We searched four databases (PubMed, Scopus, Web of Science, and PsycINFO) for cross-sectional, case-control, and cohort studies comparing physical fitness between children with and without DCD. We assessed the methodological quality of the studies with the Newcastle-Ottawa Scale (NOS). We calculated Cohen\'s d effect sizes to provide clinical evidence of group differences in aerobic capacity, anaerobic capacity, muscle strength, body composition and flexibility.
We included 32 studies for qualitative synthesis after applying eligibility criteria. All selected studies ranged from moderate to high research quality. Effect sizes in favor of typically developing children over children with DCD were large for aerobic capacity (d = 1.15), anaerobic capacity (d = 0.90), and muscle strength (d = 0.79), and small for body composition (d = 0.43) and flexibility (d = 0.21) outcomes.
Children with DCD presented significantly lower physical fitness than their typically developing peers, particularly in aerobic and anaerobic capacity and in muscle strength.
■我们搜索了四个数据库(PubMed,Scopus,WebofScience,和PsycINFO)用于横截面,病例控制,和队列研究比较有和没有DCD的儿童的身体素质。我们用纽卡斯尔-渥太华量表(NOS)评估了研究的方法学质量。我们计算了科恩的d效应大小,以提供有氧能力组差异的临床证据,厌氧能力,肌肉力量,身体成分和灵活性。
■在应用合格标准后,我们纳入了32项定性综合研究。所有选定的研究范围从中等到高研究质量。对于有氧能力(d=1.15),有利于典型发育的儿童超过DCD儿童的效应大小较大,厌氧能力(d=0.90),和肌肉力量(d=0.79),和小的身体成分(d=0.43)和灵活性(d=0.21)的结果。
■患有DCD的儿童的身体素质明显低于通常发育中的同龄人,特别是在有氧和无氧能力以及肌肉力量方面。
