Abstract
Aim: Several factors are considered crucial in the formation of motor memory and learning, including the amount of practice and the role of sleep in memory consolidation. However, it is unclear whether the quantity and quality of sleep before and after training and double training can affect performance. Accordingly, the present study aims to investigate the effects of intensified training on forehand serve accuracy in table tennis learning, with an emphasis on the mediating role of sleep quality and quantity before and after training.
Methods: The statistical population consisted of 200 students aged 13 to 15 years, from which 60 volunteers were randomly assigned to one of two groups: regular or double practice. In the first session, the regular and intensified groups performed 100 and 200 trials, respectively, followed by 30 trials each in a second session two days later. Accuracy and retention indices were calculated based on forehand serve scores. Sleep parameters were measured using a Xiaomi wristband twice: two days before and after training sessions.
Results: One-way ANCOVA results showed that the intensified training group had a higher learning index than that of the regular training group (p=0.017). No significant differences were observed in retention and relearning indices (p≥0.05). Additionally, no significant correlations were found between sleep parameters and learning, retention, or relearning indices (p≥0.05).
Conclusion: It is concluded that double practice resulted in improved performance on the training day, while sleep before and after the training did not have a significant impact on performance improvement.
