Book Description
[Truncated abstract] Regular engagement in physical activity is proven to decrease the risk of numerous chronic diseases and to improve mental well-being. However, many children and adults around the world fail to engage in sufficient levels of activity required to produce health benefits, with reports showing physical activity levels still on the decline. Perhaps because of this increase in sedentary lifestyles, obesity has become one of the biggest public health threats in the 21st century. Furthermore, both obesity and physical inactivity are closely related to psychological health, and may play an important role in shaping self-perceptions and feeling of general well-being. '...' In the first study, physical status, physical activity levels, and social physique anxiety measures were obtained from an adolescent sample of 259 participants. Partial correlation analyses revealed that physical activity involvement was not directly linked with physical status; however, both factors were significantly associated with social physique anxiety, which suggested evidence of an indirect link between the two constructs. That is, analyses showed that poor physical status was associated with higher levels of physique anxiety, which in turn linked to low engagement in physical activity. In addition, age and gender effects emerged, revealing unique differences in the ways in which these three variables may be related. To cross-validate and further examine these relationships STUDY 2 extended the range of self-perception measures to include a multidimensional assessment of physical self-concept and a global self-esteem measure along with physique anxiety. These variables were assessed in a German adult sample (N = 229), again alongside measures of physical status and physical activity involvement. Consistent with STUDY 1, no direct link was found between physical status and levels of physical activity involvement. However, evidence of an indirect link did emerge as both variables were related to multiple dimensions of physical self-concept, thereby reinforcing and extending the findings from STUDY 1. Furthermore, age effects emerged for physical self-concept, which had not been confirmed in previous research on physical self-concept. STUDY 3 employed a longitudinal design and investigated changes in physical self-concept, global self-esteem and social physique anxiety before, during, and after participation in a 12-week weight management programme. Participants (N = 63) were assigned to one of three conditions: (1) cognitive-behavioural treatment only, (2) cognitive-behavioural treatment and exercise, and (3) non-treatment control. Statistical analyses revealed a small, but significant reduction in weight for members of both treatment groups. Relative to controls, both treatment groups also improved on a variety of physical self-concept dimensions. At the same time, however, significant group main effects suggested that a weight-loss program incorporating exercise involvement may provide physical self-concept benefits that go beyond those obtained with standard CBT regimes. Collectively, these studies add to the growing body of literature on the connections between physical activity, self-perceptions and physical status. They also highlight the importance of involvement in habitual physical activity throughout the lifespan. Findings are discussed with regards to their contribution to the extant literature, and applied implications, limitations, and future directions are considered.

Book Description
Physical inactivity is a key determinant of health across the lifespan. A lack of activity increases the risk of heart disease, colon and breast cancer, diabetes mellitus, hypertension, osteoporosis, anxiety and depression and others diseases. Emerging literature has suggested that in terms of mortality, the global population health burden of physical inactivity approaches that of cigarette smoking. The prevalence and substantial disease risk associated with physical inactivity has been described as a pandemic. The prevalence, health impact, and evidence of changeability all have resulted in calls for action to increase physical activity across the lifespan. In response to the need to find ways to make physical activity a health priority for youth, the Institute of Medicine's Committee on Physical Activity and Physical Education in the School Environment was formed. Its purpose was to review the current status of physical activity and physical education in the school environment, including before, during, and after school, and examine the influences of physical activity and physical education on the short and long term physical, cognitive and brain, and psychosocial health and development of children and adolescents. Educating the Student Body makes recommendations about approaches for strengthening and improving programs and policies for physical activity and physical education in the school environment. This report lays out a set of guiding principles to guide its work on these tasks. These included: recognizing the benefits of instilling life-long physical activity habits in children; the value of using systems thinking in improving physical activity and physical education in the school environment; the recognition of current disparities in opportunities and the need to achieve equity in physical activity and physical education; the importance of considering all types of school environments; the need to take into consideration the diversity of students as recommendations are developed. This report will be of interest to local and national policymakers, school officials, teachers, and the education community, researchers, professional organizations, and parents interested in physical activity, physical education, and health for school-aged children and adolescents.

Book Description
Despite the many health benefits of being physically active, nearly a quarter of U.S. adults and adolescents report no participation in leisure-time physical activity. It is recommended that children and adolescents participate in physical activity for at least 60 minutes daily at moderate or vigorous intensity. In addition to potentially enhancing academic performance, participation in physical activity may also influence perceptions of physical appearance and global self-esteem, which tend to decrease with age in adolescent females. The purposes of this study were to: (a) examine the prevalence of overweight and obesity and the percentage of adolescent females from a rural community that meets physical activity recommendations; (b) examine the relationship of body composition, physical activity, and sedentary behavior on academic performance; and (c) examine the relationship between physical activity and physical self-concept among adolescent females. Thirty adolescent females (mean age = 15.6 " 1.3 years) wore an Actigraph GT1M accelerometer for seven consecutive days, set to measure in 15-second epochs. Age specific cutpoints were used to determine minutes of sedentary behavior and light, moderate, vigorous, and moderate-to-vigorous physical activity (MVPA). Participants completed the Physical Self-Description Questionnaire (PSDQ) to assess how they perceive themselves physically. Height, weight, and percent body fat were measured. Grade point averages (GPA) were obtained from school records. Regression analysis was performed to predict GPA from measures of body composition, sedentary behavior, and MVPA. Measures of physical activity and sedentary behavior were correlated with PSDQ subscale scores with Pearson correlations. Thirty percent of participants (n = 9) were obese (BMI [greater than or equal to] 95th percentile) and another 36% (n = 11) were overweight (BMI between the 85th and 94th percentiles). None of the participants accumulated [greater than or equal to] 60 minutes of MVPA per day. Daily MVPA averaged 9.7 (" 7.1) minutes. Percent fat (r = -.51), minutes of MVPA (r = .34), and time spent in sedentary behavior (r = .32) were significantly correlated (p
