Introduction: When a person practice some skills which are related to each other, contextual interference occur. This study investigated the experiences and contextual interference effect on learning three selected skills in handball.
Methodology: The subjects of this study consisted of 200 female students aged 11 to 13 years. 80 female students were randomly selected for this purpose. All participants completed the personal information form and then examined in pre-test included chest pass, overhead pass, three step shot. Each person performed each skills 5 times. Then people were placed in fourth group of 20 (novel/block; novel/random, semi-skilled/block, semi-skilled/random). After correct training way of implementation, the participants were requested to practice each skill 20 times with blocked and randomized groups and participated in retention test of the next day and performed each skill 5 times.
Results: To check the normality of the data, Kolmogorov-Smirnov was used. Hence the data normality did not observe a non-parametric test used for data processing. U-Mann-Whitney test results revealed that blocked training programs in beginners did not clear the effect of contextual and there was no significant effect between groups with blocked and randomized exercises. Also blocked and randomized training programs of handball skills had not marked interference effect in semi-skilled persons except overhead passing skill and no significant effect were seen between groups with blocked and randomized exercises except overhead passing skill. Group with blocked practice were better than random practice group in next to ears passing skill.
Discussion: It seems that the number and type of task training affected the results. These results can be confirmed by the fact that even semi-skilled people to work in difficult field conditions require a greater effort to learn skills, an explanation for the reason that why changing skill or motor program increase learning base on learner's ability and is related to the reason of information processing. Based on Miller and Newell information segmentation mode, person's ability to process information is limited and level of information which a person is able to process cannot be increase but efficiency of information processing can be improve
