Active break intervention
SECONDARY
AB intervention takes place daily and is carried out in the normal academic lessons, where two ABs per day are included in the 7th and 8th grade timetable of each secondary school. The timing of the AB is coordinated with the school management team. Whenever possible, one AB is scheduled before recess and the other after recess. It is important to note that no AB are scheduled during physical education classes or the lesson immediately following physical education. This ensures that the effect of the AB is not solely attributed to the PA performed in the preceding physical education class. The remaining class time follows the usual methodology without any variation.The implementation of this intervention utilizes digital platform accessible to schools through individuals’ usernames and passwords. This platform has been specifically designed to facilitate the development of AB in school classes. An example of AB can be found in the following link: Teachers have access to the platform and are responsible for conducting the AB as scheduled by the research team. During the AB, students follow the instructions provided by an avatar that guides the session through the platform. To ensure the proper use of the platform, the research team provides training and support to the teachers. During the initial phase of the intervention, the research team accompanies the teachers for the first 2 weeks to ensure a smooth implementation of the AB and address any questions or concerns that may arise. This support aims to familiarize the teachers with the platform and ensure they feel confident in delivering the AB effectively.
