Abstract:
Background: Plyometric training involve an eccentric-concentric contraction cycle, in which, concentric contraction is performed immediately after eccentric contraction. Plyometric training improved and increase agility and explosive power. In this type of training, muscles exert their maximum and most effective force, therefore improve athlete performance and reduce injuries in sport. Increasing explosive power plays a crucial role in most power-speed sports, including judo. Therefore, the use of explosive power training such as plyometric training can improve the performance of judo athletes.

Objective: The aim of this study was to investigate the effect of six weeks of plyometric training on the upper and lower torso explosive power of elite judokas.

Methodology: In this study, 22 elite judokas (age: 20.12 ± 1.4 and weight 69.63 ± 5.7 kg) were randomly divided into control and training groups. Before training, upper and lower body explosive power was measured using a medicine ball throw test and a vertical jump test, respectively. Then, the training group performed plyometric training for six weeks and the control group continued their normal training. After training, the explosive power of the upper and lower body of the control and training groups was measured again. Significant differences in data average were analyzed using t-test at the level (p≤0.05).

Results: The results of Kolmogorov-Smirnov test showed that the research data have a normal distribution (p>0.05). Therefore, the results of t-test show that the upper body explosive power in the training group is significantly higher than the control group (t (20) = -9/216, p<0.05). Also, the lower body explosive power in the training group is significantly higher than the control group (t (20) = -7/016, p <0.05).

Conclusion: Plyometric training can increase the explosive power of upper and lower body of elite judokas. As a result, this type of training can be used to develop and improve the explosive power of elite athletes in a short time by observing safety principles and training science principles. Therefore, elite athletes and coaches, especially elite judokas who need explosive power, are advised to use plyometric exercises in addition to their normal training to improve their athletic performance.
