Scientific development in the field of sports has witnessed great boom in the field of using supporting means and instruments in developing achievements and acquisition of titles especially in track and field sports ..Therefore the scholar and the specialist of this field of sports have focused on the importance of different means and instruments in developing the physical capabilities and biomechanical variables particularly optimum angle in case of racers of long jump. The researchers have used new style by using pulling ropes pro and against movement in order to develop some physical capabilities and rising angle at sample of the research where they used pulling ropes towards and against movement of the rising board to develop capabilities of rising angle of sample of the research of long jump racers .. The researchers have used the new style of rope pulling to develop physical capabilities of the sample of the research and optimum angle at the racers of the sample .The problem of the research was solved by using this effective in method in speed of hitting the board and the strength of hitting the board at the sample of the research…Accordingly , the researchers have used this method in exercises to develop physical capabilities of the sample of the research and optimum angle at the racers .
