Motifs de la pratique de l'activite physique associes a differents types d'activites physiques chez les eleves de la 5e et 6e annee.

摘要

BACKGROUND: There is a critical need for physical activity programs, but most interventions are not effective in increasing physical activity levels in youth. Existing interventions focus on general physical activity levels, and not on specific types of physical activities. However, physical activity practices are not necessarily stable among youth and preferences tend to vary over time. Understanding what physical activity goals motivate youth to engage in different types of physical activities could inform the design of more specific, and potentially more effective, interventions. The overall objective of this study was to explore the relationship between different physical activity goals and types of physical activities practiced by youth according to the Self-Determination theory. Specifically, we wished to 1) Identify physical activity goals associated with participation in physical activities that are organized, non-organized, group-based and individual, and 2) Identify physical activity goals that are associated with achieving current physical activity recommendations. METHODS: We conducted a cross-sectional analysis based on data from the MATCH study ( Measuring the physical Activities of Teenagers to Comprehend their Habits). Eight hundred and two grade 5 and 6 students from 17 schools in New-Brunswick completed a questionnaire regarding their participation in different types of physical activity, their physical activity goals and attainment of physical activity guidelines. Relationships between goals and participation in different types of physical activities as well as attainment of physical activity recommendations were assessed using multilevel logistic regression models. RESULTS: Goals distinguishing participants from non-participants varied within each type of physical activity. Odds of practicing organized physical activity were higher among students motivated by enjoyment goals and lower among those motivated by social goals. Higher competence goals were associated with greater odds of participating in group-based physical activity and achievement of physical activity recommendations. CONCLUSION: Targeting intrinsic physical activity goals such as enjoyment and competence in interventions for youth may increase participation in organized and group-based physical activities, as well as help improve the likelihood of meeting physical activity guidelines.;Keywords: Physical activity, motivation, Self-Determination Theory,
