Agility is a fundamental component of taekwondo that improves the athlete's efficiency, safety and overall performance in training and competition. The objectives of this research refer to athletes who are regular members of the Drenova taekwondo club. The main goal is to examine the influence of SAQ training on the development of agility in taekwondo athletes. The first specific objective is based on the comparison of the difference in the results obtained in the agility T-test before and after the implementation of "Speed, Agility and Explosiveness Training", between athletes in a lower weight category (BM below 45 kg) and athletes in a higher weight category (BM above 45 kg). The second specific objective is similar to the first, but instead of the T-test agility score difference, the differences of the results obtained in the Test of Aerobic-Anaerobic Agility (TAAA) are compared. The research was carried out in the premises of the Drenova taekwondo club, with the initial measurements using the T-test of agility and TAAA, followed by the implementation of the SAQ training cycle, and the final measurement using the mentioned tests. 25 athletes of both sexes between the ages of 10 and 14 (cadets) actively engaged in taekwondo took part in the research. The research results point to the fact that the SAQ training program significantly increases the agility of athletes in taekwondo. On the other hand, it was shown that there is no significant difference in the T-test agility results difference between the group of athletes whose BM is below 45 kg, compared to the group whose BM is above 45 kg. The same conclusion applies to the comparison of the measurement of the difference in the difference in TAAA results between the mentioned groups. In addition to this research, contemporary available professional studies also indicate the usefulness of applying the SAQ training process with the aim of improving agility skills both in team sports and in taekwondo athletes.
