The health benefits of a physical active lifestyle and physical fitness from a young age are widely recognized as beneficial. This study examined the relationship between physical fitness and motor competence in children aged four- to six-years-old. A sample of 42 children (mean age 5.15 years, SD 0.56 year) participated in the study. To assess motor competence, each child completed the Movement Assessment Battery for Children (MABC). Physical fitness was measured by the Test of Physical Fitness (TPF), comprising nine different tasks including running, jumping, throwing and climbing. The results show a strong and significant correlation between motor competence and physical fitness within the sample (r = -0.614). Preschooler's engagement in physical active play may explain the strong correlation between the two variables, as this type of activity will give more opportunity to increase fitness and to gain experience and practice which influences the rate and direction of motor development. Young children should have access to activities and environments that promote an active lifestyle.
