Physical activity is essential to child development, but studies show that children are
increasingly inactive. Due to schools being considered privileged environments to promote physical
activity, the aim of this study was to increase the physical activity performed by early childhood
education children during the school day by integrating movement into academic content and
analyze this process. The amount and intensity of physical activity performed by a group of 24
3–4-year-old children in three different weeks were measured by accelerometry: one week with the
methodology they had been following (week 1); and two weeks in which movement was integrated
into the content through a specific proposal (week 2) and the same improved proposal (week 3). The
results reveal that the application of a movement integration program not only allowed students to
work on academic content in a physically active way, but also significantly increased the amount of
physical activity that children performed during the school day. However, it was necessary to carry
out several interventions the same day, or make movement integration the reference methodology, to
meet the minimum recommended physical activity levels. In addition, to increase their effectiveness,
interventions should be continually reviewed and improved to increase the motor engagement time.
