This study examined the effects of a motor-skill intervention on children’s perceived motor competence (PMC; object control, locomotor, and combined [total]) and explored if effects differed between the sexes. Preschoolers (N = 274; 47.96 months) completed either a motor-skill intervention (the Children’s Health Activity Motor Program [CHAMP]) or recess. PMC was measured with the Digital Scale of PMC before and after each condition. Controlling for pretest scores, recess girls had lower posttest object-control PMC scores than CHAMP boys, CHAMP girls, and recess boys (all p < .05). CHAMP children had significantly higher posttest locomotor and total PMC (all p < .001) compared with children who engaged in recess. CHAMP partially eliminates sex differences in PMC, particularly for object-control skills. Girls who participated in recess did not increase PMC like children in CHAMP and boys who engaged in outdoor recess.

这项研究检验了运动技能干预对儿童感知运动能力（PMC；对象控制、运动和综合[总计]）的影响，并探讨了性别之间的影响是否存在差异。学龄前儿童（N  = 274；47.96 个月）完成了运动技能干预（儿童健康活动运动计划 [CHAMP]）或课间休息。在每种条件之前和之后用PMC数字标尺测量PMC。控制预测分数后，课间女生的后测对象控制 PMC 评分低于 CHAMP 男生、CHAMP 女生和课间男生（所有p  < .05）。 与休息的儿童相比，CHAMP 儿童的测试后运动能力和总 PMC 显着更高（所有p < .001）。CHAMP 部分消除了 PMC 中的性别差异，特别是在对象控制技能方面。参加课间休息的女孩并没有像 CHAMP 中的孩子和参加户外课间休息的男孩那样增加 PMC。
