The purpose of this study was to investigate the effect of cognitive rehabilitation on Fundamental motor skills of children with DCD. The method of the present study was quasi-experimental, a pre- posttest design with experimental, and control groups. The statistical population of the study was 6 to 10 year old children in khonj city. For this purpose, 40 children with developmental coordination disorders were selected by cluster sampling method based on entry and exit criteria as members of the sample group and were randomly divided into experimental (n = 20) and control (n = 20) groups. Electrical stimulation was performed in 24 sessions and each session for 20 minutes with an intensity of one mA on the F3 and F4 regions on the study groups. The instruments used in this study included the DCD Questionnaire (DCDQ7), Movement Assessment Battery for Children - Second Edition (MABC-2), the Ulrich Test of Gross Motor Development (TGMD-2) and the Raven Intelligence Test. Data analysis was performed by Levin, Kolmogorov-Smirnov test and analysis of covariance at a significance level of 0.05. The results showed that Transcranial Direct Current Stimulation (tDCS) have a significant effect on increasing locomotor movement skills (F = 461.84, P = 0.001, Eta = 0.92), object control (F = 351.15, P = 0.001, Eta = 0.90,) and total motor skills (F = 597.21, P = 0.001, Eta = 0.94). This method can be useful and effective in improving Fundamental motor Skills, which is one of the major problems of these children.

Abstract
The aim of the current study was to determine the effect of two types of aerobic exercises on static and dynamic balance of the elderly women. 36 elderly women (60 to 75 years old) were randomly assigned to three groups: 1) walking or jogging (n=12) 2) exercise in water (n=12) 3) control (n=12).

The aim of the current study was to determine the effect of two types of aerobic exercises on static and dynamic balance of the elderly women. 36 elderly women (60 to 75 years old) were randomly assigned to three groups: 1) walking or jogging (n=12) 2) exercise in water (n=12) 3) control (n=12). Groups 1 and 2 participated in walking (jogging) and exercise in water program for 8 weeks, 3 session per week. The control group had their own daily activities and did not participate in any special kind of sports during this program. Sharpened Romberg and stick balance tests were used to measure the dynamic and static balance. Analysis covariance test (SPSS21) was used to check research hypotheses and to determine the difference among the groups. The results showed significant differences in posttest scores between experimental and control groups (P˂0.05). The results also showed that the group 1 (walking and jogging) gained more scores in dynamic and static balance than the group 2 (exercise in water). It seems that both types of the aerobic exercises especially walking and jogging are appropriate for decreasing the difficulties of this group and can be used as an exercise program in training centers.

The aim of this study was to investigate the effect of feed forward augmented information in model observation on learning mini basketball free throw skill in children. For this purpose, 45 children (10 years old) were selected as the sample by convenience sampling method and were divided into three groups: feed forward augmented information + observation, observation + KR feedback, and control (C). The research method was semi-experimental and research design was pretest-posttest and retention test. The task used in this study was mini basketball free throw skill. Firstly, the participants performed 15 trials in the pretest. The acquisition phase consisted of 6 blocks of 15 trials of observation followed by physical training. The retention test was performed 48 hours after the last training block in 15 trials. The data were analyzed by mixed analysis of variance, between-group analysis of variance and Tukey post hoc test. The results showed that both at the acquisition and retention phases, feed forward augmented information + observation group who were knowledgeable about the quality of the model prior to the observation showed better performance than the other two groups (P<0.05). Generally, these results showed that knowledge of the model performance before observation can make learning of a throwing task more significant than the time when they were knowledgeable after the observation. Therefore, it is suggested that feed forward augmented information on the quality of the model before observation should be used to improve the performance of the subjects.
