Biomechanical Indicators of Competitive Activity in Mas-Wrestling

摘要

The paper assesses the possibilities of using biomechanical indicators of competitive activity in mas-wrestling (the relative position of stick fluctuation zones and the general center of mass (GCM) of two athletes' bodies system, the angle changes in the knee and hip joints) to determine the technical and tactical advantages (tactical efficiency, coordination of movements and economy of technical actions) of athletes. The discrepancy between the stick position zones and the general center of mass of the two-body system is revealed. The most significant is the ratio indicator of positions number of the general center of mass of bodies system to the number of stick positions on a certain side, reflecting the tactical efficiency of an athlete. In the winner of the fight, it was 5.5 times higher than in the loser. Tactical efficiency, in turn, is determined by the coordination of athlete's body links movements in the knee and hip joints. In the winner, the bending of the torso is synchronized with the bending of the legs and vice versa. The loser does not have such consistency, he either extends his legs, not reinforcing it by extension of the body, or extends the body without the help of the legs. Economy of technical actions reflects the modulus of difference fluctuations in the angles in these joints. The average value of this indicator for the loser is 15.2 ± 11.98°, for the winner - 8.4 ± 6.65°, almost 2 times lower (p < 0.05).
