Comparison the Effect of High and Low Contextual Interference Training on Performance Accuracy

Objective: The aim of this study was to determine the differences between different methods of contextual interference (High and Low) on accuracy.
 Methods: The subjects were 51 people from Shiraz Mental Health Park Rehabilitation Center who were purposefully selected and after the pre-test, they were randomly divided into three groups. The High and Low interference groups performed 180 Frisbee attempts (backhand, forehand, and hammer) and the control group played a team game at the same time as the intervention groups. Then, acquisition, retention and immediate transfer tests were taken. Accuracy was measured using a researcher-made test.
 Results: The results of repeated measures test showed no significant difference in the phase of acquisition and there was a significant difference between the groups in the phases of transfer (P = 0.011) and retention (P = 0.026).
 Conclusion: It seems that the results of this study can be effective in reducing researchers' concerns in simultaneous training of several motor skills by emphasizing the movement pattern and achieving the goal of movement (accuracy). Findings indicate that the use of contextual interference methods, at high levels, leads to time savings and stabilizes the pattern of movement in the learning phases.
