Abstract EN

The research aims to:- preparing special exercises for the regressive abilities training method in the research variables (under study) for the 400 runners, and then identifying the effect of the regressive abilities training on the research variables (under study) for the 400 runners.

the research community was represented by runners aged between (20-22) years, representing the clubs of Sulaymaniyah governorate for the sports season (2019-2020) the number of members of the research community is (12) runners specialized in the two activities of running the 400 m freestyle, and they were distributed into two groups, the control and the experimental, and in a deliberate manner.).

the experimental group represented 6 runners effectively run 400 m freestyle, while the control group represented 6 runners in 400 m freestyle running activity, carrying out special exercises for rebounding ability differently from what the control group did.

then the researcher reached a set of conclusions related to the implementation of the working methods to verify the objective hypotheses.

including the regressive special exercises contributed to the development of the adequacy of some components of the blood, and as a result showed significant results in improving the digital level of the 400 m runners.

the use of a device to measure the pulse rate during rest, contributed to the legalization of the load and intensity of sports training, which was reflected in the adaptation of the internal organs, especially the cardiovascular system, because the pulse rate is an indicator of the level of the training status, as the pulse rate of the athlete during rest is directly proportional to the achievement (that is, the less the number of heart beats during rest decreased the completion time), which led to the development of the digital level for the two groups of runners (400 m).

in light of the conclusions reached by the researcher, he recommended a set of recommendations, including: directing the attention of coaches and athletes specialized in the effective (400 m) to periodically conducting laboratory tests for functional indicators and hormonal variables, to determine the health status.

interest in increasing hormonal studies, in particular cortisol; this is for its role in providing energy during high intensity physical exertion.
