The MOVI-HIIT Pilot Trial: The Impact of Activity Breaks on Cognitive Function, Adiposity and Fitness in Preschoolers

"Each HIIT break will last approximately 5 minutes and will not require any specific materials. The structure of the HIIT-Rest will be as follows: 1' to describe the work to be done; 3' of work following the HIIT protocol: 6 repetitions of a functional movement such as squats, Jumping Jack or running on site for 20 at high intensity (85-90% of HR -heart rate- max) followed by 10 of recovery (65-75% of HR max); and 1' to perform a return to calm in order to lower the activation and prepare the student body to return to class activities."
