The evolution of the MOVI studies, conducted by the research group, has led to create the last project (MOVI-HIIT; ClinicalTrials.gov Identifier: NCT04863040).~This pilot study will include children aged 4-6 years from 2 public schools of the province of Ciudad Real, Spain, with 2 arms (intervention and control) and the intervention will last 8 weeks.~The intervention proposed in the study is implemented through an online platform developed to achieved the intensities required for the age-range of participants, but this platform has never been tested accurately in the classroom.~Thus, it seems necessary to pilot the intervention to evaluate the acceptability and feasibility of the intervention, in order to improve facts, if necessary, to achieved proposed objectives.
Pilot study to test the acceptability and feasibility of an intervention aimed to test the effectiveness, in preschool children, of an integrated physical activity intervention in the classroom based on intervallic training (MOVI-HIIT) on improving executive function, body composition and cardiorespiratory fitness.
