The purpose of this paper is to preparing proposed training vocabulary in critical speed training according to kinetic energy, and identifying the effect of critical speed training according to kinetic energy in developing some physical and physiological abilities and the achievement of advanced (5000) meter players. The researcher used the experimental design using the equivalent group method, as the experimental method. The researcher defined the research community as the players of Al-Kut clubs in the (5000) meter event, numbering (10) players, then the researcher conducted homogeneity for the research group in the study variables, which are (height, age, mass, training age, 60 meter run, 1000 meter run, 2414 test. One of the most important results reached by the researcher is that: The emergence of a positive development in the physical variables between the pre- and post-tests in favour of the experimental group, and the emergence of a positive effect size in the physical variables in favour of the experimental group according to the following sequence: (critical speed, running 60 meters, running 1000 meters). One of the most important recommendations recommended by the researchers is that emphasizing critical speed training using training specific parts of the race distance and at high intensity, and emphasizing the use of the high-intensity interval training method in long-distance events based on the critical speed test.
