Book Description
The primary purpose of fitness and body composition standards in the U.S. Armed Forces has always been to select individuals best suited to the physical demands of military service, based on the assumption that proper body weight and composition supports good health, physical fitness, and appropriate military appearance. The current epidemic of overweight and obesity in the United States affects the military services. The pool of available recruits is reduced because of failure to meet body composition standards for entry into the services and a high percentage of individuals exceeding military weight-for-height standards at the time of entry into the service leave the military before completing their term of enlistment. To aid in developing strategies for prevention and remediation of overweight in military personnel, the U.S. Army Medical Research and Materiel Command requested the Committee on Military Nutrition Research to review the scientific evidence for: factors that influence body weight, optimal components of a weight loss and weight maintenance program, and the role of gender, age, and ethnicity in weight management.

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
In the past few decades obesity rates in the US have reached epidemic proportions in both adults and children. Nearly one-third of American adults are obese, and since 1980, the obesity rates for children 6-11 years and 12-19 have nearly tripled (Centers for Disease Control and Prevention, 2012). Obesity in adults and children is associated with abnormal lipid profiles, insulin resistance and low cardiorespiratory endurance (CRE). The link between disease risk and low CRE has been well established in adults and to a lesser extent in children and adolescents. The PURPOSE of this study was to evaluate the effect of a mentor-led vigorous aerobic exercise program on insulin resistance, body composition, and peak VO2 in overweight and obese adolescents. METHODS Subjects (n=23) for the study were randomly assigned to two groups. Eleven participants were assigned exercise mentors and exercised approximately three times per week for 45 to 60 minutes each session. An additional 12 adolescents were randomly assigned to a control group. Body composition, Peak VO2, and HOMA-IR levels were assessed at pre-, post-, and follow-up testing. A 2 (control vs. experimental) x 3 (pre-, post-, follow-up) repeated measures analyzes of variance (ANOVA) was used to analyze the data using the MANOVA procedure in JMP®. RESULTS No significant intervention effect was observed for body composition measures. Significant effects were observed in Peak VO2max (p = 0.0066) and total treadmill time (p = 0.0116). In the experimental group, effect size, measured by Cohen's d, showed a high effect size (d = 0.88) for Peak VO2max from pre to post test and a moderate decrease in effect size (d = -0.44) from post to follow-up. Similar findings were shown with total treadmill time with a small positive effect size from pre to post (d = 0.29) and a small decrease from post to follow-up (d = -0.33). No significant between group differences were found in HOMA-IR. However, the intervention group's HOMA-IR, improved between baseline and post testing period. The current findings show that independent of weight loss and change in body composition, positive changes in fitness were significantly different from the control group, and the fitness improvements were maintained throughout the duration of the study. Insulin resistance improved for the experimental group from baseline to post testing and was maintained over the 12 week non-intervention follow-up period.CONCLUSION A mentor-led exercise intervention does have potential to be effective at increasing health outcomes independent of weight loss, which can be sustainable after the cessation of the program.

Book Description
This book surveys the entire field of body composition as it relates to performance. It includes a clear definition of terminology and a discussion of the various methods for measuring body composition. The authored papers represent a state-of-the-art review of this controversial field and address questions such as: What is a better measure of body compositionâ€"body fat or lean body mass? Does being overweight for one's height really affect performance? The book also addresses the issue of physical appearance as it relates to body fatness and performance. It includes an in-depth discussion of many of the topics of interest to those involved in sports medicine and exercise physiology.
