Development of vertical and forward jumping skills in typically developing children in the context of referent control of motor actions. Dev Psychobiol 2020; 62:711-722.

Abstract
The empirically based referent control theory of motor actions provides a new framework for understanding locomotor maturation. Mature movement patterns of referent control are characterized by periods of minimization of activity across multiple muscles (global electromyographic [EMG] minima) resulting from transient matching between actual and referent body configurations. We identified whether locomotor maturation in young children was associated with (a) development of referent control and (b) children's frequency of participation in everyday activities evaluated by parents. Kinematics and EMG activity were recorded from typically developing children (n = 15, 3-5 years) and young adults (n = 10, 18-25 years) while walking, vertical or forward jumping. Presence and location of global EMG minima in movement cycles, slopes of ankle vertical/sagittal displacements, and shoulder displacement ratios were evaluated. Children had fewer global EMG minima compared to adults during specific phases of vertical and forward jumps. Ankle displacement profiles for walking and jumping forward were related to each other in adults, whereas those for walking and vertical jumping were related in children. Higher frequency of participation was significantly correlated with more mature jumping patterns in children. A decrease in the number of global EMG minima and changes in ankle movement patterns could be indicators of locomotor immaturity in typically developing children.

Abstract
We assessed the test-retest reliability of the Sargent jump (VJ) for vertical jumping performed by 4 and 5 years old pre-schoolers. The VJ was administered three times (familiarization, test, and retest) to 163 children (mean age: 4.48 ± 0.5 years; 55.8% girls). The results were compared with those obtained in the standing long jump (SLJ) and in the 25 -m dash test to identify how its performance correlated with other measures of leg power. Systematic change in the mean and retest correlations with these other measures were used to help analyze VJ test-retest reliability. Additionally, Pearson correlation coefficients were used to examine the degree of association between the test and retest trials of the VJ. The VJ showed a higher correlation and agreement in the 4-year-old, compared with the 5-year old, group (rc = 0.956 vs. 0.796; α = 0.95 vs. 0.84; ICC: 0.828; 95% CI: 0.730-0.891 vs 0.739; 95% CI: 0.589-0.834). Effect sizes were small ( d ≤ 0.285) for all the VJ tests performed. Fair to poor significant relationships were established between the VJ (test), VJ (retest), and the SLJ. No significant association was observed between the VJ and the 25 -m dash tests. Our findings suggest that the Sargent jump test is reliable when executed by 4- and 5-year-olds. The lack of a strong association with other measures of leg power should be taken into account at the time of selecting the most appropriate test to assess this strength dimension.

Abstract
Imitation is commonly considered as a hierarchical process. The current study explored the reproduction of a multi-task course in deferred imitation. Eighty-five children between 3.5 and 7.5 years old were divided into five groups and instructed to watch a live human adult demonstrator who performed simple successive actions, such as walking, jumping, grasping, carrying objects from one location to another through six sessions. After a five-minute delay, the children were individually instructed to reproduce the course. Their responses were videotaped and coded in dichotomous data at two hierarchical levels, namely goals and their spatial location. The main findings showed no improvement in the replication of goals due either to age or trials. However, there was an improvement in the integration of the goals' spatial location over trials. This signifies that imitation is an active reconstruction mechanism hierarchically organized.

Imitation of a bimanual task in preschool- and school-age children: a hierarchical construction. J Electromyogr Kinesiol 2012; 22:513-9. [PMID: 22391341 DOI: 10.1016/j.jelekin.2012.01.016] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/16/2011] [Revised: 01/30/2012] [Accepted: 01/30/2012] [Indexed: 11/23/2022] Open
Abstract
The present study examined the development of bimanual interaction during the imitation of a live demonstration. To this end, children of five different age groups observed an adult model performing in an object manipulation task consisting to open a box with one hand, taking out an object with the other hand, and closing the box again, before they were asked to imitate this motor task under different imitation conditions. The children's responses were videotaped, coded in dichotomous data, and then transformed in percentage scores. The main results showed that all children were able to imitate/attain the goal of the task. However, differences were observed for the different imitation conditions, which were also reflected in some age effects, while hand dominance was a strong constraint on imitation. Also, practice did not seem to increase the likelihood of model imitation. These findings confirm that imitation is a reconstruction mechanism hierarchically organized.
