Effect of volume of practice in children with probable Developmental Coordination Disorder
Abstract Children with Developmental Coordination Disorder (DCD) demonstrate a slower and more gradual ability to acquire and learn motor skills with practice. One question then is whether a higher volume of practice for these children could match the performance of children with typical development (TD). The present study aims to examine the effects of a higher volume of practice by children with probable DCD (pDCD) in relation to a lower volume of practice by children with TD. The MABC-2 was used to identify the participants' level of motor difficulty and set the composition of the groups. Two active video games (Nintendo Wii) were used for the practice. Each group was composed of eight participants, paired up by gender and age, TD (M = 111.87 months; SD = 4.05) and pDCD (M = 115.87 months; SD = 4.96). The TD group participated in seven practice sessions and the pDCD group participated in eleven sessions. Results regarding performance on Wii console games showed significant improvement from the first day of practice to the last day in both groups (pDCD and TD). A higher volume of practice for children with pDCD compared to their TD peers helped to increase the performance of the former group. Therefore, the pDCD group achieved a performance similar to the TD group in both practiced games.
期刊介绍:
The Brazilian Journal of Kinanthropometry and Human Performance is a journal of Physical Education, Kinesiology, Sport and related areas, whose focus is human movement, being reviewed by an international panel of peers, with emphasis on the measurement of the man in its morphological and functional aspects, as well as conditioning factors of physical performance. Given the multidisciplinary nature of the journal, these areas of study are approached in several contexts, with interactions with social, behavioral, health and environmental aspects. The journal publishes original articles as well as relevant Review/Update articles and Points of View.
