Book Description
This important monograph summarizes a comprehensive study on the maturation of walking in normal children. Research, undertaken at one of the world's leading gait analysis centers, involved over 400 studies on a total of nearly 300 children in ten age-groups from one to seven years. Data are presented on anthropometric measurements; tests of developmental progress; time/distance parameters such as stride length and walking velocity; twelve joint angles on each side measured throughout the gait cycle; dynamic electromyography of phasic activity in seven lower-extremity muscle groups; and force measurements including vertical force, fore/aft shear, medial/lateral shear and torque. At each age, composite joint-angle graphs and time/distance parameters are brought together with film tracings of a representative child in that age group. In addition, advanced methods of statistical analysis have been applied to the joint-angle data to define prediction regions within which ninety-five percent of normal children should lie throughout the gait cycle. Finally, a "decision tree" is presented from which a fitted age can be inferred for a subject based on non-age-specific data gathered in a motion analysis lab. Practical applications are demonstrated in a chapter devoted to two case studies.

Book Description
This book addresses a topic that has received surprisingly little attention to date--the health and social needs of young adults with physical disabilities. Following an extensive review of the contemporary literature on the subject, the authors report an in-depth study on a large sample of physically disabled 18- to 25-year olds living in two survey areas, one urban and one semirural. The study, which included pediatric examinations and interviews by a social psychologist, found that a large proportion of subjects face social and medical problems, for instance: They have serious health needs that are not being met by the statutory services; they left school with less than adequate skills to enable them to lead an independent adult life; they are without a daytime occupation or attend day centers that are described as "unstimulating" places; they do not receive all the financial benefits to which they are entitled; they are isolated from their peers and lack the social skills to interact with others in a positive and successful way. Parents and guardians were also found to receive little physical or emotional support. These findings underline the need for a better system of providing and coordinating services for this client group, and the authors call for the formation, within each local health authority area, of an "Adult Disability Service" that would have a clinical and planning role in terms of health care and that would act as a linchpin in the coordination of health, educational, social, and voluntary services. Although this work relates specifically to service provision in the United Kingdom, it is felt that the conclusions and recommendations are also broadly applicable to the situation in other countries.

Book Description
Strength and Conditioning for Young Athletes offers an evidence-based introduction to the theory and practice of strength and conditioning for children and young athletes. Drawing upon leading up-to-date research in all aspects of fitness and movement skill development, the book adopts a holistic approach to training centred on the concept of long-term athletic development and the welfare of the young athlete. While other textbooks focus on a single aspect of youth trainability, this book explores every key topic in strength and conditioning as applied to young people, including: talent identification motor skill development strength, power and plyometrics speed and agility metabolic conditioning mobility and flexibility periodization weightlifting myths overtraining and injury prevention nutrition. Written by a team of leading international strength and conditioning experts and paediatric sport scientists, every chapter includes programming guidelines for youths throughout childhood and adolescence to show how the latest scientific research can be applied by coaches to optimize young athletic potential. This is an essential resource for all students of strength and conditioning or paediatric exercise science, as well as any coach or athletic trainer working with children and young people.
