Despite significant advances in the knowledge and understanding of associations between the phenomenon of excess body weight (hereafter “overweightness”) and fundamental movement skill (FMS) proficiency, the question of how overweightness affects critical features of movement remains unanswered. This study examined the differences in the proficiency of FMS between boys and girls with different weight status on the level of critical features. Three hundred and twenty-two boys and girls aged 5 to 10 years were assessed in eight FMS (run, vertical jump, long jump, ball catch, ball kick, ball pass, ball bounce, and forehand strike) and were assigned to non-overweight and overweight groups according to their waist-to-height ratio, with a cut-off point of 0.5. FMS score differences (p < 0.05) between boys and girls that can be frequently observed in the non-overweight group of children were not determined in the overweight group of children (p ≥ 0.131). Overweight boys performed worse in a higher number of skills’ critical features than overweight girls did when compared to non-overweight groups. With weight gain, boys might experience a more significant decline in FMS proficiency than girls do because of the higher scores when non-overweight. The critical features of FMS indicate that overweightness might affect postural control and coordination, which this paper discusses.

影响幼儿基本运动技能关键特征的因素

尽管在超重现象（以下称“超重”）与基本运动技能（FMS）水平之间的关联的认识和理解方面有了长足的进步，但超重如何影响运动关键特征的问题仍未得到解答。这项研究检查了不同体重状态的男孩和女孩在FMS熟练程度方面的关键特征水平的差异。在8个FMS中对322个5至10岁的男孩和女孩进行了评估（奔跑，垂直跳跃，跳远，接球，踢脚，传球，弹跳和正手打击），并分配给非超重和超重人群的腰高比例，截止点为0.5。FMS分数差异（p <0。05）在非超重儿童组中经常观察到的男孩和女孩之间的差异未在超重儿童组中确定（p≥0.131）。与非超重组相比，超重男孩在技能的关键特征上表现较差的女孩差得多。随着体重增加，男孩的FMS熟练度下降可能比女孩大得多，这是因为非超重时得分较高。FMS的关键特征表明，超重可能会影响姿势控制和协调，本文将对此进行讨论。随着体重增加，男孩的FMS熟练度下降可能比女孩大得多，这是因为非超重时得分较高。FMS的关键特征表明，超重可能会影响姿势控制和协调，本文将对此进行讨论。随着体重增加，男孩的FMS熟练度下降可能比女孩大得多，这是因为非超重时得分较高。FMS的关键特征表明，超重可能会影响姿势控制和协调，本文将对此进行讨论。
