movement behaviors
The present pilot work evaluates the effects of a novel, one-month educational intervention (the Globe Trotter Initiative), aiming to simultaneously engage primary school children in an activity-based game while increasing knowledge of the health effects of PA and sedentary behavior though targeted educational sessions as well as classical academic lessons integrating healthy behaviors as teaching materials.The results of the present analysis show that the Globe Trotter Initiative that combined educational sessions, a gaming context, and the use of topic-specific material as academic teaching support seem effective in reducing primary school children’s sedentary time as well as increasing their preferences for physical activities over sedentary behaviors.The present results seem particularly promising, indicating that a one-month school-based intervention might be able to reduce sedentary time in primary-school-aged children. Importantly, these results were reinforced in the present work by a reduction in children’s implicit preference for sedentary activities, with an increasing preference for PA over time.Our results are the first to provide such evidence regarding the ability to change the implicit preference for movement behaviors, based on a validated and reliable computerized behavioral task [Interestingly, our results also indicate that those with higher baseline levels of sedentary behavior were associated with greater changes in sedentary time over the intervention, suggesting a greater effect on the kids initially presenting a high time dedicated to sedentary behaviors, which is encouraging. This highlights once more the need to consider children’s initial behavioral profile to propose more individualized and effective interventions [The present results must be interpreted in light of some limitations. Despite the strength of the sample size and the use of objective field testing to evaluate the children’s physical fitness, the use of a self-reported questionnaire to assess PA and sedentary behaviors may be considered a limitation. However, the CAPAS-Q was recently found reliable and reproducible in this population, validated against objective accelerometer-based measurements [
