and loading device was developed. Plantarflexion/dorsiflexion, inversion/eversion, and internal/external rotation were applied individually or as coupled motions along with an anterior/posterior drawer. Kinematic data were collected from sensors attached to the calcaneus, talus, and tibia by keeping all the ligaments …

Physical Activity And Health-Related Quality Of Life Among Elementary Students: An Integrated Perspective, Xiangli Gu

LSU Doctoral Dissertations

School physical education (PE) not only offers and promotes health-related physical activity, but also encompasses the promotion and development of perceptions of mental health (USDHHS, 2010). It has been suggested that health-related quality of life (HRQOL) can predict future health, monitor children’s psychosocial health, and identify those most at risk or in need of support at an early stage. Assessing physical activity (PA) and health-related quality of life have become major issues in pediatric public health and also serve as a major goal of Health people 2020 (USDHHS, 2010). Research including assessment of theory-based mediators of health-related outcomes is needed …

Assessment Of Core Stability: Developing Practical Models, Andy Waldhelm

LSU Doctoral Dissertations

Core stability is a concept in the health and fitness professions which became popular in the early 1990s. Despite its popularity, core stability remains a generalized term, which is poorly understood and lacks a universal definition and gold standard assessment. This makes it difficult to identify the role of core stability in athletic injury prevention and performance. To better assess core stability, the objective for this dissertation was to construct a reliable core stability index using measurements which best define and evaluate core stability. The purpose of our first experiment was to introduce and determine the intra-tester reliability of clinical …

Exercise and Sport Studies: Faculty Publications

As part of the insulin signalling pathway, Akt influences growth and metabolism. The AKT1 gene G205T (rs1130214) polymorphism has potential functional effects. Thus, we determined whether the G205T polymorphism influences metabolic variables and their responses to aerobic exercise training. Following dietary stabilization, healthy, sedentary, 50- to 75-year-old Caucasian men (n= 51) and women (n= 58) underwent 6 months of aerobic exercise training. Before and after completing the intervention, dual-energy X-ray absorptiometry was used to measure percentage body fat, computed tomography to measure visceral and subcutaneous fat, and oral glucose tolerance testing to measure glucose total area under the curve (AUC), …

Effect Of An Injury Prevention Training Program On Risk Factors Associated With Acl Injury, Daniel Medrano

Open Access Theses & Dissertations

Increased involvement in women's sports has been met with a disproportionate incidence of anterior cruciate ligament (ACL) injuries. The underlying cause of ACL injury is likely multi-factorial, with risk factors including deficits in lower extremity kinematics, kinetics, muscle activity, strength, stability, and sensitivity. Insight into risk factors has prompted several injury prevention programs. However, program outcomes have been mixed. Therefore, the purpose of this study was to examine the effect of specialized training on risk factors theorized to increase the incidence of ACL injury.

Fifty-six (28 control, 28 intervention) apparently healthy females volunteered to participate in this study. Training was …

Isometric Neck Strength In Concussed And Non-Concussed High School Football Players, Cameron Layne Raschke

Open Access Theses & Dissertations

Football accounts for a significant portion of the 1.275 million concussions per year. Neck strength has been theorized to possibly assist in the attenuation of severe impacts and possibly prevent football-related concussions. The purpose of this study was to investigate potential differences in isometric neck strength in flexion, extension, and lateral flexion right/left between concussed high school football players and matched non-concussed football players. Sixteen high school players that suffered a football-related concussion during the 2010 competition season comprised the research group, and were later matched to a player that did not suffer a concussion, on the basis of age, …

The Effects Of Tai Chi On Balance And Peripheral Somatosensation In Older Adults With Type 2 Diabetes, Elisabeth Inge Cavegn

Open Access Theses & Dissertations

The increasing prevalence of type 2 diabetes in older adults is a major health concern, as older adults with diabetes have a two- to threefold risk of injurious falls and physical disability. Although studies on the effects of Tai Chi on balance and fall prevention have increased over the last two decades, the benefits for older adults with diabetes, specifically for those with impaired somatosensation in the lower extremities, are limited. Therefore, the purpose of this study was to investigate the effects of Tai Chi exercise on balance, peripheral somatosensation, and fitness in older adults with type 2 diabetes. The …

Advisor: John Cavanaugh, MD

Major: Biomedical Engineering

Degree: Doctor of Philosophy

The estimated yearly cost of lost-time work injuries and illnesses is $140 billion. The average cost of musculoskeletal disorders (MSDs) exceeds all other claims. These injuries persist in spite of ergonomic interventions addressing known risk factors. Work/rest ratios have not received a significant amount of attention, particularly in low back disorders, and it is hypothesized that the lack of adequate rest within a work cycle may contribute to muscle fatigue …

Secondary Physical Educators' Content Negotiations, Matthew Daniel Ferry

Wayne State University Dissertations

In light of growing concern over the relation between physical inactivity and a variety of biomedical and psychosocial conditions and the disjuncture between larger physical activity culture and secondary school physical education curriculum, the purpose of this study was to examine how middle school physical education teachers negotiated content and curricular decisions. A variety of theories guided this study, including Bourdieu's theories of habitus and field (1977), teacher socialization theory (Lawson, 1983; 1988), teacher ideology (Apple, 2004), teacher emotion (Hargreaves, 1998; McCaughtry, 2004), curriculum as a political text (Pinar, Reynolds, Slattery, & Taubman, 2004), and range of critical and post-structural …
