Physical Activity And Changes In Abdominal Fat Over 18 Months: A Prospective Study Of Middle-Aged Women, Lance Eric Davidson
Physical Activity And Changes In Abdominal Fat Over 18 Months: A Prospective Study Of Middle-Aged Women, Lance Eric Davidson
Theses and Dissertations
Objective: To investigate the extent to which changes in physical activity predict changes in abdominal fat in women over an 18-month period, while statistically controlling the effects of possible confounders, such as age, total body fat percent, and energy intake. Design: A prospective cohort design over 18 months. There was no intervention or treatment. Changes in objectively-measured physical activity were used to predict changes in abdominal fat over the study period. Subjects: 110 healthy, middle-aged women (mean: 41.3±3.3 yrs), primarily Caucasian, educated, and married. Measurements: An objective measure of physical activity (ACT) using CSA accelerometers, worn continuously for 7 consecutive …
A Comparison Of Youth Participation Motives In Organized Sports, Kirsty L. Carrihill
A Comparison Of Youth Participation Motives In Organized Sports, Kirsty L. Carrihill
Legacy ETDs
Youth participation in organized physical activity has increased by more than 5 million in the last decade (Smith & Smoll, 2002). Of the 48 million youth 8 to 16 years old in the United States, 20 million participated in organized sport (Gould & Petlichkoff, 1998; Seefeldt & Ewing, 1997; Smith & Smoll, 2002). Currently, the average age for youth to begin participating in organized sports in, or outside of, school is 11 years old (Klint & Weiss, 1986; Smith & Smoll, 2002). Although participation rates have increased, there are significant numbers of youth who drop out of sport. Over one-third …
Gender Differences In Participation Of Physical Activities: A Comprehensive Model Approach, Kay Gordon Daigle
Gender Differences In Participation Of Physical Activities: A Comprehensive Model Approach, Kay Gordon Daigle
LSU Doctoral Dissertations
The purpose of this study was to examine the interrelationships among gender, perceptions of peer, parent, and teacher support, perceived value and meaningfulness, perceived competence, and the intention to be physically active within a proposed model. Female and male students (N=801) enrolled in a traditional multi-activity physical education class responded to a 52-item questionnaire addressing the constructs in the model. Structural equation modeling, using LISREL, was used to identify the relationships among the constructs. Gender differences emerged in this model through direct paths as well as indirect paths among these variables. Girls were more influenced than boys by their perceptions …
Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park
Collective Efficacy: A Framework For Understanding Classroom Teacher's Perceptions Of Integrating Physical Activity, Melissa Ann Park
LSU Doctoral Dissertations
Children’s physical inactivity is becoming an important health concern, and it has been suggested by professionals that school programs can be important in the effort to increase activity levels. Physical education specialists cannot achieve the goal of significantly increasing children’s activity in isolation, and it is apparent that whole school programs at the elementary level have the potential to foster active lifestyles. If those programs are to be successful, all school personnel must play a role, so it is important to find ways to facilitate their involvement. The purpose of this study was to use collective efficacy as a framework …
Using Self-Determination Theory To Understand African American Women's Physical Activity Patterns, Joan B. Landry
Using Self-Determination Theory To Understand African American Women's Physical Activity Patterns, Joan B. Landry
LSU Doctoral Dissertations
Physical inactivity is a major health risk factor in our society. Women and minority populations are especially at risk with regard to physical inactivity. This three-part study employed quantitative and qualitative methodologies to investigate physical activity behaviors in middle aged and older African American women. This population was chosen because African American women are the least active segment of our society. In the first phase, a quantitative approach was used to investigate relationships between Self-Determination and the Stage of Change for physical activity in a sample of 105 African American women. This study provided validation for using this theoretical approach …
