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 …

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), …

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 …

LONGISSIMUS MUSCLE FATIGUE AND INJURY RESPONSE DUE TO ELECTRICAL STIMULATION WITH VARIED WORK/REST RATIOS

BY

PETER WAWROW

May 2011

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 …

Outdoor Recreation Participation Of Pennsylvanians With Disabilities, Elizabeth H. Weybright, Alan R. Graefe, Andrew J. Mowen, Nate E. Trauntvein

Kinesiology and Health Science Faculty Publications

Approximately 16% of United States residents report having some sort of physical disability that limits their recreation participation. Many of these individuals may have an abundance of free time due to unemployment, part-time work status, or retirement, and therefore recreation and leisure have the potential to provide great meaning in their lives. Qualitative and quantitative data from a State Comprehensive Outdoor Recreation Plan was used to better understand the outdoor recreation habits and perceptions of Pennsylvania residents with disabilities. Using descriptive, chi square, and ANOVA statistics, results indicate that these individuals perceive fewer benefits from outdoor activities, experience different types …

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 …

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 …

Electromechanical Delay Of The Knee Flexor Muscles After Harvesting The Hamstrings For Anterior Cruciate Ligament Reconstruction, Stavros Ristanis, Elias Tsepis, Dimitrios Giotis, Franceska Zampeli, Nikolaos Stergiou, Anastasios D. Georgoulis

Journal Articles

Objective: To investigate if harvesting of semitendinosus (ST) and gracilis for anterior cruciate ligament (ACL) reconstruction will have an effect in coordinative firing pattern of the hamstrings under fatigue. We hypothesized that fatigue will increase the electromechanical delay (EMD) of the hamstrings on the harvested site and impair the synchronization between the medial and lateral hamstrings, in terms of muscle activity onsets.

Design: Prospective nonrandomized study. Setting: Institutional. Patients: Twelve ACL reconstructed patients with hamstrings, 2 years postoperatively.

Interventions: The patients performed a fatigue protocol with 25 continuous maximal isometric voluntary contractions of 8-second duration with 2-second …
