Abstract

This study (a) examined the associations among different performance metrics derived from different strategies (i.e., maximum and average scores) and trials from product-oriented measures of motor skills, and (b) explored how different performance metrics from product-oriented assessments of motor skills change in young children with typical development. Children ( N = 279; 156 girls; M age = 4.44 years) completed a battery of product-oriented assessments for throwing (in meters per second, five trials); kicking (in meters per second, five trials); jumping (in centimeters, five trials); running (in meters per second, two trials); and hopping (in meters per second, four trials—two preferred foot, two nonpreferred foot). A total of 36 performance metrics were derived—throw ( n = 7), kick ( n = 7), jump ( n = 7), run ( n = 4), and hop ( n = 11). Intraclass correlations examined reliability among performance metrics for each skill; linear mixed models examined whether variations changed across early childhood. There was excellent reliability among all performance metrics for each skill (all ICC > .90). Linear mixed models revealed that children’s motor performance improved for two metrics of the throw, five variations of the jump, and three metrics of the hop (all p < .05). Researchers should be aware that some performance metrics from product-oriented assessments (e.g., maximum and average of three or five trials) are highly related and change, whereas others do not.
以产品为导向的基本运动技能的绩效指标——比较与发展的视角
本研究(a)考察了不同策略(即最高分和平均分)和以产品为导向的运动技能测量试验得出的不同表现指标之间的关联,(b)探讨了典型发展幼儿运动技能的不同表现指标是如何从以产品为导向的评估中变化的。儿童(N = 279;156个女孩;(年龄= 4.44岁)完成了一系列以产品为导向的投掷评估(以米每秒为单位,五次试验);踢腿(米/秒,5次);跳远(以厘米为单位,5次);跑步(以米/秒为单位,两次试验);还有跳跃(以米每秒为单位,四次试验——两次首选脚,两次非首选脚)。总共得到了36个性能指标——投掷(n = 7)、踢(n = 7)、跳跃(n = 7)、跑(n = 4)和跳(n = 11)。班级内相关性检验了每项技能绩效指标之间的可靠性;线性混合模型检验了儿童早期是否会发生变化。每项技能的所有绩效指标(所有ICC >.90)。线性混合模型显示,儿童的运动表现在投掷的两个指标、跳跃的五个变化和跳跃的三个指标上都有所改善(p <. 05)。研究人员应该意识到,以产品为导向的评估中的一些绩效指标(例如,三次或五次试验的最大值和平均值)是高度相关的,并且会发生变化,而其他指标则不会。

期刊介绍: The Journal of Motor Learning and Development (JMLD) publishes peer-reviewed research that advances the understanding of movement skill acquisition and expression across the lifespan. JMLD aims to provide a platform for theoretical, translational, applied, and innovative research related to factors that influence the learning or re-learning of skills in individuals with various movement-relevant abilities and disabilities.
