To measure motor competence among a representative sample of Iranians aged 5-85 years.
Cross-sectional.
Motor competence was assessed quantitatively by the Test of Motor Competence; two fine motor skills (placing and building bricks) and two gross motor skills (heel-to-toe-walking and walking/running in slopes) to assess dynamic balance. Task scores were summed and transformed into standardized scores (z-scores). Data were stratified by 12 chronological age groups and sex.
Participants were 500 Iranians aged 5-85 years (females = 64%, age 5-35 years = 82%). There were significant age differences in motor competence and the distribution between age and z-score distribution was u-shaped. Between childhood and adolescence there was a rapid improvement in motor competence with maximal speed (-2 standard deviations) occurring among 19-25-year-olds. For each decade after age 25 years, z-scores progressively decreased approximately 1 standard deviations until age ≥56 years when performance decreased to approximately the same speeds as children (> +3 standard deviations). Sex differences were observed between children and adolescents.
The sample characteristics constrain the generalizability of our findings. The Test of Motor Competence is easy to administer, uses a standardized test battery for people aged 5-85 years, and the quantitative outcome enables longitudinal monitoring of motor competence across the life course. As life expectancy and the proportion of populations aged >65 years increases, understanding how to maintain health in older age is an important public health issue in 21st century.
测量伊朗代表性年龄在 5-85 岁人群的运动能力。
横断面研究。
运动能力通过运动能力测试进行定量评估；通过两个精细运动技能（放置和搭建积木）和两个大运动技能（脚跟到脚趾行走和在斜坡上行走/跑步）来评估动态平衡。将任务得分相加并转换为标准化得分（z 分数）。数据按 12 个年龄组和性别分层。
参与者为 500 名伊朗人，年龄为 5-85 岁（女性占 64%，5-35 岁年龄组占 82%）。运动能力存在显著的年龄差异，年龄与 z 分数分布之间的关系呈 U 形。在儿童期和青春期之间，运动能力迅速提高，最快速度出现在 19-25 岁之间（-2 个标准差）。在 25 岁以后的每个十年中，z 分数逐渐降低约 1 个标准差，直到 56 岁以上时，表现速度降至与儿童相似（>+3 个标准差）。在儿童和青少年之间观察到性别差异。
样本特征限制了我们研究结果的普遍性。运动能力测试易于实施，适用于 5-85 岁人群，使用标准化测试组合，其定量结果能够在整个生命周期内监测运动能力的纵向变化。随着预期寿命和 65 岁以上人口比例的增加，了解如何在老年时保持健康是 21 世纪的一个重要公共卫生问题。
