Abstract

Race ran 400 m hurdles is a special short races where energy systems overlap I and II
significantly and requiring the contestant cut portions of this race on my bow ran at least each
length (100 m) exposed during which the rider for the centrifugal force commensurate inverse with
speed, which is one of the obstacles facing such rapid and effective racers which adversely affect
both the length of steps running steps and barriers (crossed barriers) and average velocity and then
in the final completion And the importance of research in preparation under the law ran exercises
centrifugal and identify distress through within specific phases of the race associated with ARC ran
a jogging increasing speed (the first curve) and carry speed (second curve), research on a sample of
youth team players ran the 400 m hurdles, and video cameras were used to measure some variables


bio mechanical for passing the first barrier and the barrier, test ran 100 m hurdles at the first curve,
test ran 300 m hurdles (curves) And ran training drills dish strongly according to the law of
centrifugal, (8) week (3) training units per week, researchers concluded that the practice applied
badly centrifugal Act was active in the development of mechanical and physical capacities bio
mechanical variables private and complete running a sample search.
