ANALYSIS COMPETITIVE ACTIVITY OF ISKA KICKBOXERS IN THE DISCIPLINE OF K-1

. The article for the first time considers the results of the analysis of the competitive activity of ISKA kickboxers in the discipline K-1. Quantitative and qualitative indicators of technical and tactical actions in attack and defense are revealed. In terms of efficiency, kicks and knees exceed the corresponding rates of punches. Protective actions by moving are used much less than protections by the hands, by the legs and by the torso

Statement of a scientific problem.Kickboxing ISKA is a martial art and a sport recognized in Ukraine, the essence of which is to inflict punches and kicks and protect against them.Kickboxing competitions take place in the following disciplines: semi-contact, light contact and solo compositions are held on the tatami; full contact, low kick, oriental or (K-1) -in the ring [7].According to some experts, the ring discipline K-1, in which the rules allow the use of punches, kicks and knees, has the greatest prospects for development in both amateur and professional kickboxing [3,7,10].Knowledge of the structure of competitive activity and training of athletes, taking into account the general patterns of sportsmanship and individual characteristics of the athlete is the basis for determining progress in sports [1].Competitive activity reflects the features of technical and tactical skills of athletes in martial arts [1,5].

Analysis of recent research and publications. Analysis of competitive activity
by the method of Frolov allows to determine the level of technical and tactical preparedness of athletes, by obtaining quantitative and qualitative characteristics of the duel, by deducting more than 20 different coefficients that characterize the fighting.Based on this method, competitive activity was analyzed by Ostyanov, Gaskov in boxing [4], Sagat Noi Koklam in Thai boxing Muay Thai [6], in kickboxing Stepanov dealt with this issue [8], Kleshchev and others [3].Therefore, the analysis of the effectiveness of technical and tactical actions in the ring discipline of K-1 kickboxing ISKA, taking into account the fact that the rules in the discipline of K-1 allow knee strikes, we consider relevant and necessary topic [2,9].
The aim of the research.To determine the quantitative and qualitative indicators of technical and tactical actions in the attack and defense of kickboxers of the discipline K-1 by analyzing competitive activities.
Research methods.Analysis and generalization of data of scientific and methodical literature, video recording of competitive duels, pedagogical observation, expert analysis of video materials, methods of mathematical statistics.
Organization of the research.In this work were analyzed semi-final and final fights of adult kickboxers who took part in the World Kickboxing Championship ISKA, held in 2018 in Kyiv (Ukraine) and the World Kickboxing Championship ISKA 2019, which was held in Cork (Ireland).60 fights were analyzed, including 20 finals, between highly qualified kickboxers.A group of qualified experts of three people (top coach, international judge, master of sports of international class; concordance coefficient is W = 0.81) analyzed videos of competitive matches recorded with a CanonLegria HF R306 camera (frame rate 31 frames / s).
On the basis of the analysis of competitive activity the quantitative and qualitative indicators (coefficients) characterizing technical -tactical actions in attack and in protection of kickboxers in discipline K-1 are calculated: 1.The number of strikes performed on average per round -strikes in total, effective; punches, kicks, knees strikes.
2. The number of defensive actions performed on average per roundappropriate defenses, with the help of arms, torso, movements and with the help of legs.
3. The coefficient of efficiency in the attack -(the ratio of strikes to the total number of strikes), the coefficients of effectiveness: attacks, counterattacks in response, counterattacks towards, strikes, punches, kicks, knees strikes.4. Coefficient of effectiveness in defense -the ratio of the number of appropriate defenses to the total number of strikes of the opponent.
Using the Statistics 6.0 package, the arithmetic mean value (M) and the standard error (m) of quantitative and qualitative indicators of competitive activity were calculated.
Results of the research.According to the results of the study, kickboxers in the discipline K-1 on average per round perform 32,4 ± 1,4 strokes (this indicator characterizes the density of the duel), among which 13,0 ± 0,6 are effective (coefficient of effectiveness of strokes -0,4 ± 0,02).The results of the analysis of technical and tactical actions in the offensive are shown in table 1.
Experts have determined the percentage of punches, kicks and knees in kickboxers.On average per round, the number of punches is 50%, kicks -32%, knees -18%.These facts indicate the focus of kickboxers on the harmonious use of shock technical and tactical actions of the upper and lower extremities of kickboxers in the discipline K-1.According to the study, the average number of punches per round in the discipline K-1 is 15,6 ± 1,1, the result was 5,0 ± 0,4 strikes (the coefficient of effectiveness of punches is -0,32 ± 0,02).The results of the study revealed quantitative indicators of the percentage of direct, jabs (crosses), hooks and uppercuts strokes, which has the form of 55 : 38 : 7 (%).Most straight strikes indirectly indicate that hand strikes are used mainly from a long distance.ISKA kickboxers are the least likely to use uppercuts in the K-1 discipline.In our opinion, this fact is due to the fact that in close combat, athletes use knee strikes with and without grip instead of uppercuts.
Analysis of the results of the research revealed that in the discipline of K-1 kickboxers often use round-kicks, with the highest efficiency.Knee strikes, which clearly distinguish K-1 from other disciplines of kickboxing, in our opinion, are the hallmark of this section.According to the results of the research, 75% of kickboxers strike with their knees with holding the opponent's head (neck, shoulders) with one or two hands.

