الملخص EN

The purpose of this study is to identify effect of feedback using an acrylic mirror on Technical performance level and some kinematic variables in 50 m freestyle stroke.

The researcher used the experimental method to design the two equal groups.

Our research included 24 subjects, who were divided into two groups: the experimental – (n=12) and the control – (n=12) groups.

The proposed program was implemented (2) units per week at (20) training units per day during the period of application, After the completion of the program was conducted after the measurements of the sample of the study Kinovea was used to extract the kinematic variables study, the technical performance of the research sample was assessed during the skill performance.

and data processing statistically and then present and discuss the results, the most important results were statistically significant differences between of the experimental group and the control on some kinematic variables in the freestyle stroke of the experimental group.
