Background: Changes in the environment and living conditions are associated with changes in physical and cognitive functions. Objectives: The aim of this study was to examine the effects of a two-month military service period on soldiers' general health, social physique anxiety, and body mass index. Materials and Methods:The sample included all soldiers in Isfahan's army garrison training period. A 28-item questionnaire on general health, a social physique anxiety questionnaire (Hart et al. 1989) that measured the social physical anxiety and the ratio of weight to the height square calculating body mass index. Results:The results of the paired t-test showed that there were significant differences in pre-test and post-test scores on the general health aspects of anxiety and social physique anxiety and there were no significant differences in other aspects of soldiers' general health and body mass index. This suggests that the two-month training period affects only the variables of anxiety (anxiety, insomnia, and social physique anxiety). Conclusions:The findings showed that the military training period can significantly affect anxiety, but it cannot affect the health and body mass index.

Balance Coordination Brailletonik Training Mentally Retarded Background: The present research aims to consider the effects of training on the static and dynamic balance and coordination of the educable mentally retarded children. Method: In this semi-experimental study, 24 individuals were selected from amongst educable mentally retarded boy students with the calendar age of 6-9 years old who did not have any special illness and motion restriction. The participants were randomly divided into two identical control (n: 12) and experiment (n: 12) groups. The selected exercise program was performed for 8 weeks including three 60-minute sessions for each week. The subscales of the balance and coordination of the Lincoln-Oseretsky test were used to evaluate the participants' balance and coordination in the pretest and posttest. Results: The results showed that there was no significant difference between the two groups of control and experiment in pretest; whereas, a significant difference was observed in the static balance, dynamic balance and coordination between the pretest and posttest scores in the experiment group. The effect of Brailletonik training on balance and coordination was confirmed. Conclusion: According to the findings, it seems that Brailletonik training can be a suitable intervention to improve the motor elements in retarded children.

The purpose of this study was to examine the effects of different success criteria on motor learning in children. Forty-eight children threw soft-golf balls toward a circular target using their nondominant arm. On Day 1, they performed six blocks of 12 trials from 5.5 m. On Day 3, they performed a 12-trial retention test followed by a 12-trial transfer test. Participants were randomly assigned to one of four groups: difficult criteria for success, relatively easy criteria for success (RES), easy criteria for success, and control. Results demonstrated that there was a significant difference between the RES and control groups in their throwing accuracy on the retention and transfer tests, and the RES group had the highest score compared with the other two groups. This research suggests that providing relatively easy criteria facilitates motor skill acquisition in children.
