Abstract EN

The research aims to: 1-Identify the effect of the educational program using some corrective exercises in technical performance and some Biomechanics variables and achievement freestyle swimming.

2-Identify the technical performance of the freestyle swimming and some Biomechanics variables and achievement for the two experimental and control group.

3- Comparison pre and posttest of the technical performance and the values of some variables and achievement of Biomechanics in freestyle –swimming between the experimental and control group.

4-Comparison in the values of posttest between (experimental and control group) in technical performance and some Biomechanics variables and achievement in freestyle swimming.

The researchers used the experimental method (the analytical comparative) for suitability and the nature of the research.

The community was from of the third school year students in the college of Physical Education at the University of Salah al-Din Erbil for the academic year (2014-2015) totaling 92 students representing the people of group (C, B, A), the reason for choosing students this stage is that the material swim taught at this stage, the research sample was selected group(A) by lot totaling 32 students, was selected students who know the basic skill initial of freestyle swimming intentional totaling (20) students were distributed to two equal groups and randomly, and a control group experimental group and the rate of (10) students per group, and through the application of the curriculum and tests absent two student from each group and became the number of the sample in each group (8) students only, the sample represent for )% 937.12( from the original of the research community.

Done prepare curriculum using exercise corrective for (10) weeks of (1) educational units per week on Thursday and reached the educational unit per time (90 minutes) includes some exercises corrective the biomechanics for stages of freestyle swimming and done scientific observation and indirectly, to evaluate the performance technical in the freestyle swimming depending on the form of evaluation codified for the freestyle swimming by three arbitrators specialists in the field of swimming to the pre and posttest to the sample research .It used of statistical bag (SPSS) in processing and finding out the data belong to the research as it used the arithmetic mean, standard deviation and test (t) for samples dependent and independent.

The researchers concluded the following: 1- Attain corrective exercises significant effect in some of the biomechanics variables, including time of (25m) freestyle swimming and the number and distance and the speed of the arms rotation.

2 -Attain a variable time of rotation and frequency of arms develop appear through differences of the mean but did not reach to the significant level.

3-The corrective exercises affected significantly in the technical performance of the freestyle swimming directly.
