Objective of the study was to conduct a comparative analysis of biomechanical characteristics of the back and chest throw techniques to determine the most effective ones for male wrestlers.
Methods and structure of the study. The study involved 10 qualified male sambo wrestlers including 4 first-rank athletes, 3 candidate masters of sports and 3 masters of sports, who gave their written informed consent to participate. The subjects were to throw a 32.6 kg mannequin dressed in a sambo jacket over the chest: back throw carried out by gripping the sleeves and the lapel and chest throw carried out by gripping the sleeves and the belt under the shoulder of the mannequin. After the warm-up and trial attempts, the wrestlers were to execute three throws that were assessed. All throws were performed with individual maximum strength and speed. The biomechanical characteristics of both the mannequin and athlete were obtained with the help of the Qualisys optical motion capture system consisting of 8 high-speed Oqus 300+ infrared cameras. The cameras were synchronized with two AMTI dynamometric platforms. The video shooting frequency was set at 200 frames per second. The data obtained were processed using the "Qualisys Track Manager software.
Study results and conclusions. Based on the comparative analysis of the back and chest throw technique biomechanics, the back throw should be recognized as the most effective one. It is executed faster and can be evaluated higher by the judges. When throwing the opponent over the chest, the attacker falls. Consequently, the moment of gravitational force of the athlete’s body adds to that of the mannequin. But this does not give an advantage in terms of the throw execution speed.

Keywords: sambo wrestlers, back throw, chest throw, biomechanical characteristics.
