Book Description
Body image is among many psychological variables that are related to physical activity and dietary practices. Body image begins to develop in childhood and takes on increased importance during adolescence. Interventions aimed to improve physical activity and nutrition in pre-adolescents may have effects upon body image during this key developmental period. The purpose of the current study was to examine the secondary effects of a larger trial of physical activity and nutrition on body image in pre-adolescents. Based on Social Cognitive Theory, several personal, behavioral, and environmental factors are hypothesized to affect body image and were examined in this study. It was hypothesized that the intervention would have a significant positive impact on body image. Eighty-four 10-12 year olds (52 females, 32 males) of diverse ethnic backgrounds were recruited for study as part of the Healthy Youth and Parent Program, an on-going trial for physical activity and nutrition. A two-group (intervention and control) pre-post design was used. The intervention consisted of 8 weekly 2-hour sessions during which children participated in fitness activities. Body image was measured by the Eating Disorders Inventory-2, a well-validated measure. Analysis of co-variance revealed no significant direct effect of the intervention on body image, although participants in both conditions showed non-significant improvements in body image from baseline to post-test. Multiple regression analyses were used to examine theoretically hypothesized mediators of body image change, including level of physical activity and fitness, body mass index, and mood. Puberty status, negative self-esteem, and perceived barriers to physical activity were significantly related to body image concerns. The lack of a significant intervention effect on hypothesized mediators precluded the possibility of determining whether changes in these mediators would have affected change in body image. Future studies will need to test the role of hypothesized mediators if a comprehensive theoretical model of body image is to be developed.

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
An imbalance between high energy intake – due to inadequate diet – and reduced energy expenditure – caused by sedentary habits – is believed to create an inherent risk of obesity among individuals. Lifestyle changes among preschool children coupled with health problems (cardiovascular, metabolic, orthopedic, psychological etc.) correlate to an observed increase in body mass index and may even predispose growing children towards obesity in their adult life. Adequate physical activity in the form of regular exercise (in terms of intensity, frequency and duration) has been shown to reduce BMI and have a positive impact on health and physical fitness levels among children. Thus physical activity programs have been applied for obesity prevention and treatment with some degree of success. Physical Activity, Fitness, Nutrition and Obesity During Growth focuses on research findings and recommendations to mitigate obesity risk in children during early growth stages. The reviews presented in this volume give readers an interdisciplinary insight into the realm of obesity as a global epidemic in early childhood. The review also discusses interventions based on physical activity, which can help combat obesity among children while avoiding undesirable strategies (such as strict diets). The book is intended for public health officials, social workers, as well as general medical practitioners and counsellors.

Book Description
This volume presents a review of current research on the relationships between dietary intake, growth, physical activity and exercise in different environments throughout the world, and their impact on health and physical fitness. The combined influence of heredity and environment on the potential for growth and functional development has been hotly debated for many years. Amongst the more critical environmental factors commonly considered are nutrition, physical activity and motor stimulation. This book examines how these factors affect the growth and development of children and youth in developed and developing countries. Characteristics of children from Africa, the Indian sub-continent, Europe, Australia, and North and South America are presented by leading exponents of work in these areas. The contents provide new insights on positive health and optimal somatic and functional development during childhood. It will be of interest to a wide range of scientists and health professionals including pedagogues, exercise physiologists, pediatricians, auxologists, nutritionists, dietitians, anthropologists, human biologists and other medical practitioners.

Book Description
In recent decades, the prevalence of youth obesity has been on the rise (Ogden et al, 2010) highlighting the need for research evaluating interventions targeting eating behaviors and lifestyle activity. Although it is important to examine the impact of interventions on physical activity, fitness, and body composition given their relationship with physical health, it is also important to assess the impact of interventions on mental well-being. Self-perceptions, including self-esteem, are important indicators of mental well-being (Blaine et al., 2006). In fact, Biddle (2011) found poor self-perceptions to be a predominant mental health issue in overweight adolescents. Although exercise is associated with improved self-esteem, the changes in self-esteem are often not large in magnitude (Spence et al., 2005). The greatest improvements are likely to occur in those populations that would benefit the most such as overweight individuals (Lox, Ginis, & Petruzzello, 2010). In addition to exercise, mentoring programs have also had positive effects on youth self-esteem (King, 2002). Thus, exercise combined with mentoring may by an effective strategy for enhancing self-perceptions. This study evaluated the impact of a mentor-based exercise program on the self-perceptions, body composition, physical activity, and fitness level of overweight adolescents. Adolescents participated in mentor-led, weekly exercise sessions for approximately 14 weeks. The program also involved a lifestyle-coaching component through weekly behavioral challenges designed to enhance self-regulatory skills related to physical activity and healthy eating. To date, 28 participants with a mean age of 14 and a baseline BMI of 32 have participated in the mentoring intervention. An additional 12 adolescents were randomly assigned to a wait-list control condition. In addition to fitness (maximum treadmill test), physical activity (accelerometers) and body composition (DXA) assessments, participants completed a questionnaire that examined exercise specific self-perceptions, physical self-worth, and global self-esteem (Whitehead, 1995; Harter 1988) pre/post intervention and after a no treatment maintenance period. A series of 2 (condition) X 2 (time) repeated measures ANOVA's combined with effect size inspection revealed that participants in the mentoring condition showed improved aerobic fitness (d = .44) compared to the control condition, which exhibited a negative change (d = -.06). Participants in the mentoring condition showed increased moderate-vigorous intensity activity (d = .41), compared to the control group (d = .14). While BMI-Z score improvements did not differ across conditions, percent body fat change for the experimental group showed a small, positive change (d = .22), compared to the control group (d = .08). In terms of self-perceptions, mentor participants reported improved self-esteem, physical self-worth, and perceived physical condition with the effect sizes being in the moderate to large range (i.e., d = .52, .79, .82), while the control group showed minimal change (i.e., d = .11, .26, .30). However, when evaluated after a no contact follow-up period, all variables in the experimental condition had regressed toward baseline. These results suggest a mentor-based exercise intervention has a positive impact while adolescents are in the program. However the program does not seem to be effective at helping participants maintain healthy changes when the program ends.
