The aim of the European Group for Paediatric Work Physiology is to promote the in ternational exchange of scientific information relevant to the physiology of exercise in of physiologists, paediatricians, and physical growing individuals. The group consists educators. The main purpose of these meetings has been to provide scientists in this field with an informal and efficient channel for mutual discussion. Meetings have previously been held in the Federal Republic ofGermany, Czechoslo vakia, Israel, Belgium, Canada, and Sweden. This time, it was a great honor us to be entrusted with the organization ofthe Tenth Symposium ofPaediatric Work Physiolo gy. The congress took place in Joutsa, a small community in central Finland.It was our wish to bring the group together in the middle of the Finnish summer in a forest hotel by one of our thousands of lakes, providing a peaceful and stimulating atmos phere for discussions on recent research activities. The meeting was fInancially assisted by the Finnish Ministry ofEducation, the com munity of Joutsa, the Rantasipi Joutsenlampi Hotel, Joutsa, as well as Tunturipyorii, Turku, Finland. We wish to express our sincere gratitude to all the sponsors. We would like to thank all the participants for their valuable contributions. We believe that the papers presented will greatly enhance further understanding and re search in the work physiology of children and adolescents.
