Physical Activity And C-Reactive Protein Levels: The Confounding Role Of Body Fat Percentage, Kenric Lloyd Russell
Physical Activity And C-Reactive Protein Levels: The Confounding Role Of Body Fat Percentage, Kenric Lloyd Russell
Theses and Dissertations
The purpose of the present study was to examine the cross-sectional relationship between physical activity and C-reactive protein (CRP) in 211 middle-aged women (43.1 + 3.0 years). A secondary objective was to determine the extent to which body fat percentage operated as a confounder in the association between physical activity and CRP. Physical activity was objectively measured using MTI accelerometers, which the subjects wore for seven continuous days. Fasting blood samples were taken, from which CRP was measured using a solid phase ELISA. Body fat percentage was assessed using the Bod Pod. Results showed that physical activity was significantly and …
College Student's Motivation For Physical Activity, Lori Lynn Delong
College Student's Motivation For Physical Activity, Lori Lynn Delong
LSU Doctoral Dissertations
The purpose of this study was to examine college students' motivations to be physically active by merging the perspectives of self-determination theory and the transtheoretical model. The secondary purpose was to examine the effects of a required physical activity course on college students' levels of physical activity. The premise is that both the theory and model can be used to help predict physical activity outcomes. Participants were 277 male and female students at a small private college. Motivation, self-determination, stage of change, self-efficacy, decisional balance, and leisure time activity levels were assessed using an online survey. Results revealed that activity …
Physical Activity Behavior Of University Students: An Ecological Approach, Lisa Gaye Johnson
Physical Activity Behavior Of University Students: An Ecological Approach, Lisa Gaye Johnson
LSU Doctoral Dissertations
Despite the health benefits associated with active lifestyles, a majority of adults do not engage in sufficient levels of physical activity (PA). Few individual-focused interventions have produced sustained changes in PA behavior. Therefore, public health officials are promoting the use of ecological approaches to examine the multidimensional factors that influence choices about PA and other health behaviors. National statistics are mirrored in college populations, with one-half of students in the US failing to meet current PA recommendations and one-third classified as either overweight or obese. In light of this, increasing PA and obesity prevention have been identified as the top …
Self-Determination In Physical Education: Designing Class Environments To Promote Active Lifestyles, Charity Leigh Bryan
Self-Determination In Physical Education: Designing Class Environments To Promote Active Lifestyles, Charity Leigh Bryan
LSU Doctoral Dissertations
The purpose of this study was to investigate the relationships between self-determination, perceptions of the motivational climate, attitude, perceived ability, engagement in physical activity, and health-related fitness indicators. Two structural models related to engagement/intention to engage in physical activity and health-related fitness were tested. The premise of both models is that perceived competence predicts the outcome variables (engagement or health-related fitness), with self-determination, attitude, and motivational climate predicting perceived competence. Participants were 827 sixth, seventh, and eighth graders. Motivation, perceptions of the climate, attitude, perceived competence, and self-reported physical activity levels were assessed using surveys. Pedometers were used to record …
