Resumo: Este estudo objetivou avaliar a eficiência mecânica do harai goshi aplicado em judocas de diferentes estaturas. Comparou-se: a variação angular de joelho, quadril e tronco do tori; o tempo para realizar cada fase da técnica; o deslocamento da trajetória vertical do centro de massa (ΔCM) do tori. Analisou-se cinemáticamente 10 aplicações do harai goshi pelo tori de estatura intermediária contra três uke (um de estatura menor, um equivalente e um maior a dele). Realizou-se aquisições de imagens a 180 Hz, utilizando-se o Sistema Peak Motus. Os dados foram analisados por meio da estatística descritiva, ANOVA e pos-hoc de Tukey (p ≤ 0,05). No deslocamento angular, houve maior eficiência do tori ao projetar o uke de maior estatura. O tempo para projetar uke mais alto foi menor. O ΔCM apresentou o mesmo padrão de projeção. Conclui-se que a técnica harai goshi é mais eficiente quando aplicada contra oponentes de estaturas equivalentes ou maiores.

Abstract: This study aimed to evaluate the mechanics efficiency of harai goshi applied in judocas of different heights. It was compared: the tori angular variation of knee, hip and trunk; the time to perform each technique phase; the displacement of the vertical trajectory of tori center of mass (ΔCM). Were analyzed 10 harai goshi kinematic throws, the tori with an intermediate height against three uke with lower, equivalent and higher height of him. The images were recorded at 180 Hz, using the Peak Motus System. The data were analyzed by means of descriptive statistics, ANOVA and pos-hoc of Tukey (p≤ 0,05). In the angular displacement, uke of higher stature had greater efficiency of tori when projecting. The time to project uke higher was lower. The ΔCM showed the same standard behaves. We conclude that the harai goshi technique is more efficient when applied against equivalent or higher opponents.
