Compulsory physical education classes appear to be the cornerstone for motivating students committing to an active lifestyle. However, an essential condition must be met if physical education (PE) is to fulfill this essential mission: students must have fun. While the recent literature agrees that enjoyment is a lever of physical activity, it differs on how to define the concept: declared motivation or embodied enjoyment, and therefore how to measure it. Considering with Booth (2009) enjoyment as an exceedingly complex concept, we will envision it here in terms of valence (hedonic tone) and activation (physical activity).So, what pedagogical conditions must be in place for students to be motivated and more physically engaged in sport at school? The purpose of this study was to estimate the effect of practice formats on the enjoyment experienced and the amount of physical activity of physical education students. The participants included 44 students (Mage = 13.92, SD = 2.35, 64% male, range 11-19) enrolled in three badminton tasks. We designed each task by a specific emotional focus.In the first type of task, the feeling experienced is domination or frustration because the main goal is individual victory. In the second one, designed to promote meeting, the type of emotion experienced is conviviality and cooperation because the main goal is a collective victory. In the third type of task, designed to promote personal challenge, the type of emotion experienced is transcendence. We measured students' engagement in terms of enjoyment stated (using an approved ten-item scale) and PA level using Actigraph GT3X accelerometers. Results indicated no effect of task design on the pupils’ enjoyment but showed a significant difference in terms of P.A. This confirmed that the measurement of pleasure is complex. Indeed, students (especially young males)movedmore in the meeting task than in the challenge task (p < .05., ES = .43). From a PA promotion perspective in PE, meeting tasks appeared to be a better way of testing the quantity of movement than challenge tasks in badminton.
