Prof. Dr. Fahem Abdul Wahid Easa , Prof. Dr. Mohammed Jawad Kadhim, and Prof. Dr. Ghadah Muayad Shihab, professors from College of Physical Education and Sports Sciences, university of Baghdad, published a research paper in a global journal ( REVISTA IBEROAMERICANA DE PSICOLOGÍA DEL EJERCICIO Y EL DEPORTE),indexed in Scopus & Clarivate. The aim of the research entitled: (The Effect of Training Network Training in Two Ways, High Interval Training And Repetition to Develop Speed Endurance Adapt Heart Rate and Achieve 5000 Meters Youth) is to prepare training network in two ways of high interval and repetitive training to develop the endurance of speed and adapt the heart rate and achieve (5000 meters youth), where the research problem is determined that the achievement of the players of this activity does not rise to the acceptable levels, as a result of the weakness in the endurance of speed and adaptation of the heart rate and achievement, Accordingly, it became impossible to develop except through organized training, and the researchers used the experimental method with the pre- and post-test for the experimental and control groups for its suitability to the nature of the research. The research sample was conducted in a comprehensive inventory method, and the sample was divided into two groups, the experimental group and the control group, with (5 players) for each group, the training network were applied in the ways of high interval and repetitive training for eight weeks and by three educational units per week, the researchers used the statistical (spss). Conclusions: The training network in the two methods of high interval and repetitive training has a positive effect to develop endurance of speed and adapt heart rate and achieve 5000 meters youth.
