PONCIANO, Katia et al. Effects of distribution of practice in the performance and retention of a motor task of synchronized swimming. Motri. [online]. 2018, vol.14, n.1, pp.212-216. ISSN 1646-107X.

The aim of the present study was to analyze the effects of distribution of practice (DP): massed practice (MP) versus distributed practice (DP) through performance analysis (scores) of 5 elements in addition to the final score of a technical routine (TR) of synchronized swimming (SS). 24 volunteers from both genres took part in the study and the groups were characterized as: MPG and DPG. Both groups received 10 sessions, 9 of them in the acquisition period and 1 for the retention test after 48 hours. Before the trials each volunteer watched a video with task to be performed and in each session, 4 TR attempts were performed with different rest breaks (RB) between them. In the retention test, both groups had the same RB for each trial. The results identified a positive effect of the test factor in element 3 between the pre and retention moments with a higher retention score (3.45 ± 0.96 vs 4.02 ± 0.62) and (3.86 ± 0.56 vs 4.17 ± 0.83) (p = 0.009). In elements 1, 2, 4 and 5 there was no effect of the test factor or interaction between the test and group factors. On the other hand, on the final score for the TR, there was an effect of the test factor identifying a trend between the pre and retention moments (3.73 ± 0.80 vs 4.10 ± 0.60) and (3.85 ± 0.58 vs 4.14 ± 0.74) (p = 0.013). It is concluded that the learning of a serial skill is possible independently of the used practice: MP or DP. An important variable that deserves discussion in future investigations in tasks of this nature is feedback.
