The Effects of Secondary Motor Task and Blocked Versus Random Practice on the Acquisition and Retention of Target Shooting Skill With Recreational Rifle and a Test of Cognitive Elaboration Hypothesis

The purpose of this investigation was to determine the effects of a secondary motor task during the acquisition of blocked versus random practice schedule of rifle shooting from the distances of 8,11,14 meters and the combination of these distances on 132 male students for 6 consecutive days. In this fully crossed factorial design (5 rifle shooting dart throwing), data were analyzed using SPSS:PC version 14. The results of analysis showed that dart throwing had no significant effect on the acquisition trial (P<0.05), but it had a significant effect on the retention trials (P = 0.001). These findings were interpreted as the validity of the elaborative hypothesis considered in the literature.
