[en] The findings are presented of an international comparative study of youth sports club members to determine their perspectives on the relationship between school and sport, and the influence of physical education on sport participation and membership of sports clubs. Participants in the study comprised two groups of 344 sports club members and school pupils from Luxembourg and Germany. Differences in terms of age, sex and school type were taken into account. The main findings indicate that school and physical education in both countries only have a slight, indirect influence on young people's decisions to become members of sports clubs and participate in sport. Indeed, the pressures of school may in some cases be an obstacle to intensive sports activity and training outside school. This is particularly so in Luxembourg where students often have to refuse participation in sports competitions and training because of the pressures of school work. Some final thoughts are presented on ways in which school and physical education could become more supportive of youth sport training and club membership, and could give greater encouragement to young people to succeed in competitive and high level sport. [de] In einer Reihe von europäischen Ländern wird derzeit von sportlicher Seite ein Mangel an Sporttalenten beklagt. Eine notwendige Konsequenz dieses als unbefriedigend erlebten Zustandes wird darin gesehen, den sportlichen Nachwuchs in stärkerem Maße zu fördern. Der Einsatz wirkungsvoller Maßnahmen erfordert jedoch vorab eine präzise Zustandsanalyse. Notwendig ist es deshalb, über detaillierte sozialepidemiologische Befunde zur sportlichen Situation der Jugendlichen zu verfügen. Interventionen sind erst dann mit hoher Wahrscheinlichkeit effizient, wenn Verhaltensursachen identifiziert und ihre Veränderbarkeit beurteilt wurden