According to the results of the analysis of competitive activity, it was found that every third combat action (attack, counterattack) contains a knee strike, and in every fourth combat action a knee strike is performed with the capture of the enemy, which in our opinion indicates the importance of using this technical and tactical action in the discipline K-1.
Analyzing the competitive activity, it was found that the number of attack actions on average per round in the discipline K-1 is equal to 10,3 ± 0,8, effective were 5,0 ± 0,4 attacks (the coefficient of effectiveness of attacks actions -0,49 ± 0,03).
Counterattacking combat operations were registered by specialists in two versions, as a counterattack in response and a counterattack towards.The number of counterattacks towards in response on average per round is equal to 4,9 ± 0,4, effective were 2,6 ± 0,3, therefore, the coefficient of effectiveness of counterattack towards in response is equal to -0,53 ± 0,04.The number of counterattack towards on the average is 3.3 ± 0.3 per round, 2.2 ± 0.3 counterattacks were effective, the coefficient of effectiveness of the counterattack is 0.67 ± 0.06.The average ratio of combat operations per round is as follows: 55.7% -offensive actions, 26.5%counterattacks in response, 17.8% -counterattacks towards.
Thus, according to the results of the analysis of competitive activity of kickboxers in the discipline K-1, it is possible to conclude that in fights in this section athletes equally use attack and counterattack tactical actions, although the coefficient of counterattack efficiency is much higher.
The analysis of competitive activity allowed to establish that the coefficient of effectiveness of defensive actions on average per round is equal -0,57 ± 0,01.
Moreover, kickboxers in the discipline K-1 are most closely protected from strikes to the head (10,6 ± 0,9 effective protective action against strikes to the upper level (head), the coefficient of effectiveness of protective actions -0,7 ± 0,03).Also on average per round, kickboxers perform 6,4 ± 0,4 of the effective protective action against strikes to the middle level (in the torso) with a coefficient of effectiveness of protective actions -0,53 ± 0,02.
The results of the study allowed us to conclude that the lower level is the most vulnerable to blows.At 3,2 ± 0,2 effective kicks along the thigh on average for a round of effective protective actions against kicks to the lower level was found only 1,5 ± 0,4 (coefficient of effectiveness of protective actions -0,29 ± 0,04), which indicates the technical difficulties to perform protective technical and tactical actions against kicks along the thigh.
Thus, we believe that one of the most important factors determining the effectiveness of competitive activities in a fight of kickboxers is the level of technical and tactical preparedness, due to the individual characteristics of the
