Relation entre la proximité à des infrastructures récréatives et le maintien des pratiques d’activités physiques organisées et non-organisées lors de la transition entre l’enfance et l’adolescence / Relationships between proximity to physical activity infrastructures and maintenance of organized and unorganized physical activities in youth

Mackenzie, Jason January 2015 (has links)
Résumé : Introduction : Les infrastructures récréatives telles que les parcs et les pistes cyclables peuvent fournir des opportunités pour pratiquer l’activité physique (AP). Comme les déterminants de l’AP organisée et non-organisée (APO et APNO) pourraient différer, nous avons investigués si la proximité à des infrastructures récréatives est associée avec le maintien de la participation à l’APO et à l’APNO sur une durée de trois ans lors de la transition entre l’enfance et l’adolescence. Méthodes : 187 jeunes, initialement âgées de 10 à 12 ans, ont rapporté leur participation à l’APO et l’APNO trois fois par an pendant trois ans pour un total de neuf cycles d’observations. Les données sur la proximité des infrastructures récréatives ont été obtenues par le biais de questionnaires téléphoniques auprès des parents. Les scores de proximité ont été divisés en tertiles. Des analyses Kaplan-Meier et des modèles de risques proportionnels de Cox ont été utilisés pour estimer les associations univariées et multivariées entre la proximité aux infrastructures récréatives et le nombre de cycles moyen dans lequel l’APO et l’APNO a été maintenu. Résultats : Aucune différence, brute ou ajustée, de la durée moyenne du maintien de la participation à l’APO [nombre de cycles d’observation moyen (intervalle de confiance 95%) était 6.6 (5.7, 7.5), 6.3 (5.5, 7.1), et 5.8 (5.1, 6.6)] et à l’APNO [6.8 (6.2, 7.4), 5.9 (5.3, 6.5), 6.6 (5.9, 7.3)] a été observée entre les tertiles de proximités bas, moyen et haut, respectivement. Conclusion : Les résultats suggèrent que la proximité aux infrastructures récréatives n’influence pas le maintien de l’APO et de l’APNO lors de la transition entre l’enfance et l’adolescence. D’autres aspects de l’environnement physique pourraient avoir un effet sur le maintien de l’APO et de l’APNO. / Abstract : Background: Physical activity (PA) infrastructures such as parks and cycle lanes can provide youth opportunities to engage in physical activity. As the determinants of organized and unorganized PA (OPA and UPA) are likely to differ, we investigated if proximity to PA infrastructure was associated with maintenance of participation in OPA and UPA over 3 years during the transition from childhood to adolescence. Methods: Youth (n=187) initially 10-12 years self-reported participation in OPA and UPA at 4 month intervals over 3 years for a total of nine survey cycles. Data on proximity to PA infrastructures was obtained from parents through phone-based questionnaires. Proximity scores were divided into tertiles. Kaplan-Meier and Cox proportional hazard models were used to assess univariate and multivariate associations between proximity to PA infrastructure and number of cycles in which OPA and UPA were maintained. Results: There were no crude or adjusted differences in average duration of maintenance of participation in OPA [mean number of survey cycle participation (95% confidence interval) was 6.6 (5.7, 7.5), 6.3 (5.5, 7.1), and 5.8 (5.1, 6.6)] and UPA [6.8 (6.2, 7.4), 5.9 (5.3, 6.5), 6.6 (5.9, 7.3)] across low, moderate and high tertiles of proximity to PA infrastructure scores, respectively. Conclusion: Findings are suggestive that proximity to PA infrastructure alone does not affect maintenance of participation in OPA or UPA during adolescence. Other aspects of the environment may have a greater effect. Thus, further research is needed on these aspects before firm conclusions can be drawn.

Pohybová aktivita žen pravidelně sportujících. / Physical activity of women with regular participation in sport activities.

Schubertová, Monika January 2012 (has links)
The issue: The issue of lack of physical activity refers to as the population of children and youth, as well as the adult population. Properly chosen and regularly performed sports games in terms of health may make recommendations of physical activity sufficient. This thesis deals with the physical activity of the adult population of women with regular physical activity. Objectives: The aim is to determine the amount of physical activity in the adult population of women with regular organized physical activity, and the results of comparison with older school-age girls without regular organized physical activity. At the same time to relate the observed results to health physical activity recommendations. Tasks and Methodology: Physical activity is detected using accelerometers ActiGraph GT3X supplemented the written record and physical activity. Results: The result of the study confirmed our hypothesis. The women with regular organised physical activity reported significantly higher energy expenditure peer week, work days and weekend days in comparison with without organised physical activity. Women with regular organised physical activity met the health physical activity recommendations in six days from all seven days of measuring. Older school-aged girls met the health physical activity...
