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 …

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, …

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

Electronic Theses and 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 …

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 …

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 …

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 …

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 …
