local.description.resumoBackground & Study Aim: The literature on motor learning characterizes feedback as a critical component of learning, making it an important factor in the process of motor skills acquisition. The aim of the present study was to verify the effects of the bandwidth in the acquisition of a judo motor skill. Material & Methods: Thirty-six volunteers were randomly assigned to three experimental groups: control group (CG) that received knowledge of performance (KP) in all trials; that received (KP) in a wide bandwidth (WBG); that received KP in a narrow bandwidth (NBG). The task used in this experiment was the o soto gari throw. The experiment consisted of an entrance test, acquisition phase, post-test and retention test. Results: The athletes from CG presented worse results when compared to the other bandwidths groups. Also, the wide bandwidth helped in the changes of performance and pattern of the movement, favouring the improvement of the consistency and precision. The wide bandwidth of KP aided in learning complex motor skills, and that the narrow bandwidth, despite helping to change the pattern of execution, was not enough to result in changes in performance. The wide bandwidth of KP was more adequate for sports learning. Conclusion: Taken together these findings showed that the combination of a lower frequency of KP supply, the effect of qualitative information on performance, coupled with an optimal intertrial interval, was the key to the effects of the bandwidth of KP on the acquisition of a complex task with specific demands like the judo throw: o soto gari.
