: Perceptual performance plays an important role in acquisition of children's skills, and perceptual-motor speed exercises and balance are effective in future professional success. The aim of this research was to determine the effectiveness of perceptual-motor exercises with self-control feedback and coach control on balance and reaction time of children aged 6-8.

Methods: Using available sampling, 60 girls from 6 to 8 years of age were selected from Neishabur city and randomly divided into 3 groups: self-control, coach control, and control. In order to colecting data the static and dynamic balance plate, the dynamometer device and the eight-way reaction time recording device was used. To implement the exercises from the protocol of perceptual-motor exercises with self-control feedback (the children had access to their performance feedback based on their choice) and control tester (the tester gave them feedback on how to perform the movements) for 8 weeks, 3 sessions a week in 45-60 minutes and a total of 24 sessions were used. The data were analyzed using analysis of covariance test.

Results: The findings of the research showed that perceptual-motor exercises with self-control and examiner-control feedback have significantly improved the static (P=0.12) and dynamic (P=0.001) balance of children. Also, perceptual-motor exercises with self-control feedback and examiner control caused a significant improvement in reaction time (P=0.0001), and the effect of training (group) on reaction time was also significant (P=0.001), there was a further decrease.

Conclusion: These findings somehow support the effect of intervention exercises on children's perceptual-motor abilities, especially reaction time. ...
