This research aims to design a proposed training program using the exercises and identify of the effects on: 1 - Some physical components of the members of the research sample. 2 - Some special abilities (physical, physiological) of the members of the research sample. 3- The level of digital achievement of 400 meters race for the members of the research sample.    The proposed training program will affect by using the Fartlek training positively on: 1 - Some physical components of the members of the research sample. 2 - Some special abilities (physical, physiological) of the members of the research sample. 3- The level of numerical achievement of 400 meters race for the members of the research sample.   Fartlek is one of the modern methods, which is the term Swedish Fartlek literally means playing at variable speeds, which is sprint for different distances length, short, medium and long speeds and variable aerodynamic and anaerobic to extreme intensity and the sprint distance to change in nature.(24)    The researchers used the experimental approach in designing the tribal and subdivision measurements for one experimental group in order to suit the nature of the research.    The sample of the research was chosen in a deliberate way from the total community of the research, which number (20) players in athletics in the second grade in the secondary school of sport in Zagazig for the academic year 2016/2017. A sample of 12 high - In addition to (5) other players for the exploratory experience of the same research community and excluded 3 players for injury and the following tables (1), (2), (3), (4) Physical - physiological) and digital level and physical components are under consideration
