TERTULIANO, Ivan W.; UGRINOWITSCH, Alessandra A.C.; UGRINOWITSCH, Herbert  and  CORREA, Umberto C.. Effects of the extrínsic feedback frequency in serve of volleyball learning . Rev. Port. Cien. Desp. [online]. 2007, vol.7, n.3, pp.328-335. ISSN 1645-0523.

Twenty infants participated of this study aged from eight to eleven years. The task involved the volleyball under serve from the attack line in one side of the volleyball court aiming to reach one target positioned in the attack line of the opposite court, which could not be seen by the participants. There were two groups that deferred as a function of the frequency of augmented feedback: one information every two trials (G50%) or one information every three trials (G 33%). The experiment had 70 trials in the acquisition phase and 10 trials in the transfer phase. The second phase was carried out 5 minutes after the last of the acquisition, without augmented feedback. The results showed the best performance of the G33% in relation to G50% during the acquisition phase and transfer test as well. These results indicate that to smaller frequency of feedback is helpful to improve the performance of the volleyball under serve.
