Abstract
Biomechanics is the science that aims to study biological systems as well as understanding the behavior of the body during the performance of daily activities. The human march is the focus of countless works involving the understanding of its variables and the preservation of the systems that make up the human body. Human gait studies are carried out by means of kinematic data collections, whose objective is the study of motion, and kinetic data, in order to analyze the forces involved. This work focuses on the study of kinetic and kinematic variables. Volunteers, with no history of pathology related to human gait, were submitted to a controlled speed walk, and by means of two parallel positioned force platforms and a Qualisys image capture system, the reaction force of the Impact of the lower limbs on the ground and movement of the lower limbs during gait. The angles of the joints were found from a routine in Matlab through an equation involving routines to determine the Hip joint center and Cardan Angles. Strength data on the lower limbs were also analyzed in Matlab, distinguishing the force components at the foot pressure center in the three directions. The understanding of these variables may help in the diagnosis and treatment of human gait pathologies.
