ABSTRACT
This study analyse the influence of Knowledge of Results (KR) with different accuracy levels on the learning rate of a throwing skill of spatial non-vision accuracy, during the acquisition stage. We assessed the number of successful events, the distance from the target and the consistency of the responses obtained by 180 subjects. We applied three accuracy levels: KR1 – subjects were informed about reaching the target or not; KR2 – informed about the direction of the failure events; and KR3 – informed about the direction and quantification of the failure events. All groups improved their rate of success –15.56% in KR1, 14.45% in KR3 (p
