الملخص EN

The study aimed to identify the impact of the training exercises of the turn in some Biomechanics the values of variables and achievement in the 100m /80freestyle swimming in pool length of 25m, correlation between some Biomechanics variables for turn and achievement in swimming 100 meters freestyle.

The researchers suppose that there is significant differences between the pre-test and post in some Biomechanics variables and all achievement among the four distances in the pool, 25-meter pool for the 100-meter freestyle swimming.

There were significant correlation between some Biomechanics the values of variables and achievement in the 100 meters freestyle swimming pool length of 25 meters.

They use the experimental method to suitability and analytical research problem.

The research sample consisted of (5) swimmers representing Erbil team in freestyle .Camera sophisticated imaging machine Chinesemade speed (241 r / s) were placed within 14 meters of the left side of the swimmer up his camera lens 50 cm.

After the pre-test they put training exercises for the turn according to the load training and after completion was conducted post-test studied biomechanics variables (time distance of every 25 Metro 100 m and variables along -time -speed - frequency arms cycle) and were processed statistically using the Statistical bag SPSS to extract Biomechanics variables .

The results were Training exercises affected the number of biokenmatics variables, including the 25-meter main distance first, third and fourth in the interests of post test .Training exercises effected on the main number and distance and time variables of time and were in favor of posttest for all distances of 25 meters four .The training exercises for rotation of the great influence and clearly in the test posttest on the most important variables, namely the total time and the number of circle of the arms to swim the 100m freestyle swimming and for the benefit of the post test
