The research proposes the analysis of some kinematic parameters of the launched velocity stride (the angles of the knee, hip and elbow joints), by comparing the flat and Kettler treadmill running, in order to model the technical training in trainings.The objectives of the research were the following: identification of the instruments and methodologies in order to model the kinematic parameters; establishing of the data acquisition ways; presenting the kinematic parameters of the launched velocity stride as a technical model; choosing the research athletes; determination of the kinematic parameters in launched velocity stride for every athlete both on the flat and treadmill running; analyzing by comparison of the determined kinematic parameters, both one to another, but also with the technique model. The kinematic analysis of movement in 2D system – Dartfish©, Analyzer module, emphasize the fact that the treadmill running is modifying the running specific kinematic parameters of the studied athletes, and that allows us to recommend not to be used for the learning, consolidation or perfection of the launched velocity stride.
