Technical actions performed by two groups of judokas who won medals at World Championships and Olympic Games during the period 1995-2001 were analyzed. In the Super Elite group (n = 17) were the best athletes in each weight category. The Elite group (n = 16) were medal winners who were not champions and did not win more than three medals. Super Elite judokas used a greater number of throwing techniques which resulted in scores, even when expressed relative to the total number of matches performed, and these techniques were applied in more directions than those of Elite judokas. Further, the number of different throwing techniques and the variability of directions in which techniques were applied were significantly correlated with number of wins and the number of points and ippon scored. Thus, a greater number of throwing techniques and use of directions for attack seem to be important in increasing unpredictability during judo matches.

RESUMONo processo de aquisição de habilidades motoras, importa tanto a estabilização funcional, como a capacidade de aplicação do que foi adquirido a novas situações, caracterizando um processo cíclico e dinâmico de instabilidade-estabilidade-instabilidade, que resulta em crescente complexidade. O presente estudo investigou a variável conhecimento de resultados (CR) no processo adaptativo em aprendizagem motora. De acordo com os resultados, regimes de CR menos freqüentes, menos precisos e com atividade no intervalo pós-CR (fatores de instabilidade, incerteza e desordem) não prejudicaram o processo adaptativo de aquisição de uma habilidade motora de controle de força manual.Palavras-chave: conhecimento de resultados (CR), controle de força, processo adaptativo, aquisição de habilidades motoras, aprendizagem motora. ABSTRACT Frequency, precision and temporal localization of knowledge of results and the adaptive process in the acquisition of a manual force control skill.In motor skill acquisition, not only functional stability is important, but also the capability of applying what was acquired to new contexts; this characterises a cyclic and dynamic process of instability-stability-instability, which results in increasing complexity. This study aimed to investigate the role of knowledge of results (KR) in motor learning viewed as an adaptive process. According to the results, KR regimes of low frequency and precision, and with interpolated activity on post-KR interval (factors of instability, uncertainty and disorder) were not prejudicial to adaptive process in acquiring a manual force control motor task.
