Children, Obesity and Exercise
Throughout the developed world there is an increasing prevalence of childhood
obesity. Because of this increase, and awareness of the risks to long-term health
that childhood obesity presents, the phenomenon is now described by many as a
global epidemic.
Children, Obesity and Exercise provides sport, exercise and medicine students
and professionals with an accessible and practical guide to understanding and
managing childhood and adolescent obesity. It covers:
• overweight, obesity and body composition;
• physical activity, growth and development;
• psycho-social aspects of childhood obesity;
• physical activity behaviours;
• eating behaviours;
• measuring children’s behaviour;
• interventions for prevention and management of childhood obesity.
Children, Obesity and Exercise addresses the need for authoritative advice and
innovative approaches to the prevention and management of this chronic prob-
lem.

Routledge’s International Studies in Physical Education and Youth Sport series aims
to stimulate discussion on the theory and practice of school physical education,
youth sport, childhood physical activity and well-being. By drawing on interna-
tional perspectives, in terms of both the background of the contributors and the
selection of the subject matter, the series seeks to make a distinctive contribu-
tion to our understanding of issues that continue to attract attention from policy-
makers, academics and practitioners.
International Council of Sport Science and Physical
Education (ICSSPE)
The International Council of Sport Science and Physical Education (ICSSPE)
is an international umbrella organization with a diverse and well-recognized
institutional membership worldwide. ICSSPE has formal associate relations with
UNESCO, is a recognized organization of the International Olympic Committee
(IOC) and cooperates with the World Health Organization (WHO) and other
international bodies. ICSSPE promotes and disseminates a wide range of scien-
tific information and facilitates communication between organizations active in
the fields of sport, sport science and physical education. ICSSPE’s comprehensive
website is updated on a regular basis to share knowledge, report events and an-
nounce newly published resources. It is just one of the tools ICSSPE uses to build
stronger international cooperation and bridge the gap between developed and de-
veloping countries.
Since overweight and obesity has become such a critical and multi-faceted
issue for all nations it is ICSSPE’s aim that all persons, institutes and organizations
involved in sport and sport science keep up to date with latest research, strate-
gies and interventions and understand their role in prevention, identification and
management of the conditions.
