Finite Element Reconstruction Of Real World Aortic Injury In Near-Side Lateral Automotive Crashes With Conceptual Countermeasures, Aditya Neelakanta Belwadi

Wayne State University Dissertations

Traumatic rupture of the aorta (TRA) remains the second most common cause of death associated with motor vehicle crashes after brain injury. On an average, nearly 8,000 people die annually in the United States due to blunt injury to the aorta. It is observed that more than 80% of occupants who suffer an aortic injury die at the scene due to exsanguination into the chest. With the advent of more accurate and established human body finite element (FE) models, FE crash reconstruction methods may become a valuable tool when assessing crash scenarios and occupant injury mechanisms.

The current study is …

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 …

Kinesiology Theses - Archive

The purpose of this study was to determine physical activity levels in students enrolled in a walk/jog class that was delivered online and in a traditional face to face environment. Differences in voluntary exercise intensity and duration between the two delivery modes were examined as they specifically related to fulfilling the course requirements. Overall activity levels were determined for a 7 day period. Forty-three college students [mean (±SD) age: 24.7 ± 8.2 years; height: 65.7 ± 3.5 in; weight: 73.5 ± 17 kg] enrolled in a walk for fitness or walk for fitness class at the university level volunteered for …

The Effect Of Joint Mobilization On Functional Outcomes Associated With Chronic Ankle Instability, Matthew C. Hoch

University of Kentucky Doctoral Dissertations

Ankle sprains are among the most common injuries sustained by physically active individuals. Although ankle sprains are often considered innocuous in nature, a large percentage of individuals experience repetitive sprains, residual symptoms, and recurrent ankle instability following a single acute sprain; otherwise known as chronic ankle instability (CAI). In addition to repetitive ankle trauma, those with CAI experience reductions in functional capacity over the life span. This indicates that current intervention strategies for CAI are inadequate and require further investigation.

The objective of this dissertation was to explore differences in walking and running gait parameters between individuals with and without …

Cognitive Interference From Food Cues In Weight Loss Maintainers, Normal Weight, And Obese Individuals, Suzanne Phelan, Jason Hassenstab, Jeanne M. Mccaffery, Lawrence Sweet, Hollie A. Raynor, Ronald A. Cohen, Rena R. Wing

Kinesiology and Public Health

Much attention has been paid to the behavioral characteristics of successful weight loss maintenance, but less is known about the cognitive processes that underlie this process. The purpose of this study was to investigate cognitive interference from food-related cues in long-term weight loss maintainers (WLM; N = 15) as compared with normal weight (NW; N = 19) and obese (OB; N = 14) controls. A Food Stroop paradigm was used to determine whether successful WLM differed from controls in both the speed and accuracy of color naming words for low-calorie and high-calorie foods. A significant group × condition interaction for …

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.

Elliptical Exercise Improves Fatigue Ratings And Quality Of Life In Patients With Multiple Sclerosis, Jessie M. Huisinga, Mary Filipi, Nikolaos Stergiou

Journal Articles

Fatigue, reduced quality of life (QOL), and lower physical activity levels are commonly reported in patients with multiple sclerosis (MS). 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 …

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 …

Anterior-Posterior And Medial-Lateral Control Of Sway In Infants During Sitting Acquisition Does Not Become Adult-Like, Fabien Cignetti, Anastasia Kyvelidou, Regina T. Harbourne, Nikolaos Stergiou

Journal Articles

We examined (1) how sitting postural control in infants develops in the anterior–posterior (A/P) and medial–lateral (M/L) directions of sway, and (2) whether this control is already adult-like during the late phase of infant's sitting acquisition. COP data were acquired from 14 healthy infants (from the onset of sitting until independent sitting) and 21 healthy adults while sitting on a force platform. Attractor dimensionality (CoD: correlation dimension), attractor predictability (LyE: largest Lyapunov exponent), and sway variability (RMS: root-mean square) were calculated from the COP data to evaluate postural control. In the A/P direction, sitting was mastered by the infants by …

Advances in powerlifting equipment have enabled athletes in that sport to achieve lifts once thought impossible. The effect of training using specialized powerlifting gear on performance has not yet been studied. PURPOSE: To examine the effects of powerlifting equipment on performance measures before and after 10 weeks of training. It was hypothesized that equipped lifters would achieve higher total training volumes and greater performance gains in the squat, bench press, and deadlift. METHODS: Eighteen powerlifters between the ages of 18 and 26 were randomized into either a group that trained and competed in equipment (Eq), or trained and competed without …

Akt1 G205t Genotype Influences Obesity-Related Metabolic Phenotypes And Their Responses To Aerobic Exercise Training In Older Caucasians, Jennifer A. Mckenzie, Sarah Witkowski, Andrew T. Ludlow, Stephen M. Roth, James M. Hagberg

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), …

Seventeen female NCAA Division I collegiate soccer players (age 19.7 +1.0 years, height 166.1 +6.4 cm, weight 64.2 +8.2 kg) completed a graded exercise test to determine maximal oxygen consumption (VO₂max). Participants were placed into a kettlebell intervention (KB) group (n = 9) or a circuit weight training control (CWT) group (n = 8). Participants in the KB group completed a kettlebell snatch test to determine individual snatch repetitions. Both groups trained 3 days per week for 4 weeks in …

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 …
