Resumo (PT): A análise biomecânica da marcha engloba, entre outros, dados cinemáticos, cinéticos e sinais electromiográficos, que, em conjunto, promovem a descrição do fenómeno da marcha. Neste trabalho é efectuada uma revisão dos estudos existentes que versam sobre os aspectos biomecânicos da marcha, de forma a perceber-se os componentes a ter em consideração na referida análise, bem como os modelos comuns que suportam achados experimentais. A análise efectuada permitiu verificar que a necessidade de redirecção da velocidade do centro de massa entre passos prediz um forte componente do dispêndio energético na marcha e que este, por sua vez, está associado à velocidade.
Abstract (EN): The biomechanical analysis of gait involves, among others, kinematic, kinetic and electromyographic signals, which, together, allow describing the gait phenomenon. This paper reviews studies focusing on the biomechanical aspects of gait, in order to understand which components must be considered in that analysis and the models supporting experimental findings. The analysis performed showed that the need to redirect the center of mass speed between steps predicts a strong component of energy expenditure in gait and that this is associated with speed.
