چکیده:
This study attempted to investigate the effect of over-learning and off-line different periods on stabilization-based consolidation process and proactive Interference in explicit motor memory. Previous experiences can affect future performance. However, it is not clear how much exercise is needed to stimulate these effects, and what is the best offline period between workouts to prevent interference? In this research, the performance of 40 female students, who were between 20-30 years old and had been called to attend in the test voluntarily, was studied in two offline Periods of 5 minutes and 24 hours between the first (forehand) and the second (backhand) strokes. Data were analyzed using a variance analysis test with repeated measurement tests and a Tukey follow-up test. Two main findings emerged from the study. Firstly, it was determined that offline period (5 minutes and 24 hours) are not effective on the learning of the second task. The second finding was that overlearning performed consolidation in both of the offline Periods (24 hours and 5 minutes) and the learning of backhand stroke became resistant to anterograde interference. These results suggest that learning can play an important role in explicit motor memory, but offline period cannot make learning resistant to interference.

The Effect of Over-learning and Off-line Different Periods on Stabilization-based Consolidation Process and Proactive Interference in Explicit Motor Memory Somayeh Bakhshi Ph. D.
Department of Motor Behavior, Sport Science Research Institute of Iran, Tehran, Iran Abstract This study attempted to investigate the effect of over-learning and off-line different periods on stabilization-based consolidation process and proactive interference in explicit motor memory.
The second finding was that overlearning performed consolidation in both of the offline Periods (24 hours and 5 minutes) and the learning of backhand stroke became resistant to anterograde interference.
The present research, using two tasks of forehand and backhand strokes, probed on these two questions: "Is offline learning beneficial to the performance of learning the second task?" and "What is the effect of first and second task overlearning on anterograde interference and consolidation of the second task?" Method The present study adopted a pre-test/ post-test design.
Descriptive Statistics of Group Scores with Offline Periods of 5 Minutes and 24 Hours {مراجعه شود به فایل جدول الحاقی} Table 5 shows the difference in the mean scores task (forehand) and the second task (backhand) of the 4 groups.
By overlearning the second task (second phase), this harmful effect, which is the anterograde interference, disappeared; however, there was no significant difference between two groups of offline periods of 24 hours and 5 minutes.
In their study the beneficial effect of sleep was significant for consolidating motor activity; however, this fact is not consistent with our results because the current research shows that anterograde interference does not disappear even after 24 hours of offline periods.
