Move Kids-24h Physical Education Program

Introduction: The development of fundamental movement skills (FMS) is essential to acquiring the necessary skills that allow children to be competent in several sports, games and dances. Competence is acquired from FMS skills through practice and experiences during childhood. However, evidence from previous studies showed low levels of FMS, given that 4.4% of the preschoolers were delayed in gross motor skills, and 8.8% were at risk of delay. Aim: To evaluate the effects of a structured physical education (PE) program on preschoolers' FMS, implemented and delivered by PE teachers. Secondary aims are to evaluate the effects of the physical education program on (i) preschoolers' movement behaviors, (ii) physical fitness levels, and (iii) blood pressure. Methods: Cluster randomized controlled trial study. Sample: 40 preschool children, aged 3 to 4 years old. Primary Outcomes are FMS, assessed with the Test of Gross Motor Development- Third Edition. Secondary outcomes are physical activity (PA), physical fitness, blood pressure and Body Mass Index (BMI). Expected results: Participation in the PE program will likely have a positive effect on the development of FMS, potentially increasing PA levels and improving physical fitness. It is also expected that FMS show a consistent positive association with BMI and blood pressure levels. The results of this randomized controlled trial (RCT) have the potential to inform future guidelines for PE classes in Chilean preschoolers and strengthen the scientific knowledge on this type of intervention in this population.
