摘要：In this study, we examined the last four strides of athlete's who had two different long jump performances. Twenty male long jumpers’ long jump performances were recorded two video cameras (50Hz). Differences the lengths of last four strides, velocity of center of gravity (CG) which was formed during the last four strides in two groups were investigated. It was determine significant differences the lengths of last four strides; the height of the athlete's CG during the last four step (except the last step); the fourth to last stride velocity between two Group I and Group II (p<.05). There were significant differences horizontal and vertical velocity at the instant of touchdown and horizontal velocity after the touchdown between in two Groups (p<.05).
