The Role of Physical Activity in Post-COVID Schoolchildren’s Motor Competence

<b>Background:</b> Motor competence (MC) is closely linked to children's physical activity (PA) levels, playing a critical role in their overall health and development. <b>Purpose:</b> This study explores the relationship between MC and PA among elementary school-aged children in northern Brazil. <b>Study Sample:</b> 261 children (52.11% boys and 47.89% girls) aged 5-14 (9.62 ± 2.70 years; 18.25 ± 3.92 Kg/m²). <b>Data Collection:</b> public and private schools in northern Brazil. <b>Research Design:</b> MC was assessed using the Motor Competence Assessment tool, and the PA levels were determined using the International Physical Activity Questionnaire (IPAQ) in its abbreviated form. <b>Results:</b> Most children (66.7%) were classified as physically active, with 27.2% showing very low levels of MC, and boys also outperformed girls. General results showed a moderate association between age and BMI (r = .402; <i>p</i> < .05), and a weak negative association between MC and BMI (r = - 0.177; <i>p</i> < .05). Also, a significant negative correlation was observed between BMI and MC in girls (r = -.361; <i>p</i> < .05). Multinomial regression analysis indicated that manipulative skills and overall MC significantly predicted higher PA levels. Higher levels of MC and increasing age were associated with greater PA and reduced odds of being irregularly active. <b>Conclusions:</b> These findings highlight the importance of early intervention, suggesting that enhancing MC can be a key strategy for promoting children's health and fostering active lifestyles. In particular, the post-pandemic context reinforces MC as a critical factor influencing PA levels in children.
