Previous issue date: 2015-08-04 / Introduction : Physical activity and martial arts have a major influence on cognitive performance of elderly, and can be important tools for preventing the development of cognitive decline and improve intervention strategies. Martial arts, especially Karate-Do, our object of study, are considered forms of complete exercise, which besides bringing benefits to physical health, contribute to stimulate motor and cognitive skills, improved quality of life and emotional aspects of their practitioners. Objective : to determine the effectiveness of a Karate-Do training, Wado-ryu style, on cognition in healthy elderly. Methods : A randomized controlled clinical trial was conducted with 33 elderly divided into two groups: Karate group (n = 16) and Control group (n = 17). In the pre and post-intervention phases, the elderly answered a sociodemographic questionnaire, a battery of neuropsychological tests (evaluation of attention, memory, language, perception, visoconstruction abilities and executive functions), subjective cognitive complaints and mood scales (anxiety and depression). Intervention with Karate-Do was conducted twice a week, lasting 60 minutes each session, for 12 weeks. The exercises consisted of kihon, kata and kumite typical of Karate-Do. Control group did not perform any physical activity or cognitive stimulation during the intervention period. Data analysis was conducted using descriptive and inferences statistics. A comparison of performance neuropsychological tests and subjective complaints scales, within and between-groups in the pre- and post-intervention, was performed using the Mann-Whitney test and Wilcoxon test. Results : the groups showed no statistically significant differences in the sociodemographic and clinical data in the pre-intervention phase. In intra-group comparison, at the end of the intervention, Karate Group achieved better performance in visual memory (Mpre: 11,78; sdpre: 6,12 / Mpost: 14,38; sdpost: 5,35 / p: 0,041), alternating attention (Mpre: 146,98; sdpre: 92,74 / Mpost: 121,39; sdpost: 70,71; p: 0,017), episodic verbal memory (Mpre: 43,88; sdpre: 7,74 / Mpost: 49,06; sdpost: 8,06; p: ?0,001), executive functions tasks (Mpre: 21,88; sdpre: 15,07 / Mpost: 31,88; sdpost: 14,91; p: 0,024) and reduction of subjective memory complaints by relatives (Mpre: 24,63; sdpre: 3,12 / Mpost: 19,69; sdpost: 5,61; p: 0,003). Control Group showed no significant differences in cognitive performance between pre- and post-intervention. In between-groups analysis at post-intervention phase, Karate group had higher scores than the Control Group in visual memory task (MGK: 14,38; sdGK: 5,35 / MGC: 10,03; sdGC: 3,43; p: 0,019) and reduction of subjective memory complaints by relatives (MGK: 19,69; sdGK: 5,61 / MGC: 24,41; sdGC: 5,12; p: 0,008). Conclusions : The Karate-Do training, Wado-ryu style, was effective in cognitive stimulation in healthy elderly, especially in tasks of attention, memory and executive functions. / Introdu??o : a atividade f?sica e artes marciais possuem uma grande influ?ncia no desempenho cognitivo de idosos, e podem ser ferramentas importantes de preven??o do desenvolvimento de decl?nio cognitivo e incrementar estrat?gias de interven??o. As artes marciais, especialmente o Karate-Do, nosso objeto de estudo, s?o consideradas formas de exerc?cio completas, que al?m de trazerem benef?cios ? sa?de f?sica, contribuem para estimular habilidades motoras e cognitivas, melhora da qualidade de vida e de aspectos emocionais de seus praticantes. Objetivo : verificar a efic?cia de um treinamento de Karate-Do, estilo Wado-ryu, sobre a cogni??o de idosos saud?veis. M?todo : realizou-se um ensaio cl?nico controlado e randomizado com 33 idosos divididos em dois grupos: Grupo Karate (n = 16) e Grupo Controle (n = 17). Nas etapas pr? e p?s-interven??o os idosos responderam a um question?rio sociodemogr?fico, a uma bateria de testes neuropsicol?gicos (avalia??o de aten??o, mem?ria, linguagem, percep??o, habilidades visuoconstrutivas e fun??es executivas) e a escalas de queixas cognitivas subjetivas e de humor (ansiedade e depress?o). A interven??o foi conduzida duas vezes por semana, com dura??o de 60 minutos/aula, por 12 semanas. Os exerc?cios eram compostos de kihon, kata e kumite t?picos de Karate-Do. O Grupo Controle n?o realizou nenhuma atividade f?sica ou de estimula??o cognitiva durante o per?odo de interven??o. A an?lise dos dados foi realizada com estat?sticas descritivas e de infer?ncias. A compara??o de desempenho nos testes neuropsicol?gicos e nas escalas de queixas subjetivas intra e entre-grupos, nos per?odos pr? e p?s-interven??o, foi realizada atrav?s do Teste U de Mann-Whitney e Wilcoxon. Resultados : os grupos n?o apresentaram diferen?as estatisticamente significativas com rela??o aos dados sociodemogr?ficos e cl?nicos na etapa pr?-interven??o. Na compara??o intra-grupos, ap?s a interven??o, o Grupo Karate demonstrou diferen?a significativa nas tarefas de mem?ria visual (Mpr?: 11,78; dppr?: 6,12 / Mp?s: 14,38; dpp?s: 5,35 / p: 0,041), aten??o alternada (Mpr?: 146,98; dppr?: 92,74 / Mp?s: 121,39; dpp?s: 70,71; p: 0,017), mem?ria verbal epis?dica (Mpr?: 43,88; dppr?: 7,74 / Mp?s: 49,06; dpp?s: 8,06; p: ?0,001), fun??es executivas (Mpr?: 21,88; dppr?: 15,07 / Mp?s: 31,88; dpp?s: 14,91; p: 0,024) e queixas de mem?ria pelo familiar (Mpr?: 24,63; dppr?: 3,12 / Mp?s: 19,69; dpp?s: 5,61; p: 0,003). N?o foram encontradas diferen?as significativas de desempenho cognitivo do Grupo Controle entre os per?odos pr? e p?s-interven??o. Na compara??o entre-grupos no ap?s a interven??o, o Grupo Karate apresentou escores mais elevados nas tarefas de mem?ria visual (MGK: 14,38; dpGK: 5,35 / MGC: 10,03; dpGC: 3,43; p: 0,019) e redu??o nas queixas subjetivas de mem?ria pelo familiar em compara??o ao Grupo Controle (MGK: 19,69; dpGK: 5,61 / MGC: 24,41; dpGC: 5,12; p: 0,008). Conclus?o : O treinamento de Karate-Do estilo Wado-ryu mostrou-se eficaz na estimula??o cognitiva de idosos saud?veis, especialmente em tarefas de aten??o, mem?ria e fun??es executivas.
