Childhood obesity is a public health problem that affects many parts of the world, and is one of the factors that has negatively influenced levels of motor competence at an early age. However, these relationships remain poorly investigated. The aim of this study was to assess body composition (BC) and motor competence (MC), as well as to study their relationship with school performance in primary school children in Portugal. A quantitative study was carried out with a sample of 272 children aged between 6 and 10 years old, divided into 4 years of schooling. The Motor Competence Assessment was used to assess motor competence (MC) and a bioimpedance scale (InBody) was used to assess body composition (BC). The results showed that, with the exception of 1st year, all the children were overweight and this worsened as the school year progressed. As for motor competence, it increases as the children grow, but at low levels for their age, with only the 3rd and 4th years showing a relationship between MC and BC. The results also showed a positive relationship between academic achievement and MC only in the 4th year of schooling. These results highlight the need for intervention in primary schools to combat childhood obesity and motor illiteracy, as well as demonstrating that the better children's MC, the better their school performance.
儿童肥胖是一个影响世界许多地区的公共卫生问题，并且是对儿童早期运动能力水平产生负面影响的因素之一。然而，这些关系仍未得到充分研究。本研究的目的是评估身体成分（BC）和运动能力（MC），并研究它们与葡萄牙小学生学业成绩之间的关系。对272名6至10岁的儿童样本进行了一项定量研究，这些儿童分为4个学年。使用运动能力评估来评估运动能力（MC），并使用生物电阻抗秤（InBody）来评估身体成分（BC）。结果表明，除了一年级外，所有儿童都超重，并且随着学年的推进情况恶化。至于运动能力，它随着儿童的成长而提高，但相对于他们的年龄处于较低水平，只有三年级和四年级显示出MC与BC之间的关系。结果还表明，学业成绩与MC之间仅在四年级呈正相关。这些结果凸显了在小学进行干预以对抗儿童肥胖和运动能力不足的必要性，同时也表明儿童的MC越好，他们的学业成绩就越好。
