Summary/Abstract: Knowing best the Romanian kickboxing trainings level, but also having a good sense of the levels from other martial arts we considered that by using cinematic analyzes through modern technology applicable to motor activities we can objectify the executions of the technical elements from kickboxing in order to have a new approach in terms of evaluating them. For this study, a system of inertial measurement units was used, capturing the movement of the entire human body performing specific kickboxing techniques, each sensor being composed of 3D gyroscopes, accelerometers and 3D magnetometers, small in size along with advanced algorithms and biomechanical models..The system used in the studio was MVN Awinda, the version based on sensor straps, which transmits data to the PC / laptop wirelessly. There are 17 motion tracking sensors attached to the body in order to reconstruct 3D the human movement. Through this study we wished to link the methodical indications from the specialty literature and concrete technical executions, proving that the biomechanics elements can be objectively measured. Some of the most used striking techniques were chosen, performed by high level Romanian kickboxers and monitored with said equipment in order to objectify them and extract information useful for conducting trainings. We measured key kinematic parameters and extracted precise data about punching velocity, hips and shoulder rotations and angle varations.Likewise, the research is meant to be a step for future studies, even in other sports disciplines and to encourage the use of technology in sports training.
