The effect of harmonic exercises using the Rehacom system on mental alertness and developing motor response speed for handball goalkeepers aged (11-12) years

Abstract

The importance of the research lies in describing mental alertness exercises as a variable that affects the level of performance. Therefore, the researcher decided to use mental alertness exercises in handball, to be a ready tool to identify the level of focus and attention of goalkeepers. Hence, it will have a positive impact on the match. The research problem was that there was a weakness in the speed of the goalkeepers’ motor response during the process of defending their goal. They are exposed to a kind of loss of attention and lack of concentration. Which causes a weakness in their motor performance. Therefore, the possibility of using new methods and methods is the ideal solution for developing goalkeepers’ abilities and increasing their mental alertness. The research aims to identify mental alertness exercises through the use of the Rehacom cognitive system. The researcher assumes that there are significant differences between the pre- and post-tests for the variables under research and in favor of the post-tests. The research sample was handball goalkeepers aged between (11-12) years and the researcher used the Rehacom knowledge system and the statistical portfolio as tools for the research (SPSS) in processing the data, and the researcher concluded that the variable of mental alertness, and through the training program prepared in the Rehacom system, had a very clear impact on the improvement and development of the variable of mental alertness and response speed among goalkeepers.
