This article supports the biomechanical analysis of the taekwondo kick, Dollyo Chagui. It was recorded by means of electromyography equipment, optoelectronic cameras, inertial sensor, and force platform, for data processing in BTS Bioengineering, Matlab and G-STUDIO software, in which the respective analysis of each shot is made. The characterization of the movements of 3 subjects with different experience in sport is presented, in order to show the differences in the movement technique. Subject 3 is a woman who is at a beginner level, her taekwondo practice began at the time of this research, subject 2 has an advanced level and has practiced taekwondo for the last 6 years, finally, subject 1 has a higher level with 9 years of experience in taekwondo and is dedicated to the modality of poomsae. Based on the records, the correct angles, muscle activation and positions that should be taken in each phase of the kick can be obtained, in order for the taekwondo athlete to improve in his execution and teaching. From the results obtained, the importance of a good technique to have a more efficient kick can be evidenced, as well as the importance of each of the 5 phases proposed
