Students' Construction Of The Body In Physical Education, Laura Azzarito
LSU Doctoral Dissertations
Recently, physical education researchers have been concerned about the results of national studies reporting young people's low level of participation in physical activity and health problems associated with inactivity. In general girls are less active than boys, and youth from low socioeconomic classes are less active and are more likely be unhealthy than middle or upper class youth. Blacks have the highest risks of health problems and the highest levels of physical inactivity. Among a number of recommendations included in Healthy People 2010, physical education has been identified as a fundamental site for addressing today's challenges. According to physical education …
Leptin In Horses: Influences Of Body Condition, Gender, Insulin Insensitivity, Feeding, And Dexamethasone, Joshua Allen Cartmill
Leptin In Horses: Influences Of Body Condition, Gender, Insulin Insensitivity, Feeding, And Dexamethasone, Joshua Allen Cartmill
LSU Doctoral Dissertations
The experiments described herein were designed to answer questions that arose from initially attempting to determine whether treatment with dexamethasone increased concentrations of leptin in geldings. Dexamethasone treatment did in fact increase leptin concentrations in mares, geldings, and stallions. Additional experiments were designed to determine leptin's interaction, not only with the adrenal axis, but with the thyroid axis, the growth hormone/insulin-like growth factor-1 axis, as well as glucose and insulin metabolism in geldings, mares, and stallions. During the course of these experiments, differences in leptin concentrations in the horse were attributed to degree of body condition, gender, and feeding time. …
