Numerous studies have examined the effects of focus of attention and quiet eye on motor performance, however the effects of these two variables in different load of task are ambiguous. Therefore, the purpose of the present study was to investigate the effect of the internal and external focus of attention instructions on quiet eye and accuracy of dart-throwing in two intensity of the secondary task. participants were 20 novice persons in dart-throwing that selected by convenience sampling; and in four dual-task conditions of internal attention-without tone estimation, external attention-without tone estimation, internal attention-with tone estimation, and external attention-with tone estimation performed dart throwing in counterbalance form that at the same time their gaze data recorded by binoculars eye tracking system. The result of accuracy showed that participants in external rather than internal attention condition and low- intensity rather than high-intensity condition had less radial error. The result of quiet eye showed that only the main effect of the secondary task was significant that participants in high-intensity of the secondary task rather low had more quiet eye duration. These results highlight the importance of external focus of attention in low and high secondary task load conditions for dart-throwing performance and direct the future research to explore more deeply the role of the quiet eye and attentional focus effects in dart-throwing performance.

The aim of this study was to investigate the effect of game-oriented exercises on motor development of overweight children with developmental coordination disorder. The research method was semi-experimental with pretest and posttest. 50 overweight children aged between 8 and 10 with developmental coordination disorder were selected and were randomly assigned to experimental (n=35) and control (n=15) groups after pretest. The experimental group participated in the protocol for 3 sessions per week during 3 months. MABC-2 test was used and SPSS 21 software was used for data analysis. The results of MANCOVA showed a difference between the experimental and control groups in at least one of the variables. Based on the results of one-way covariance analysis with a significance level of 0.05, there was a significant difference between the control and the intervention groups in motor development components and its subscales (hand speed, targeting and balance) and the experimental group got better scores. Therefore, it is recommended that the development of this disorder should be prevented in overweight individuals by designing different exercises and early intervention, and have a positive effect on their motor development.
