The research included a study of some physiological and bio-kinetic variables and the achievement of the 400m hurdles under 20 years old. Research problem included studying the disparity between the best local achievement when compared with the best Arab achievement and the best Asian achievement, which prompted the researcher to prepare a training program and apply it to two research groups. The first group included isolated interval training, and the second group included isolated interval training with a beta-alanine supplement. One of the most important objectives of the research is to prepare isolated interval training sessions and include them in training units, and to identify the effect of these exercises, in addition to the beta-alanine supplement, on some physiological and biomechanical variables and performance of 400m hurdlers under 20 years old. As for the most important research hypotheses, there was a positive effect of isolated interval training and the beta-alanine supplement on some physiological and biomechanical variables and performance of 400m hurdlers. There were statistically significant differences between the post-tests in favor of the second experimental group. The researcher used the experimental method by designing two experimental groups. The first
experimental group included only the training program (isolated intervals), while the second experimental group included the training program with the supplement (isolated intervals and beta-alanine supplement), with pre- and post-test measurements and tests to achieve the objectives and hypotheses of the research. The research community was determined by runners from clubs in the holy city of Karbala under 20 years old in the activity. (400m hurdles) with a total of (10 runners) from (7 clubs). The researcher selected his research sample using a comprehensive inventory method, consisting of (10 runners), which represented (100%) of the research community. They were divided randomly by drawing lots into two groups: the first experimental group and the second experimental group, with (5 runners) for each group. Researcher used statistical package (SPSS) to process the test results. Among the most important conclusions reached by the researcher is that the isolated interval training and the beta-alanine supplement prepared by the researcher resulted in an improvement in physiological and bio-kinematic variables and the achievement of the 400m hurdles for under-20s. This was confirmed by the results obtained. The beta-alanine supplement used in the second experimental group contributed to a greater improvement in the second group than the first experimental group in the aforementioned variables. Among the researcher’s recommendations is the necessity of using isolated interval training in high-intensity events and using and benefiting from these exercises and applying them to other age groups. He also recommends the use of Beta alanine supplement for runners is beneficial in helping runners complete their training to the fullest and with the required intensity, and to improve performance. It is necessary to conduct a study similar to this study on other categories or variables, and on other age groups and gender.
