however, Covid-19 pandemia are finished, but it is necessary to investigate different effects of this disease. The present study aimed to determine the impact of the limitations imposed by the mandatory quarantine due to COVID-19 on the motor competence of Iranian children.

This research employed a Comparative reason design with a two-stage assessment, including pre and post time of COVID lockdown. The sample consisted of 315 volunteer students (aged 7 to 10) from boys' and girls' elementary schools in Yazd city, Iran. Motor competence assessment (MCA) was conducted using the Loe et al. method. Data analysis involved a 2x2 repeated measures analysis of variance (ANOVA). SPSS version 21 and Excel 2016 were used for all analyses, graphing, and statistical tables. A significance level of 0.05 was considered for all statistical tests.

The results indicated a significant decrease in motor competence and its subscales among Iranian children following the COVID-19-related restrictions (p<0.001).

Based on the findings, it seems that the recommendations of physical activity and exercise for children in quarantine conditions have not been implemented well, and the motor skills have decreased after the imposition of mandatory restrictions, so it is recommended that the authorities pay more attention in this regard. and develop and implement appropriate programs to improve it.
