Racial Differences In Self-Efficacy Expectations For Exercise, Selena P. Smith Dec 2013

Racial Differences In Self-Efficacy Expectations For Exercise, Selena P. Smith

Honors Theses

This project examined the link between race and self-efficacy. Self-efficacy pertains to an individual’s confidence in ability to complete or engage in a particular task or activity (Bandura, 1986). Prior research shows that self-efficacy has a great influence on exercise initiation and adherence (Bandura, 1986; Dishman, 1982; Rodgers and Sullivan, 2001). Research also supports that Caucasians are more likely to participate in exercise than African Americans (Centers for Disease Control and Prevention, 2000).

Participants included 51 females, 31 Caucasians and 20 African Americans, between the ages of 18 and 50 years old. The women were recruited from local fitness gyms, …

A Home-Based Exercise Intervention To Increase Physical Activity Among People Living With Hiv: Study Design Of A Randomized Clinical Trial, Jason R. Jaggers, Wesley Dudgeon, Steven N. Blair, Xuemei Sui, Stephanie Burgess, Sara Wilcox, Gregory A. Hand

Faculty Scholarship

Background

While combination antiretroviral therapy has extended the life expectancy of those infected with human immunodeficiency virus (HIV), there is a high prevalence of comorbidities that increase the risk of cardiovascular morbidity and mortality among people living with HIV/AIDS (PLWHA). The side effects associated with antiretroviral therapy (ART) lead to multiple metabolic disorders, making the management of these metabolic issues and risk of cardiovascular disease (CVD) in those treated with ART a critical issue. Clinical research trials, primarily clinical exercise, rarely include this population due to unique challenges in research methods with underserved minority populations living with a life threatening …

Integrating Movement And Science To Promote Physical Activity And Academic Performance In Middle School Children, Kevin E. Finn, Kyle Mcinnis

Health Sciences Faculty Publications

Background: Recommendations from leading U.S. health agencies concerned with reducing childhood obesity call for increased physical activity during school and afterschool environments. Methods: We developed the Active Science curriculum, which is a variety of activity-based lessons (e.g., nature hike, dance class, walk at local park, treadmill at local YMCA) and incorporated them into traditional science classes and after school programs for middle school children in a low-income, ethnically diverse community. Following the activity experiments, students and teachers uploaded data from devices to an interactive website that provided inquiry-based exploratory learning of science content. Results: Physical activity results showed that the …


Associations Between Resting Metabolic Rate And Energy Storage In Young Adults, Robin Shook Jan 2013

Associations Between Resting Metabolic Rate And Energy Storage In Young Adults, Robin Shook

Theses and Dissertations

At the most basic level obesity is the result of a chronic imbalance between energy intake and energy expenditure. However, the exact etiology is considerably more complex and may involve a variety of physiological and behavioral factors. Metabolic disturbances, including reduced fat oxidation as measured by the respiratory quotient (RQ) and reduced resting metabolic rate (RMR), have been identified as possible predictors of changes in body weight and body composition. RMR represents the largest component (60-80%) of caloric expenditure that contributes to total daily energy expenditure in humans and has high inter-person variability (±25%) but not within individuals (<±5%). The cause of this variability between individuals and the exact role of RMR and RQ in determining body weight and body composition are uncertain.
