الملخص EN

The paper aims at: - Finding out the indication of differences of achievement between pre and post-tests of both experimental and control groups.

- Finding out the indication of differences of achievement of post-tests of both experimental and control groups.

- Finding out the indication of differences of the impact of training strategy by performance modeling that uses tempo trainer pro between both experimental and control groups in the post-tests.

The researchers uses the experimental method since it suits the paper concept.

The experiment was applied on a target of the Iraqi National Team advanced swimmers of 400 m freestyle swimming, (12) ones, so that the target is a collective one.

Those 12 were classified into two groups of ( 6) members each: experimental and control groups.

The similarity of (height, weight, training and time ages) variables was done, in addition to the equivalence of (performance modeling, both Anaerobic and aerobic abilities and achievement) variables between both groups.

Then, the experimental design was used by the researcher, which is entitled the equivalent groups of both pre and post-tests design, a matter that made the experimental group apply the experimental method of an independent variable (training strategy by performance modeling of critical swimming speed that uses tempo trainer pro) which is a training strategy the researcher put to achieve a good (400) m freestyle swimming, getting the way of dividing the regular distance, grouping the level of training capacity to get the best performance of the critical swimming speed to go with Anaerobic threshold speed of each swimmer, decreasing the lost time during that competition, and other training and strategic goals.

After that, the researcher interrelated with the Iraqi National Team method of (400) m freestyle swimming during competition periods so as the experimental group could be applicable for him on his paper achieving days: four days a week and it lasted for six weeks.

During that period, the experimental group had done (24) training units that applied the independent variable.

A number of scouting experiments were done before the application of the method on the paper target by the support of the assistant team, followed by a number of specialized tests on swimming from various and modern resources which had never been used and applied in our local and regional reality.

Therefore, they had been grouped into our local reality through the achieving of the scientific factors.

Furthermore, new statistical equations were used to achieve the tests: modeling and critical swimming speed ones.

Also, relevant and independent T tests were used to get the experimental outcomes.

An imported system (Tempo trainer pro) was also used to help achieving the paper aims together with pulse measuring watch (polar type).

The outcomes were furtherly discussed to help the researchers get the following concluding points : - There is a prominent effect of the use of performance modeling in the evolution of the level of tactical performance strategy for swimmers of the experimental group, which caused its superiority over the control group in the achievement variable of freestyle swimming (400) meters.

- There is a positive effect of using the water rhythm counter (Tempo Trainer pro) in adjusting the speed parameters according to the appropriate stresses for the training and racing distances until the regularity of the speed and good estimate of the appropriate distance time during the effort of the experimental group swimmers as it was a reason for their superiority over the control group in the dependent search variables.
