Abstract

UGRINOWITSCH, Herbert et al. Effects of the bandwidth KP on the learning of the volleyball tennis serve. Motriz: rev. educ. fis. (Online) [online]. 2011, vol.17, n.1, pp. 82-92. ISSN 1980-6574.  http://dx.doi.org/10.5016/1980-6574.2011v17n1p82.

This study aimed to investigate two bandwidth Knowledge of Performance (KP) effects on the learning of the volleyball tennis serve. This question was tested with a thin and wide bandwidth KP plus a control group. The study was composed by a pre test, acquisition phase and retention test. It was analyzed performance and components of the motor pattern measures. Although the groups showed similar performance on retention test, only wide bandwidth conducted to a better performance. Although all groups showed similar performance during retention test only the wide bandwidth conducted to performance improvement. Moreover, the wide bandwidth conducted to more changes in movement pattern than thin bandwidth or control group.

Keywords : Knowledge of performance; Bandwidth feedback; Motor learning.
