The Effects Of Circular And Linear Exercise On Articular Cartilage In Sheep, Kristine Vernon
The Effects Of Circular And Linear Exercise On Articular Cartilage In Sheep, Kristine Vernon
All Dissertations
Excessive exercise may induce osteoarthritis (OA), or degeneration, of articular cartilage, which is a leading cause of lameness and decreased use in horses. The purposes of this study were to utilize a sheep model to determine the effects of circular and linear exercise on the macroscopic and microscopic characteristics of articular cartilage in the metacarpal-phalangeal (MCP) joint and to evaluate biochemical changes in serum and synovial fluid compared to non-exercised control lambs.
Twenty lambs were randomly assigned to three groups: circular exercise (C, 8.5m diameter; n = 8), straight-line exercise (S, treadmill; n = 8) and non-exercised control (CON, n …
Reasons For Physical Activity And Exercise Participation In Senior Athletes, Deborah Lynne Fife
Reasons For Physical Activity And Exercise Participation In Senior Athletes, Deborah Lynne Fife
Theses and Dissertations
Research on physical activity and exercise in the elderly is limited. This study used the Participation Motivation Questionnaire for Older Adults (PMQOA) to assess reasons for engaging in regular physical activity of participants at the 2007 Huntsman World Senior Games. The 259 subjects ranged from ages 50 to 85 years and were divided into tertiles based on frequency of exercise, determined by self reported weekly exercise time and days for further comparison. The most commonly reported reasons for exercise were to stay healthy, keep physically fit, and stay in shape. A previously conducted factor analysis on the PMAOQ revealed six …

Brachial Artery Flow Mediated Vasodilation: Effect Of Chemical Analytes, Diet, Exercise, And Genetic Markers, Joanie Brocato Wilson

The goal of this research was to gain a better understanding of interplay between molecular biology, physiology, biochemistry, functionality with disease and interventions. The primary findings of the first study were that there was a significant inverse correlation between homocysteine and brachial artery flow mediated dilation (BAFMD) and baseline brachial artery diameter. Interestingly, there was a significant difference in BAFMD between methylene tetrahydrofolate reductase (MTHFR) genotype groups. Regression analysis indicated that the MTHFR genotype, homocysteine and age were significant predictors of BAFMD. The second study revealed that vascular reactivity as measured by BAFMD was modifiable. A meta-analysis of 22 intervention …
Exercise And Peripheral Vascular Function In Health And Disease, Arturo Arce
Exercise And Peripheral Vascular Function In Health And Disease, Arturo Arce
LSU Doctoral Dissertations
“Chronic disease will never reach its clinical horizon to compromise health if it is attacked at its origin” [1]. Knowledge that one’s risk for cardiovascular events is related to the severity of endothelial dysfunction, and evidence that exercise training can improve endothelial function, has prompted speculation that measures of vascular function may serve as a “barometer” for cardiovascular health. This dissertation consists of three experiments intended to study vascular function and the manner in which it may influence or may be influenced by physical function. Project one examined the influence of high and low volume circuit weight training on forearm …
