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 10 at high intensity (85-90% of HR max) followed by 20 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. To increase the workload, and after evaluation of cardiorespiratory capacity, after 12 weeks of program, the HIIT protocol will be changed to 20 of high intensity work alternating with 10 of recovery."
