The analysis of sports technique between different performance levels serves to establish methodological comparisons that contribute to the improvement of specialized motor performance, including eminently technical-tactical sports. In this sense, the objective of the research is to analyze the biomechanical differences between professional and amateur taekwondo athletes in the performance of the Chigo-Chagüi kick with front leg. Two independent groups were studied, 15 Beginner Athletes (DPRI in Spanish) and15 Professional or advanced Athletes (DPRO in Spanish); indicators of Speed, Flexion Angle and Center of Gravity were studied and a comparison was established. An initial angle of DPRO=28.4° and DPRI: 27.34° (p=0.309) and an impact angle of DPRI= 117.93º and DPRO=129.2º (p=0.001) and a final angle of DPRI=31.34º and DPRO=26.34º (p=0.057) were determined, with a kick execution time of DPRO=1312ms and DPRI=1462 ms (p=0.009), a maximum velocity of DPRO=6.86 m/s and DPRI=5.47 m/s (p=0.003) and an average acceleration of DPRO=48.35 m/s2 and DPRI=36.55 m/s2 (p=0.029), being the center of gravity for the impact point in Axis X with no significant differences (p=0.506) and in Axis Y with significant differences between independent groups (p=0.029). The differences between advanced and beginner athletes in the chigo-chagüi kick with front leg are usually remarkable in most of the indicators analyzed, being the level of the athlete an indicator that allows describing the technical deficiencies.
