The aim of this investigation was to study of effects of three different training schedules (blocked, serial and random) on performance and learning of basketball free throw from three different distances from the ring in experience subjects. 30 physical education male students that have been passed basketball course without experience in team training or competitions volunteered and divided into three groups randomly after performing pretest(fifteen free throws from 3 meters distance). All of them participated in 5 practice session in 5 continuously days(each session contain of 13 throws from 1.5 meters distance, 15 throws from 3 meters distance and 15 throws from 4.5 meters distance), and transfer test (15 throws from 3.5 meters distance and right side of ring side with 45 degrees angle). In acquisition stage, a 3(group)x5(session)ANOVA with repeated measurements on session factor revealed a significant main effect of session factor but the main effect of group and group x session interaction were not significant. The performance of 1 session was significantly lower than later sessions and the performance of the 5 session was significantly higher than other sessions. The result supported Magill and hall (1991) hypothesis that variability in parameter cannot show contextual interference effect.
