Performance Metrics From Product-Oriented Measures of Fundamental Motor Skills—A Comparison and Developmental Perspective

Le résumé fourni par la source

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; Mage = 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.
