Abstract
The
purpose of present research was to answer to this question that how attentional
instructions and increasing frequency of movement impress on relative phase
stability in coordination bimanual movements? Participants (N=14) practiced in
phase and anti phase under internal and external attention and increasing
frequency. In acquisition phase apply external v. internal attention and after
each trial KP were given to subjects. On delayed retention test no render
specific instruction. The results revealed that no difference between internal
and external attention about affect on phase stability on in phase and anti
phase patterns. Also increase frequency of movement lead to higher variability
in anti phase and higher stability on in phase.

Abstract
This study aimed to investigate the effectiveness of basic taekwondo exercises on the executive functions of children with a learning disorder. For this purpose, 20 boys aged 10 to 12 years with learning disorder in Mashhad were selected and randomly assigned to training and control groups. The training group practiced Taekwondo for 12 sessions, each session lasting 50 minutes, repeating three days a week. The control group also engaged in their normal daily activities during this period. Changes in subjects' cognitive functions were measured before and after the training period by the N-back and the Tower of London tests. Analysis of variance with repeated measures was used for statistical analysis. The results showed that basic taekwondo exercises improve executive functions in the training group; All these changes were significant compared to the control group (p<0/05). Therefore, based on the results of the present study, it can be concluded that basic taekwondo exercises help to improve the executive functions of children with learning disorder by affecting brain areas related to executive functions.
