INFLUENCE OF AN INTERVENTION USING PRACTICES RANDOM AND BLOCKED IN THE PERFORMANCE OF OBJECT CONTROL SKILLS

ABSTRACT Based on the Contextual Interference Effect (EIC), we investigated the influence of a motor intervention in the performance of object control skills. Participated 60 children of six and seven years old, divided into three groups: random practice (GR), blocked practice (GB), control group (CG). The skills were tested with the Test of Gross Motor Development - 2 (TGMD-2). The experimental design included the periods: pre-test, practice sessions (12), post-test. GR and GB took part of the intervention. Descriptive analysis demonstrated that children showed adequate performance, according TGMD-2. In post-test, the Kruskal-Wallis test detected a significant difference between groups. The Mann-Whitney test was indicated that GR was superior to GB. The intragroup analysis, using Wilcoxon test, showed significant improvement in GR (p = 0.0004) and GB (p = 0.004). We conclude that the intervention improved the motor performance of object control skills, and GR showed the best performance in the post-test.
