Purpose: The objective of this study was to examine how adolescents' physical activity (PA) changed during the COVID-19 crisis according to level of intensity and whether there are typologies of resilience based on individual and environmental characteristics. Methods: A longitudinal follow-up study of PA in a representative sample of French adolescents (n=808, 16.32±1.01 years old) was carried out. Two online surveys collecting reported data on amounts of PA were completed the week before and during the first week of the lockdown. Data related to individual and environmental characteristics were collected. A principal component method with qualitative and quantitative data (FAMD) for cluster analysis was performed to identify adolescent’s profiles according to their individual, interpersonal and environmental determinants. Two-way repeated measures ANOVA and a Bonferroni Post-Hoc test were performed to detect any significant effects of adolescents’ clusters on time and each intensity level of PA. Results: Three clusters were identified and characterized by a multifactorial process: active, studious and rural adolescents (37%) reported a significant increase in their MVPA (+707 Mets·week-1, p<0.05), inactive, underachieving and rural adolescents (32%) reported a stability in their MVPA (0 Mets·week-1, NS) and urban adolescents (31%) reported a significant decrease of MVPA (-237 Mets·week-1, p<0.05). Conclusion: This study investigated the multifactorial and temporal complexity of PA resilience according to a socio-ecological anchoring, suggesting that factors of resilience in PA are linked to availability of rural and green environments (environmental determinants), good pedagogical follow up (interpersonal determinant) and high initial involvement in PA (individual determinant).
Following increased interest in physical literacy (PL), development of appropriate tools for assessment has become an important next step for its operationalization. To forward the development of such tools, the objective of this study was to build the foundations of the Évaluation de La LIttératie Physique (ELIP): designed to help reduce existing tensions in approaches to PL assessment resulting in a low uptake in applied settings. We followed two steps: (1) the development of the first version of ELIP by deploying a Delphi method (n=30); and (2) the modification of items through cognitive interviews with emerging adults (n=32).The expert consensus highlighted four dimensions of PL to be assessed -physical; affective; cognitive; and social -with new perspectives, including a preference for broad motor tests over fitness. Results offer new insights into the assessment of emerging adults' PL but ELIP still requires further work concerning validity, reliability, and sensitivity.
Background Following an ecological framework, the aim of this study was to highlight the way adolescents invested their time in opportunities to engage in moderate to vigorous physical activity (MVPA) according to whether they were profiled as more or less active. This study’s innovation lies in the analysis of MVPA according to social occasions which are understood as opportunities to be active throughout the day (e.g. home, school, transport). Methods PA data measured by accelerometry (ActiGraph GT3X) for seven consecutive days were compiled, with adolescents’ social occasions during the week recorded in a daily digital diary (n = 135). The opportunity ratio of MVPA at each social time is the ratio between time spent in MVPA and the duration of a corresponding social occasion. Following the literature, participants were categorised into three profiles according to their reported amount of MVPA: HEPA active, minimally active and inactive. Non-parametric Wilcoxon signed rank and Kruskal Wallis tests were performed to determine the relative intensity of PA performed at different social occasions, and to investigate whether intensities differed between adolescents with various activity profiles. Results Results showed that engagement in MVPA at different social occasions differed according to participant profiles. Mismatch was noticed between the opportunity ratio and the duration of the most and least favorable social occasions for MVPA. For all three profiles, the social occasion “physical education lesson” revealed an opportunity ratio of MVPA (23.6% vs 17.0% vs 13.8%) significantly higher than the overall opportunity ratio of the week (6.9% vs 2.9% vs 1.2%), but of lower duration. Conversely, “home” (5.3% vs 0.0% vs 0.0%) and “school” (outside of PE time) (2.4% vs 0.0% vs 0.0%) represented the two least opportune social occasions for PA in an adolescent’s week. Conclusions Rethinking engagement with MVPA in the context of temporal opportunities would allow potential ways to intervene within an educational supervised setting to help young people adopt a physically active lifestyle at the end of the key period of adolescence. These results reinforced the importance of context in interventions for PA promotion, opening for “time education” in people.
