Should scientific congresses take place in connection with Olympic Games, and should science be represented not only in the form of applied science engaged in the care of athletes, but also as an informing, reflecting and critical authority? The Organizing Committee for the Games of the XXth Olympiad answered this question in the affirmative, and the results have justified this decision. The invitation sent out by the Organizing Committee was accepted by numerous eminent scholars and many participants from all over the world; it was their merit that the general topic of the congress could be discussed in manifold ways under various aspects and without prejudice. For this reason, they deserve our gratitude and appreciation. By now, the congress report has been completed. It is part of the total scientific concept which includes the preparatory publication, "The Scientific View of Sport­ Perspectives, Aspects, Issues", the congress itself and the present report; and, in close connection therewith, the exhibitions, "100 Years of German Excavation Work in Olympia", "Sport and Medicine" and the literary exhibition. It is to be hoped that this report will prove an important source of information and a stimulus for discussion among participants and scholars, students, teachers and coaches; and that it will safeguard the fruitful continuation of the work initiated by the Munich congress. Thanks are due to those who took pains in preparing this document. It will be an essential element within the framework of all that will remain of the Olympic Games of 1972.
