To improve adolescent lifestyles and health, an understanding of leisure-time representations and activity patterns is needed to provide information for targeting interventions. Purposes: To identify leisure-time activities (LTA) representations clusters and analyse their physical activity (PA) levels. Method: A total of 387 adolescents (217 girls; 17,1±1 years) answered to a questionnaire about informal and formal PA and the importance attributed to LTA. Using factor analysis and cluster analysis, five different groups of valuing LTA were formulated. Kruskal-Wallis was used to compare PA among groups. Results: Cluster 1 (no sociable; 8.4% of all students) was characterized by valuing school and home activities but not social relationships. Cluster 2 (eclectics; 36.6%) attributed a high importance to all components of LTA. Cluster 3 (artists; 23.0%) valued music and recreation activities, but attributed low importance to other LTA. Cluster 4 (sporty; 16.4%) considered that sport and social relationships were important but not music. Cluster 5 (non sporty; 15.6%) valued music, sedentary screen and school activities, and attributed low importance to sport. All groups present low levels of PA. No differences were found between clusters regarding informal PA. Comparing to other groups, the “non sporty” presented significant lower levels of formal PA (M=0.4 Sessions/Week). The “sporty” adolescents had higher levels of formal PA (M=2.4 S/W) differing significantly from other clusters, but not from the “no sociable” (M=1.5 S/W). Conclusion: Complex clusters were identified based on adolescents representations of LTA. The understanding of what adolescents value and do can be crucial to promote PA during leisure-time, but other PA correlates need to be considered.
