Effect of Physical Literacy Breaks (PLBreaks) program on physical literacy in Portuguese schoolchildren

Experimental group will carry out the program in the educational centres during break times, 3 times a week, for 3 months. The duration of each session will be between 20 and 30 minutes, according to the time pre-established by each educational centre for the students' breaks. During these sessions, activities will be carried out in which physical activity is practised at the same time as motivation is fostered and knowledge is acquired about healthy lifestyle habits and knowledge about conceptual aspects of physical activity and its benefits. Every session will be divided into two 10-minute blocks. In the first block, activities will be carried out to develop knowledge and understanding of healthy lifestyle habits and active daily behaviours through body expression. For example, students in groups will have to represent ways of moving actively to school, a concept related to Physical Activity (strength, endurance, agility...), a healthy lifestyle habit, a sporting skill,... and their classmates will have to guess their actions. The second block will be based on active play, as play is fundamental in the transmission of values and attitudinal content, also stimulating social and civic relations with others. During the games, basic skills will be developed, such as moving, jumping, spinning or throwing, thus trying to improve them, as well as the motivation of the pupils. The games will have a cooperative as well as a competitive component, due to the motivational benefits this can bring. All session will be supervised by the physical education teacher and a sports sciences professional researcher. The attendance will be checked using a checklist.
