Abstract
Summary Young people differ widely in their sports behavior and show high drop-out rates from organized sports. One explanation from socialization theory refers to the transgenerational mediation of sports behavior and orientations toward sports within the family. The present study investigates the relevance of orientations toward sports and behavioral patterns within the family to young people’s sports behavior. Using methodological triangulation between multiple linear regression and qualitative interviews of young people between the ages of 15 and 20, the study investigates the relationship between individual sports behavior and family influences such as the importance of sports, regularity of sports activity within the family, social support, sports-related health awareness, and communication about sports in the family.
