The purpose of this study was to investigate if different practice schedules with different degrees of contextual interference (CI) influenced the participants' immediate and long-term putting performance and examine if performance changes were associated with concomitant changes in specific kinematic parameters. Twelve college students were randomly assigned to either a blocked or random practice schedule. On Day One each participant practiced putting to three targets (1 m, 2 m, and 4 m distance) for a total of 108 trials (36 trials to each target). On Day Two 30 trials of retention (10 trials to each target) and 10 transfer trials (3 m distance) were performed. To obtain a kinematic description of the putting action, an OPTOTRAKTM 3020 camera system recorded the 3D movement of the putter. Random practice participants exhibited poorer putting performance during acquisition compared to their blocked practice counterparts but showed superior performance in retention and transfer tests. While the blocked practice participants had significantly lower variability in the amplitude in the x-dimension for both backswing and downswing and impact velocity during practice, the random practice participants showed significantly lower variability in the amplitude of the x-dimension for the downswing and impact velocity during the retention and transfer phases.
