Abstract

Motor commitment time (MCT) has relevant implications in the Physical Education class, since it is related to the regular physical activity that a child or adolescent should perform and the suggestions of international organizations in relation to the minimum amount required for the maintenance of health. The aim of this work is to analyze the engagement motor time in physical education classes in primary education through a systematic review. The search was made in Web of Science, Scopus, ERIC and Dialnet, selecting articles published between 2009 and the first semester of 2021. Applying inclusion and exclusion criteria, eight articles were selected, comprising a study population of 1262 students. The MCT is low in the classes observed, and moderate to vigorous physical activity presents declining data. In the study with the best result, the MCT reaches 46.67 % and, in the remaining studies, 43.44 %, 42.8 %, 41.45 %, 32 %, 31.5 %, 28.53 % and 18.10 %. Boys achieve higher MCT than girls; boys and girls in the early ages achieve higher participation and have more physical activity; the morning schedule and some didactic units favor a higher MCT. It was found that the MCT is low in Physical Education classes, and that time management in the class conditions the magnitude of the physical activity carried out by boys and girls. The motor engagement time achieved in the class is insufficient to cover the minimum suggestions for physical activity in the school period.
