“…Weerdesteyn et al (2008) taught martial arts-based lateral-fall techniques to naïve young adults during a 30-min training session and found that with this brief training session participants were able to reduce hip impact forces by as much as 17%. Gomes et al (2002) found that the retention and transfer of a novel Judo technique was optimized under practice conditions similar to those of competition after only eight days of 30 practice trials per day. Together, these results demonstrate the idea that a short training period can be effective for novel skill acquisition and short-term retention in martial arts.…”

Background. Experts of the Krav Maga (KM) self-defense system propose that KM techniques are based on simple body movements which are suggested to be learned rapidly and retained. This study investigated the acquisition, retention, and further improvement with additional training of two KM strike techniques among novice female practitioners: straight punch and defensive kick. Methods. Sixteen healthy females (age: 23 ± 3.7 years) without any previous martial arts/self-defense experience volunteered to participate. All participants received an initial 30-minute instruction session (AQ), taught by a certified KM instructor, where each technique was deconstructed into three checkpoints (defined as a component of the entire movement) for learning. Participants were divided into two groups, one of which received additional training. Several kinematic and kinetic measures were recorded at four timepoints: immediately before AQ, immediately after AQ, five days after AQ, and twelve days after AQ. Results. Results suggest that both techniques were learned rapidly, as checkpoint performance was significantly improved after AQ. Kick velocity and impact force also increased significantly after AQ, however, these measures did not change after AQ for the punch technique. Additional training did not improve either punch or kick performance beyond that learned during AQ. Conclusion. The findings from this study suggest that a single training session may be sufficient to learn and retain KM strike techniques relatively permanently; and the acquisition of the kick technique may lead to concomitant improvements in kick velocity and impact force.

“…Presume-se que foi a partir do início do presente século que as artes marciais passaram a ser mais focalizadas academicamente, como ocorreu na Aprendizagem Motora (por exemplo, CORRÊA; WALTER, 2016;GOMES et al, 2002;GOMES et al, 2017;GUTIÉRREZ-SANTIAGO et al, 2012;LAGE et al, 2013;SHIMODA et al, 2007). Nesta área de investigação, uma das linhas de pesquisa consiste em investigar as "tradições de ensino" No presente estudo, a arte marcial focalizada disse respeito ao aikido.…”

“…Alguns estudos questionaram essa forma de se ensinar os golpes comparando o processo de aprendizagem em um ambiente fechado (estático) e aberto (dinâmico, contextualizado -andando ou com movimentos específicos para preparar a execução do golpe) (GOMES et al, 2002, GOMES et al, 2005GOMES, 2007 No processo ensino-aprendizagem das técnicas de projeção de Judô, são realizadas repetições de movimentos específicos dos golpes denominadas de uchikomi. O uchikomi pode ocorrer com o oponente parado ou em movimento, com ou sem projeção do mesmo.…”

“…O uchikomi pode ocorrer com o oponente parado ou em movimento, com ou sem projeção do mesmo. No entanto, na tentativa de facilitar a aprendizagem, tradicionalmente a forma estática de execução dos movimentos é predominante no processo ensino-aprendizagem (ADAMS;CARTER, 1988;GOMES et al, 2002).…”

“…Segundo a hipótese de especificidade de prática na aquisição de habilidades motoras, aprender as habilidades em uma situação similar a real (contexto-alvo) é mais eficiente (WILLIAMS; DAVIDS; WILLIAMS, 1999). Assim, Gomes et al (2002) investigaram (KANO, 2008). Dois recursos podem ser basicamente utilizados ao se aplicar uma técnica de projeção durante a luta propriamente dita: o primeiro é posicionar o oponente em desequilíbrio para aplicar a técnica escolhida, empurrando-o ou puxando-o, de acordo com a direção em que se pretende projetá-lo; o segundo é aproveitar-se de um desequilíbrio ocasionado pela movimentação do oponente e aplicar a técnica mais adequada para a situação (VIRGILIO, 1986).…”

The judo contest has a dual feature, when the fighters try to throw each other, so that the environment is constantly changing. The Judo throwing techniques are consisted of three parts, the kuzushi (unbalance), the tsukuri (preparation) and kake (finishing), which must be performed in that sequence. The execution of each part influences the execution of the subsequent part. Thus, to let the opponent unbalanced (kuzushi) is essential for the successful implementation of the next parts. During the fight, to unbalance the opponent, it is common mutual displacements of push and pull movements, which can be called pre-kuzushi displacements. Considering that the kuzushi is crucial to the success of the throwing technique, and that pre-kuzushi displacements facilitate the effective occurrence of kuzushi, the aim of this study was to investigate the effect of the practice organization in learning pre-kuzushi displacements. Initially two experiments were carried out using the o soto gari technique: the first experiment with beginners and the second with participants not beginners (experience between three and six months of practice). Each experiment was composed by three groups: the constant practice group (Co), which performed the o soto gari technique with only one pre-kuzushi displacement; the blocked varied practice group (Bl), which practiced three possible pre-kuzushi displacements varying every ten trials; and random varied practice group (Al), which practiced three possible pre-kuzushi displacements at random. The experimental design consisted of three phases: Pre-test (3 tries), Acquisition (250 attempts) and Retention Test (3 tries, a week after the last day of Acquisition). The movement patterns were analyzed using recorded videos, considering the total configuration of the throwing technique, the prekuzushi displacements and the kuzushi concerning motor action and effect. In the Experiment 1 (beginners) Co showed superior results to the groups with practice variability (Bl and Al) in the pre-kuzushi displacements that was the aspect manipulated in the practice organization, and it was the only group to present progress in the effect of kuzushi. In the Experiment 2 (not beginners) the groups with practice variability (Al and Bl) were superior to Co in pre-kuzushi displacement; Al was superior to Co in relation to the motor action of kuzushi and only the variability of practice groups (AI and BI) showed improvement in the effect of kuzushi. Based on the results of Experiments 1 and 2 it was conducted a third experiment, adding a new experimental group to the three groups of Experiment 1-CoAl (constant-random group) that practiced 50% initial acquisition trials constantly and the remaining 50% randomly. The results showed superiority of CoAl compared to all other groups (Co, Al and Bl) in the retention test for total configuration of the throwing technique. It was concluded that the constant practice or previous experience before the variable practice is important in learning pre-kuzushi displacements that influ...
