Background/objectives: Children participate in various organized and informal physical activities (PAs) in their leisure time, presenting diverse objectives and environments for motor and social development. However, current research often focuses on specific, mostly organized activities, overlooking the complexity of participation across different settings. This study aimed to (1) identify groups of children with similar characteristics based on their participation in five organized and informal sports activities and (2) examine how the groups differ regarding gender, age, BMI, motor competencies (MCs), and attendance in institutionalized care at school.
Methods: The study included n = 1717 1st and 2nd graders (M = 7.60 years, SD = 0.59, 50.7% girls) and n = 1319 3rd and 4th graders (M = 9.46 years, SD = 0.57, 49.4% girls) from the "EMOKK" study, funded by the Swiss National Science Foundation. Data were collected via parent questionnaires on leisure sports participation, and MCs were assessed using MOBAK-1-2 and 3-4 tests. Latent profile analyses (LPAs) and univariate ANOVAs were used to identify group differences.
Results: A three-profile LPA model best fits the data, revealing differences in participation across individual and team sports, optional school sports, free play on the school playground, and informal activities during leisure time. Children involved more in team sports (profiles: allrounder and very active sportsperson) participate more in informal play and present better MCs than children participating mainly in individual sports (profile: individual sportsperson). Girls were predominantly in the individual sports profile, while boys were more evenly spread across all groups. These findings highlight the importance of designing targeted interventions that promote participation in both organized and informal sports, particularly for children with lower levels of PA.
Conclusions: Children show different patterns of engagement in different interrelated organized and informal leisure PA contexts. These specific patterns and the children's MCs should be taken into account for the targeted promotion of PAs during leisure time.
