The purpose of this research was to investigate the effect of Purposeful challenging games on motor proficiency in children with developmental coordination disorder. The current research is semi-experimental with a pre-test-post-test design. The statistical population of the present study included children with developmental coordination disorder in Karaj with an age range of 8-9 years. For this purpose, a number of 45 people were selected by available and targeted sampling method and after obtaining written consent, they were randomly assigned to one of the two groups of challenging and non-challenging games. The tools used in this research were the Persian version of the DCD questionnaire, the MABC test and the TGMD-3 test. The implementation method was as follows: first, the TGMD-3 pre-test was taken from the subjects, then the research intervention was conducted in a challenging and non-challenging manner for a period of 10 weeks, 2 times a week and 45 minutes. After completing the intervention, the TGMD-3 post-test was taken from the subjects again. The data was analyzed using the statistical method of analysis of covariance. The results of this research showed that there was a significant difference between the impact of challenging games compared to non-challenging in motor proficiency; that this difference was in favor of the challenge group (sig=0.001). The results of this research support the viewpoint of the challenge point framework. Therefore, due to the greater effectiveness of challenge games,

One of the key factors for success in sport competitions is the ability to predict the movements of an opponent before performing them. The aim of the present study was to determine the effect of choking under pressure on predictive performance and to compare it between elite and novice fencers. In this quasi-experimental study, the subjects included 15 elite athletes of the youth fencing national team (16-20 years old) and 15 students from University of Tehran (18-22 years old) as novice athletes who were assigned to two groups by convenience sampling method. Prior to the test, 15 clips out of 100 video clips of different attacks on different parts of the fencers' body were performed and recorded by two professional members of the Iran National Fencing Team. After each video clip was stopped (before the sword hit the opponent's body), an answer sheet appeared on the screen and the subjects had to predict the location where the sword hit the opponent. The present study was conducted under high and normal pressure conditions. The high pressure condition was applied by the presence of a national team coach as the evaluator and in the non-pressure condition, the efforts were made without the presence of the evaluator. The results of mixed factor analysis of variance showed that the main effect of condition and group was significant but the interactive effect of condition and group was not significant. Bonferroni post hoc test results also showed that those players who were in normal condition had better predictive performance than those who were under the pressure condition; also, elite players had better predictive performance than novices in both conditions (P<0.05). But generally, choking under pressure decreases predictive performance in both elite and novice fencers.

Dyad training is a method in which pair groups participate in learning motor skills and it seems that it could be characterized as an optimal instructional environment through enhancing effectiveness and efficiency of training conditions. The aim of the present study was to examine the effect of dyad training on learning front crawl swimming. Twenty 7-10-year-old boys were assigned to two groups of dyad and individual training (each group 10 subjects). After receiving instructions and observing the perfect skill, subjects were paired; one half entered the water to perform the required skill and the other half stayed outside and like a coach gave his partner a feedback on his performance after observing his trial. After some trials, they exchanged their roles. However, after receiving instructions and observing the perfect model, all children in individual group entered the water and simultaneously performed the required skill. In the retention test, each child’s 10 m swimming was filmed and these clips were evaluated by 2 federation coaches using front crawl swimming checklist. The inter class correlation coefficient was 0.90. The results of retention test showed a significant difference between dyad and individual groups (P<0.05). So it can be concluded that dyad training method is not only economical in terms of energy consumption and instructional environment but also more effective compared with the traditional swimming instruction methods.
