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 is the first authoritative and comprehensive volume dedicated to epicardial adipose tissue (EAT). It provides an up-to-date and highly illustrated synopsis of the anatomical, biomolecular, genetic, imaging features, and clinical applications of EAT and its role in cardiovascular disease. It relays to the reader a contemporary view of the emerging interplay between the heart and adiposity-related diseases. In addition, this volume discusses the clinical implications and therapeutic targets of EAT in atrial fibrillation, heart failure and coronary artery disease. Comprehensive yet focused, Epicardial Adipose Tissue: From Cell to Clinic is an essential resource for physicians, residents, fellows, and medical students in cardiology, endocrinology, primary care, and health promotion and disease prevention.

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.

Book Description
This book describes in detail the multidisciplinary management of obesity, providing readers with a thorough understanding of the rationale for a multidisciplinary approach and with the tools required to implement it effectively. The emphasis is on a translational approach, starting from basic concepts and fundamental mechanisms of the pathology and clinical morbidity. Experts in the field discuss the full range of relevant topics, including the significance of physical exercise, psychological issues, nutritional strategies, pharmacological options and bariatric surgery. Put another way, the book covers all aspects from the bench to the bedside. Physicians, scientists and postgraduate students will all find it to be invaluable in understanding the causes and optimal management of obesity, which has rapidly become a major public health problem.

Book Description
Human communities have used Physical Education all over the world to develop fitness for survival in the struggle for existence, including the capacity for protection against enemies. Physical exercise, combative activities, and endurance training have been practiced in ancient times to prepare youth for the defense of the country and for developing unity in the society. Although the most opportune time for developing lifelong fitness habits in the childhood years, it is in the late teens and early twenties when a fitness consciousness among men and women is realized. At this stage in life, people reach physical maturity and the body is at its natural peak of physiological efficiency and health. However, it can be observed that in the late twenties and early thirties, the natural fitness begins to disappear. Lack of exercise begins to show its effect.
