Qtc Is Associated With Obesity And Physical Activity Level For African American Females, C. Jayne Brahler

Health and Sport Science Faculty Publications

Long QT syndrome (LQTS) is an independent risk factor for cardiovascular or ischemic disease mortality. Obesity as a cause for acquired LQTS in otherwise healthy individuals is rapidly gaining the attention of the scientific community. African American people have a higher incidence of obesity compared to Caucasians, yet race-specific information is not available for their prevalence of LQTS. Chronic physical activity can help reduce the incidence of obesity, yet little is known about the effects of chronic physical activity on acquired LQTS. Subjects in this study were a volunteer sample of African American mothers (21-53 yr, n = 44) and …

Chronic Hypoxia, Exercise Training, And Skeletal Muscle Capillarity: Angiogenic Regulation And Morphological Consequences, Ivan Mark Olfert

Loma Linda University Electronic Theses, Dissertations & Projects

Angiogenesis is important in health and disease. In particular, exercise training is known to increase skeletal muscle capillarity, providing there is sufficient training intensity. The stimulus for this may be intracellular hypoxia activating angiogenic growth factor gene expression. Acute hypoxia alone has been shown to increase the gene expression of several key angiogenic regulators, e.g. vascular endothelial growth factor (VEGF) and to a lesser degree transforming growth factor-β1 (TGF-β1), basic fibroblast growth factor (bFGF), and thrombospondin-1 (TSP-1), an endogenous negative angiogenic regulator. Paradoxically, however, chronic hypoxia is generally not found to increase mammalian skeletal muscle capillarity. Accordingly, we hypothesized that …

Injuries to the ankle joint are among the most common of all sport-related injuries. Figures range from 10% to 30% of all injuries and from 5% to 20% of all time-loss injuries.1-9 Athletes participating in sports such as football, soccer, basketball, and volleyball are especially at risk for this type of injury, largely because of the running and jumping involved. In 1977, Garrick3 reported that during any single year of a 6-year period at the University of Washington, at least 16% of all time-loss injuries for all sports involved ankle sprains.

Is There A Difference In Cortical Representation Between Dominant And Non-Dominant Arm Muscles Of Elite Badminton Players?, Dylan J. Edwards

Theses : Honours

Training for sport involves the development of skill and coordination. The physiological changes associated with skill acquisition are complex and at present poorly understood. One of the areas in the central nervous system thought to be involved with skill acquisition is the cerebral motor cortex where localised areas are responsible for controlling specific muscle groups. Learning or improving a motor skill may require reorganisation of the cortical areas controlling relevant muscles to accommodate the new skill. To test this idea we studied a group of elite badminton players that were highly skilled in their dominant playing arm. Transcranial magnetic stimulation …

Frequency Of Attainment Of Plateau In Maximal Oxygen Consumption In Differentially Trained Athletes, Jeffrey Michael Seda

Masters Theses

A plateau in oxygen consumption during exercise testing has been considered a requisite indicator of achievement of true maximal oxygen consumption. The wide range of reported percentages of subjects revealing a plateau (7 to 80 percent) indicates that closer analysis of factors that may influence plateau attainment is necessary. This study examined the frequency of plateau attainment in two groups of differentially trained subjects. One group (TR) of 12 males (ages 18-36) were trained runners and the other group (WL) of 12 males (ages 18-31) consisted of trained weight lifters. The subjects participated in a series of maximal exercise tests …
