The importance of the research lies in designing training for running curves according to centrifigural force law variables using body mass, radius and speed for 400m hurdlers.

The aim of the research was designing trainings according to centrifigural force law for some physical abilities in the second curve of 400m hurdles as well as identifying the effect of these trainings on some physical abilities in the second curve of 400m hurdles.

The researchers used the experimental method on (6) 400m hurdlers from the national center for gifted in athletics.

Achievement of 400m hurdles was measured as well as speed level during the second curve in first and second tests as well as 300m running test from high start.

The researchers concluded that these trainings according to centrifigural force laws have a significant effect on improving achievement in 400m hurdles.
