2.2.2. Implementation of the Program into Schools
sedentary behaviors
First, the schoolteachers completed a one-day training led by experts from the JDB Foundation before the beginning of the game in order to equip them with different tools to be used and how to handle the game. Importantly, the involved teachers, with the help of the investigation and implementation team, proposed content and materials that included the plans, benefits, and disadvantages of PA and sedentary behaviors within their classical academic lessons. Indeed, not just physical education teachers and classes were involved, but all disciplines included in the school curricula were considered (e.g., mathematical or biology lessons included PA and sedentary behavior examples). A member of the JDB foundation remained available to help teachers at any time during the game.
