Purpose

This study aims to determine the effect of the distribution of practice on learning the forehand shot in tennis.

Method

Twenty-four beginner tennis players participated in the study (13 males and 11 female; 8.63 ± 0.92 years old). The players were separated after groups -massed practice (N = 12) and distributed practice (N = 12). Each group practiced the forehand shot for 12 sessions, 4 series per session and 10 trials/series (6 weeks). The accuracy and efficacy were measured through one post-test and one retest, carried out 2 weeks after the last learning session.

Results

Significant improvements in accuracy between the pre-test and post-test (p=.004) and between pre-test and re-test (p=.006) were found in the massed practice group. Significant improvements in accuracy between the pre-test and post-test (p=.002) and between pre-test and re-test (p=.001) were found in the distributed practice group. No significant differences were found between groups but there was a favourable trend toward better learning in both, with improved accuracy and efficacy.

Conclusion

The motor learning through the distribution of practice among children has been noted, with a significant improvement in the skill acquisition of the forehand shot in the two groups. The results are useful because they clear up the doubts about how to plan the teaching of this stroke in tennis, confirming the suitability of carrying out learning programs based on massed and distributed practice.

网球正手击球的集体分散练习

目的

本研究旨在确定练习分布对学习网球正手击球的影响。

方法

24 名初学网球运动员参与了这项研究（13 名男性和 11 名女性；8.63 ± 0.92 岁）。选手在分组练习（N  =12）和分散练习（N  =12）后分开。每组练习正手击球 12 节，每节 4 个系列和 10 个试验/系列（6 周）。通过在最后一次学习课程后 2 周进行的一次后测和一次重新测试来衡量准确性和有效性。

结果

在集中练习组中发现前测和后测之间 ( p =.004) 以及前测和再测之间 ( p =.006) 的准确性显着提高。在分布式练习组中发现前测和后测之间 ( p =.002) 以及前测和再测之间 ( p =.001) 的准确性显着提高。两组之间没有发现显着差异，但两者都有更好的学习趋势，准确性和有效性都有所提高。

结论

已经注意到通过分配练习在儿童中进行运动学习，两组在正手击球的技能获得方面都有显着提高。这些结果是有用的，因为它们消除了关于如何规划网球这一击球教学的疑虑，证实了基于大规模和分布式练习开展学习计划的适用性。
