The objective this article is to verify the effects of an intervention program with exergames on the motor performance of children aged 8 to 10 years. The study included 64 children divided into experimental group and physical education group. The motor intervention used in this study was an exergame program with 18 sessions lasting 45 minutes each, twice a week. To evaluate motor performance before and after the intervention, the authors used the Test of Gross Motor Development -- Second Edition (TGMD-2). This study showed a positive effect on the motor performance of children ages 8 to 10 years. However, no significant differences were found in relation to the effect of exergames intervention in the experimental group when compared to the physical education group that participated in PE classes. The results of this study indicate that exergames are effective tools for the significant improvement of motor skills.
