Biomechanical Difference Between Chronic Ankle Instability Individuals And Healthy Individuals During Landing On Flat, Inverted And Combined Surfaces, Xuan Liu

Masters Theses

Lateral ankle sprains most frequently occurs during sports. Individuals who experienced a first time ankle sprain had a high reoccurrence rate and residual symptoms and functional instability leading to chronic ankle instability (CAI). The purpose of this study was to investigate kinematic and kinetic differences between CAI individuals and healthy subjects in single-leg drop landing on a flat surface, an inverted surface and a combined surface of inversion and plantarflexion. A total of 17 subjects (6 subjects with chronic ankle instability, 11 healthy subjects) performed five trails in each of four dynamic movement conditions of drop landing from a height …

Knee Biomechanics Of Older Adults During Common Recreational And Daily Activities, Julie Lynn Pfeiffer

Masters Theses

Among older adults, socialization is a key motivating factor for participation in physical activity. In order to develop evidence-based physical activity recommendations for older adults with knee pathologies a better understanding of knee biomechanics during social recreational activities is needed. The purpose of this study was to determine knee joint kinematics and kinetics in healthy older adults during golf and bowling. Knee biomechanics during these recreational activities were also compared to those experienced during activities of daily living. Motion analysis data were collected as subjects performed walking, stair ascent, stair descent, and either golf or bowling. Knee angles, peak knee …

Mechanism Of Lpa-Induced Lipid Uptake In Macrophages, Kan Xu

Masters Theses

Cardiovascular disease, currently the leading cause of mortality throughout the developed countries, is mainly caused by atherosclerosis, which is recognized as a chronic inflammatory disease. Atherosclerotic plaques are characterized by accumulations of lipid in arterial walls together with infiltration of macrophages. These macrophages differentiate from monocytes which transform into foam cells through phagocytizing various forms of lipid, are believed to be the main component of early atherosclerotic lesions.

Lysophosphatidic acid (LPA), a potent bioactive lipid, regulates a broad range of cellular functions in various cell types. In our findings, LPA-induced macrophages may enhance the lipid uptake effect in both J774A.1-mouse …

Staphylococcus Pseudintermedius: Population Genetics And Antimicrobial Resistance, Ricardo Videla

Masters Theses

Staphylococcus pseudintermedius is a Gram-positive coagulase-negative coccus. It is a normal inhabitant of the skin of dogs. However, clinical disease can be observed in animals that are immunossuppressed or if the skin barrier is altered. This bacterium is recognized as the main cause of canine pyoderma and has also been associated with other conditions such as infection of the urinary tract, the ears, and surgical wounds.

Methicillin resistance and resistance to other antimicrobials regularly used by veterinarians is common among S. pseudintermedius which can complicate treatment. The first report of mecA, gene responsible for methicillin resistance, in S. pseudintermedius …

Use Of A Novel Parental Engagement Tool In An After-School Obesity Prevention Program, Lindsay Schloesser Miesel

Masters Theses

Objective: To assess the impact of parental health messages delivered via two avenues on children’s reported food/drink exposure and child/parent goal setting.

Design: Pre- and post-test quasi-experimental design with two treatment groups and one historical control group.

Setting: Two elementary schools in East Tennessee.

Participants: Seventy-seven parents of participating fourth and fifth graders.

Methods: Messages were delivered to parents as the home component of an after-school program via digital home message centers (digital message group) or a more traditional method using a web-based platform and/or handouts of messages (traditional enhanced group) with results compared to a historical control with …

Ncaa Division I Athletic Trainers' Perceptions And Use Of Psychological Skills During Injury Rehabilitation, Mary Kathleen Estepp

Masters Theses

Applied sport psychology research suggests that the use of psychological skills (e.g., positive self-talk, goal-setting, relaxation) during the rehabilitation process increase recovery rates, increase adherence to rehabilitation, and decrease anxiety and stress (Heaney, 2006). Certified athletic trainers (ATCs) hold a critical role within injury rehabilitation as the primary health care professional who interacts with injured athletes. Therefore, properly trained, ATCs have been identified as the ideal professional to implement psychological skills during injury rehabilitation (Larson, Starkey, & Zaichkowsky, 1996). The purpose of this study was to explore National Collegiate Athletic Association (NCAA) Division I (D-I) ATCs use of psychological skills …

Do Weight Status And The Level Of Dietary Restraint Moderate The Relationship Between Package Unit Size And Food Intake?, Chrystal Louisa Haire

Masters Theses

Background: Package unit size may influence consumption. Single-serving (SS) packages, as compared to larger, standard (ST) packages, may increase awareness of what a standard serving is and assist in reducing consumption. Individuals who may be concerned about the amount they consume, such as overweight (OW) and dietary restrained individuals, may be more influenced by SS packages. Thus, the purpose of this study was to examine if weight and dietary restraint status moderate the influence of package size on consumption. It was hypothesized that SS packages would help to reduce intake in OW and/or restrained individuals as compared to normal weight …
