The objective of this study was to compare the effect of digital (i.e., augmented reality [AR]) and live demonstrations of two fundamental motor skills. The motor skills were horizontal jump and over-the-shoulder throw with performance criteria described in the Test of Gross Motor Development—Second Edition (TGMD-2). We developed a digital model using AR installed on a tablet computer compatible with the Android operating system. We recruited 131 children and assigned them to three age groups: G1, 3-5 years old ( M = 4.25, SD = 0.71 years); G2, 6-8 years old ( M = 7.16, SD = 0.79 years); and G3, 9-11 years old ( M = 10.13, SD= 0.84 years). Randomly, half of the children in each group performed the two motor skills after watching either the AR or the live demonstrations; seven days later, all children repeated the motor skills with the demonstration type inverted. We applied Wilcoxon’s test with statistical significance set at p < .05 and found no significant performance differences based on demonstration exposure from AR versus live modeling. We propose that AR technology is a potential tool for demonstrating human movement.
Purpose. the paper aimed to compare the performance related to passing among the categories of professional and U-15 futsal players, in open and closed contexts. Methods. In total, 25 athletes were evaluated in 2 tests, namely open and closed contexts. the former aimed to observe the complexity of in-game execution in a dynamic and unpredictable mode, while the closed test simulated a closed and predictable task through the isolated execution of the pass. to compare the groups, the Student's t and Mann-Whitney tests were used, respectively, with the level of significance at p < 0.05. Results. there were significant differences across categories in the performance related to the open pass skill (p < 0.001). there were no significant differences in the closed pass context (p = 0.414). Conclusions. Only the open context test identified differences in performance between categories, with the superiority of professional players.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
