Abstract

Introduction: The bandwidth knowledge of results can assist the performance of motor skills. Objective: Investigate the effect of bandwidth knowledge of results on performance consistency of motor skills. Method: Participated of the study 30 volunteers randomly assigned on groups bandwidth of 15%, which received knowledge of results when the error was beyond the stipulated bandwidth; and control, which received knowledge of results after every trial. The task consisted of pressing four keys on a computer alphanumeric keyboard in the sequence, 2, 8, 6 and 4 using the index finger of the right hand, with the target time of 900ms. The independent variable was manipulated on the 60 trials of the acquisition phase. The retention was performed 24 hours later, with 10 trials. Results: The performance of the bandwidth of 15% was more consistent during the acquisition phase and the retention test. Conclusion: The bandwidth has high probability to improve performance consistency of motor skills.
