This research aimed to develop some physical capabilities of the 800m running player, such as speed, endurance of speed, and endurance of muscles of legs, arms, body, and special physiological variables such as pulse, vital amplitude, blood pressure, maximum oxygen consumption, blood lactate level, and the digital achievement level of the 800m / sprint by designing a proposed training program using Varying training. The researcher used the experimental method and the research sample included (12) players from the Zagazig University Athletics team for the academic year 2018/2019. Some devices and tools have been used and the experimental group was subjected to the proposed training program for a period of (8) week, at the rate of three training units per week. The data extracted was processed with appropriate statistical treatments, including ("T" test to calculate the significance of differences and analysis of variance, as well as the formula for improvement ratios). Among the most important results: that the varied training led to improving the abilities of the 800m player who ran the special physical, such as speed and endurance of speed and endure the muscles of the legs, arms and body and special physiological variables such as pulse and vital capacity and blood pressure and the maximum oxygen consumption and the rate of blood lactate and the level of digital achievement of the 800m / r race for By designing a proposed training program using the differentiated training method. The researcher recommended the need to pay attention to developing the physical and physiological abilities of the 800-meter player, and that the differentiated training be an essential part of the sports preparation programs for the young and old and the importance of the differentiated training being linked to the nature of the sporting activity practiced.
