Abstract EN

The research aims to determine the effect of using some exercises that were similar to the free-style swimming movements (Isokenatic) in order to develop the explosive power by using the high-intensity periodical training and repetitive training methods for 50 m free-styleswimming.The researcher used the experimental method and made two equal groups for the pre-test and the post-test in this study.

The study was conducted intentionally on a sample of college students from the Faculty of Physical Education / Baghdad University, who were practicing the sport of swimming regularly for the first level in the academic year (2013-2014).

The research sample was of (12 students), who were divided into two groups and by (6) students in each group.

The first experimental group used the exercises that weresimilar to the free-styleswimming movementswith the high-intensity periodical training method while the second experimental groups used exercises that weresimilar to the free-styleswimming movements with the repetitive training method.The results of this study were that, there were no significant differences between the two measurements, the pretest and the post-test, for the two experimental groups, which used the high-intensity periodical training and repetitive training methods for 50 m freestyle swimming and for the favor of the post measurement.

It was also found out that there were no statistically significant differences in the explosive power and the achievement of 50 m free-style swimming and for the favor of the group that used the high-intensity periodical training.
