Cognitive Behavior Modification And Exercise + Group Counseling For Patients After Bariatric Surgery, Janet Buckworth, Caroline Carducci, Shirley Kindrick, Dean Mikami, Dara Schuster, Katharine Stough, Bradley Needleman

International Journal of Exercise Science: Conference Proceedings

The growing obesity epidemic is paralleled by an increasing number of bariatric surgeries. Patients lose significant weight within the first 12-18 months post-surgery with corresponding resolution of many co-morbidities. However, weight loss stabilizes after 18-24 months and 50% or more of patients eventually regain weight (Bond, Phelan, Leahey, Hill, & Wing, 2009; Magro, et al., 2008). Weight regain after loss is associated with return of co-morbidities and deteriorations in health-related quality of life and mood (Karlsson, Taft, Ryden, Sjostrom, & Sullivan, 2007). The purpose of this pilot study was to analyze the effects of a post-surgical behavioral plus counseling intervention …

Improving Secondary Stroke Prevention Among Underserved African Americans: Moving Beyond Health Attitudes, Chelsea Gilts, Lisa Hughes, Gina Evans Hudnall

International Journal of Exercise Science: Conference Proceedings

Obesity, a known risk factors for stroke, poses a great health risk for the African American community. Beliefs about health locus of control (HLOC) are predictive of many health behaviors related to both obesity and stroke prevention. Some have recommended targeting health interventions to individuals with internal HLOC, as they tend to be more amenable to changing health behaviors, but this can be exclusionary to African Americans, who tend to have higher levels of external locus of control. The present study is a pretest-posttest randomized control design examining the impact of a brief, CBT-based health management intervention developed for overweight …

Elucidating Functional Roles For Myogenin In Adult Skeletal Muscle Metabolism, Exercise Capacity, And Regeneration, Jesse Flynn

Dissertations and Theses (Open Access)

The four basic helix-loop-helix myogenic transcription factors, myogenin, Myf5, MRF4, and MyoD are critical for embryonic skeletal muscle development. Myogenin is necessary for the terminal differentiation of myoblasts into myofibers during embryogenesis, but little is known about the roles played by myogenin in adult skeletal muscle function and metabolism. Furthermore, while metabolism is a well-studied physiological process, how it is regulated at the transcriptional level remains poorly understood. In this study, my aim was to determine the function of myogenin in adult skeletal muscle metabolism, exercise capacity, and regeneration. To investigate this, I utilized a mouse strain harboring the Myogflox …
