Actual and Perceived Motor Competence in Chilean Schoolchildren before and after COVID-19 Lockdowns: A Cohort Comparison.

Abstract

(1) Background: the measures applied in Chile to reduce COVID-19 infections have been very strict, mainly for children who have experienced lockdowns and school closures for almost two years. Emerging evidence indicates that lockdowns have had several negative effects on children; therefore, the present study seeks to analyze the secular effects of COVID-19 lockdowns on Chilean students' actual motor competence (AMC) and perceived motor competence (PMC). (2) Methods: using a sequential cohort design, data from 523 fifth-grade students at nine elementary schools (46.8% girls, age M = 11.11, SD = 0.66) were assessed in 2018-19 (pre-lockdown) (n = 265) and 2022 (post-lockdown) (n = 258). (3) Results: in the domain of object control (AMC and PMC), no significant differences were found (AMC p = 0.559; PMC p = 0.682). In the self-movement domain of AMC and PMC, the significant differences found presented a small effect size (AMC p = 0.044, ηp2 = 0.01; PMC p = 0.001, ηp2 = 0.03). (4) Conclusions: although the differences encountered were not drastic, self-movement skills tended to be greatly affected by the lockdowns resulting from the COVID-19 pandemic. These findings broaden information on the negative consequences of the pandemic on students in aspects related to an active and healthy life.
