“…MI is a multidimensional construct that can be understood in terms of who or what leads PA experiences (e.g., a teacher, student, and technology); what strategies are used to promote movement opportunities (e.g., teaching academic content with integrated PA, integrating activity breaks between academic lessons, and using special equipment such as pedal desks); the nature and extent to which movement is integrated into classroom routines (e.g., when MI is used and how frequently movement opportunities are provided); and the resources used to develop, structure, and guide MI (e.g., pre-packaged materials, curricula, and programs) [ 13 , 14 ]. Concerning MI resources, a wide variety of MI products have been created and tested in the context of interventions designed to increase teachers’ use of MI and children’s PA but studies report relatively low implementation of MI by classroom teachers [ 15 , 16 , 17 , 18 , 19 ].…”
