Determination of fighting styles of qualified athletes in modern martial arts based on multidimensional analysis of biomechanical and psychophysiological indicators

Abstract

The purpose of the study is to reveal the fighting styles of combat sambo athletes based on a multidimensional analysis of psychophysiological and biomechanical indicators. Material and methods. 42 qualified combat sambo athletes (age 20-25) took part in the study. The biomechanical analysis of the speed of movement of various points and the value of the angles in the joints during a direct impact was used as a research method. Biomechanical analysis of the technique of a direct blow in combat sambo athletes was carried out using the "Kinovea" program, version 0.8.15. The speed of movement of the fist, shoulder joint, elbow joint, and knee joint was determined. The angles between the shoulder and torso (angle in the shoulder joint), between the shoulder and forearm (angle in the elbow joint), and between the thigh and lower leg (angle in the knee joint) were also determined. Results. 3 clusters (groups) of combat sambo athletes have been identified, which differ in their psychophysiological and biomechanical indicators. The clusters were named as follows: Cluster 1 - "Speed ​​and coordination endurance", corresponds to athletes with a tempo style of fighting; Cluster 2 - "Speed", corresponds to the sportsmen's game style of fighting; Cluster 3 - "Strength and speed", corresponds to athletes with a tempo style of fighting. Conclusions. The results of this study should be used when planning the individual training of combat sambo athletes and to determine the optimal style of conducting a competitive match for qualified athletes.
