Abstract (EN): The estimation of internal forces and characteristics of human locomotion may lead to progresses in prevention or treatment of clinical cases, exercise and sport performance as well as in the project of training and rehabilitation equipment. Despite the efforts for the determination of ‘in vivo’ forces in synovial joints and at muscular level, there is no established methodology for direct measurement of internal forces during execution of normal human movement. Selected approach is based on inverse dynamic analysis, integrating data from ground reaction forces with kinematic displacements, anthropometric and electromyography data in order to achieve some insight into neuromuscular system revealed during human locomotion. Stretch-Shortening Cycle (SSC) is responsible for leg muscles forces that contribute together, with joint forces and moments, for the internal actions in association with external forces of gravity and ground reaction forces, for the biokinematic performance revealed in the present approach through vertical jump.
