RESUMEN
BACKGROUND: Lifestyle sport activities (e.g. parkour or skateboarding) are considered attractive and beneficial for a long-term commitment to physical activity (PA) and might be a great opportunity for adolescents who do not feel comfortable in an organized or competitive atmosphere. The purpose of the study was to assess whether participation in lifestyle activities is associated with moderate-to-vigorous physical activity (MVPA), out-of-school vigorous physical activity (VPA), and sedentary behaviour in adolescents aged 10-15 years, with major demographic variables (sex, age, socioeconomic status) being taken into account. METHODS: Data from a research project linked to the Health Behaviour in School-aged Children (HBSC) survey collected in 2017 in the Czech Republic was used. The sample consisted of 679 participants (303 of them girls) and was selected by quota sampling. Chi-square tests were used to assess differences in involvement in lifestyle activities according to sex, grade, and socioeconomic status. Ordinal and linear regression models were used to analyse the associations of participation in lifestyle activities and selected energy balance-related behaviours. RESULTS: Participation in lifestyle sport activities was significantly associated with a higher level of physical activity (MVPA and out-of-school VPA) after adjustment for sociodemographic factors, as was participation in organized sport. No significant associations were shown for sedentary behaviour. CONCLUSIONS: Adolescents participating in lifestyle sport activities report being more physically active and, in case of doing multiple such activities concurrently, also spending less time sitting than their peers not involved in lifestyle sport activities. As such, lifestyle sport activities seem to represent a feasible way of increasing overall PA level in adolescent population.

OBJECTIVES: Associations between the perceived social and physical environment and self-reported moderate-to-vigorous physical activity (MVPA) and screen time (ST) were examined among adolescents in four European countries. METHODS: Representative samples were surveyed with standardised methodologies. Associations between environmental variables and meeting MVPA recommendations and tertiles of ST were tested in gender-specific logistic regression models. Moderation by country and country-specific relationships were also examined. RESULTS: The most consistent findings across countries were found for the significant associations between neighbourhood social environment and MVPA in both boys and girls. Significant associations with the physical environment varied more between countries and by gender. The most consistent negative associations with ST were found for the social environmental variable of having parental rules for spending time outside the home. CONCLUSIONS: The present findings provided evidence for the generalisability of the associations between environmental correlates and MVPA across four European countries. The findings show clear differences in correlates for MVPA and ST. Further research is needed to better understand the unique aspects of the social and physical environment which explain each of the two behaviours.
