The purpose of this study was to analyze the relationship between running speed and ground reaction force.Subjects were 5 male top level collegiate sprinters(best record 100m : 10"72 200m : 21"46).Analyzed paramenters were running speed(1st, 3rd, 5th, 20m, 50m)and ground reaction forces.The results obtained were as follow;1)The data of running velocity was determimed top level sprinter in inter college. 2)Acceleration forse of 1st step was bigger than others.1st step was twice as big as 3rd.step Acceleation impulse was getting equal braking impulse with runnning distance. 3)It was determined that 50m run phase was running to fixed at maximum velocity.Bue, it phase didn't Fixed for acceleration-decelertion force rather than more accelelation phase.It was concluded that rotational force was solved between ground surface and kicking to the shose surface.It was need of clear that rotational force.
