Book Description
This study examined personal, social, and demographic factors related to physical activity (PA) level and body mass index (BMI) in adolescent African American (AA) females. The participants were 211 AA females from selected parochial schools in a city in the southern U.S. Participants completed the Physical Activity Determinant Scale (PADS: Mitchell & Kontos, 2002), the Three Day Physical Activity Recall (3DPAR: Weston, Petosa & Pate, 1997), the Leisure Time Exercise Questionnaire (LTEQ: Godin & Shepard, 1985), and demographic items. Height and weight measures were taken to assess BMI. Results from logistic regression indicated that the personal factor was a significant (p

Book Description
"The purpose of this study was to develop a better understanding of the physical activity behavior of Black female adolescents age 14-18 in the Charlotte, NC public school community by examining the relationship between physical activity and self-efficacy, social support, outcome expectations, and physical environment. The study sample consisted of 96 girls ages 14-19 from a public high school in Charlotte, North Carolina. Participants volunteered to complete a survey with demographic, physical activity (PA), and psychosocial questions. The predictor variables were self-efficacy and physical activity self-efficacy, social support, outcome expectations, and physical environment. The dependent variable was physical activity participation. Correlational analysis was employed to examine the relationship of the four predictor variables to physical activity. Self-efficacy was shown to be correlated with PA. The strongest correlation was between physical activity self-efficacy and PA. Correlations between outcome expectations and PA for the total sample were low and not significant. Total social support, family and friend social support were correlated with PA as well. Physical environment was not significantly related with PA for the Black adolescents in this study. Multiple regression was used to determine the relative strength of the four main predictor variables on the dependent variable of physical activity level. For the total sample, the four predictor variables explained 24% of the variance in physical activity participation. Of these variables, physical activity self-efficacy makes the largest unique contribution (beta=.36) with a significance level of .002. In order to understand PA habits and perceptions among Black adolescent females, the last section of the survey included 14 open-ended questions. Most Black participants understand the health benefits of physical activity, but cited tiring and sweating factors as reasons why they do not participate in physical activity. Findings suggest increasing physical activity self-efficacy and providing social support, as well as allowing girls to have a choice in their physical activity and offering activities they consider fun, may lead to increased physical activity among Black adolescent girls."--Abstract from author supplied metadata.

Book Description
This dissertation examined relationships between predictors of physical activity (psychosocial and environmental resources), measures of physical activity (PA), and physical fitness in a sample of 192 adolescents (mean age 14.79 ± 0.46 years; 105 male/87 female). Psychosocial resources (perceived competence and social support for PA) were assessed via self-report. Environmental PA resources were assessed using Geographic Information Systems (GIS) technology. All gyms, schools, bike trails, parks and athletic fields within .5 miles of a participant's home were geocoded and summed to create a measure of environmental PA resources. Four measures were used to assess PA: accelerometry, 3-day recall, and self-reported sports participation both in- and out-of school. Fitness was assessed via dual energy x-ray absorptiometry (DEXA, which measured percent body fat), body mass index (BMI) percentile (calculated from height and weight), and maximal oxygen uptake (VO2peak during a cycle ergometer ramp-type fitness test). Linear regression analyses revealed: The associations between environmental resources and both PA (school sports participation) and fitness (BMI percentile and body fat) confirmed hypotheses (i.e. access to more environmental resources was associated with increased PA and fitness); however, the ways in which environmental resources were associated with PA and fitness depended upon adolescent gender. Perceived competence significantly predicted all measures of PA and fitness in the expected (positive) direction. Social support positively predicted all measures of PA and VO2peak. Further, school sports participation partially mediated the relationship between social support and VO2peak; however, there was no evidence that the PA variables mediated the relationship between perceived competence and fitness. The interaction between environmental resources and social support for PA was significantly associated with school sports participation: Adolescents who had greater access to environmental PA resources and also greater social support were more likely to engage in PA than adolescents with lower levels of environmental resources, social support, or both. Results are discussed in terms of Social Ecological Theory and suggestions are presented to inform future research and intervention.

Book Description
Background: Ecological models posit that interactions among factors at multiple levels (e.g., individual, psychosocial, and environmental) influence physical activity (PA). However, interactions involving environmental factors are the least understood. Intervention studies also suggest PA behavior change may depend on the environments in which participants are encouraged to be active but such evidence from interventions targeting Latinos is limited. Methods: Chapter 2 tested interactions between neighborhood environmental and socio-demographic factors on total moderate-to vigorous physical activity (MVPA) among an international adult sample (N=10,258). Chapter 3 examined interactions between neighborhood environmental and psychosocial factors on context-specific PA among an adolescent sample from the Baltimore/Seattle regions (N=910). Chapter 4 assessed the moderating effects of neighborhood environmental factors on the impacts of a physical activity intervention targeting Latinas in San Diego, CA at 12-months post-intervention (N=319). Results: Chapter 2 found moderating effects by education and gender on the association between safety from crime and meeting high PA levels, with inverse associations found only among the high-education group and men. Education and gender moderated associations of safety from crime and the presence of transit stops with meeting minimum PA guidelines, with positive associations found for safety from crime only among women and the presence of transit stops only among men and the high-education group. Chapter 3 found moderating effects by decisional balance on the association between recreation facility density and neighborhood leisure-time PA among female adolescents, with a negative association found only among those with high decisional balance. Decisional balance also moderated the associations of neighborhood walkability with non-school MVPA among females and non-neighborhood leisure-time PA among males, with positive associations only among adolescents with high decisional balance. Chapter 4 showed higher total MVPA and leisure-time MVPA at 12-months post-intervention among participants with favorable perceived neighborhood aesthetics than those with less favorable evaluations. Conclusions: This dissertation supports the ecological models' hypothesized interactions between environmental and individual/psychosocial factors on PA and the moderating role of the neighborhood environment on the impacts of a multilevel PA intervention targeting Latinas. Findings support global efforts targeting multiple levels of influence to promote population PA, health, and environmental sustainability.

Book Description
The positive benefits of physical activity for physical and mental health are now widely acknowledged, yet levels of physical inactivity continue to be a major concern throughout the world. Understanding the psychology of physical activity has therefore become an important issue for scientists, health professionals and policy-makers alike as they address the challenge of behaviour change. Psychology of Physical Activity provides comprehensive and in-depth coverage of the fundamentals of exercise psychology, from mental health, to theories of motivation and adherence, and to the design of successful interventions for increasing participation. Now publishing in a fully revised, updated and expanded fourth edition, Psychology of Physical Activity is still the only textbook to offer a full survey of the evidence base for theory and practice in exercise psychology, and the only textbook that explains how to interpret the quality of the research evidence. As the field continues to grow rapidly, the new edition expands the behavioural science content of numerous important topics, including physical activity and cognitive functioning, automatic and affective frameworks for understanding physical activity involvement, new interventions designed to increase physical activity (including use of new technologies), and sedentary behaviour. A full companion website offers useful features to help students and lecturers get the most out of the book during their course, including multiple-choice revision questions, PowerPoint slides and a test bank of additional learning activities. Psychology of Physical Activity is the most authoritative, engaging and up-to-date book on exercise psychology currently available. It is essential reading for all students working in behavioural medicine, as well as the exercise and health sciences.
