Special Training According to Centrifigural Force Law on Some Physical Abilities In The second Curve and Achieving 400 m Hurdlers

Abstract

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 training according to centrifigural force law for some physical abilities in the second curve of 400m hurdles as well as identifying the effect of these training 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 the high start. The researchers concluded that these training according to centrifigural force laws have a significant effect on improving achievement in 400m hurdles.
