Introduction
Solving the problem of increasing the effectiveness of attacking actions in football involves studying the features of building a game in attack by teams of different levels [2; 4; 5; 8; 9; 10]. Of particular interest are the data that characterize the completion of the final phase of the attacking actions by professional teams that participated in the Premier League competitions of the Ukrainian championship and the first league of the championship of Ukraine.
Analysis of the attacking actions of teams of different qualifications is devoted to the research of many specialists [2; 3; 5; 6; 7; 11].
As noted by S. Golomazova and B. Chirva [1], the probability of a goal is primarily determined by the probability that the ball hits the target. Players can more often or less often deliver the ball to the shock position, better or worse act during the attack -in any case, the outcome of the match depends on the accuracy of the final blows.
So, according to observations in the games of high-class teams of 10 strikes on the average, the average hit is only after 3-4 hits.
If the football players perform attacks on the goal in non-player conditions (on a stationary ball, when there is no opposition to the opponent, and if the speed of the strike is not needed), the probability of the ball hitting the target strictly linearly depends on the distance of the strikes. However, the strictly linear dependence of the probability of the ball falling into the goal range from the strike distance is violated when the shots are carried out in a real game, and the greatest deviations are observed where the conditions for striking the target are the heaviest, namely in the area of the penalty area line.
So, according to S. Golomazov and B. Chirva [1], the percentage of ball hits on the target range can vary depending on the level of preparedness and qualification of the players, but in any case, with the increase in the distance of the blows, the accuracy of falling into the target shots will decrease. Calculations show that as the distance is increased by 1 meter, the probability of falling into the target gate in game conditions is reduced by about 3%.
In high-class teams, in some cases, players strike the goal from 1-2 meters, which means that the absolute accuracy of the ball hit the target of the goal in football, obviously, can be achieved when carrying out shots in a very short distance from the goal line -up to 1 meter.
It is established [1] that the probability of getting the ball into the target shots in the game conditions is reduced by approximately 3% with an increase in the strike distance by 1 meter. Thus, the authors argue that when carrying out strikes from 33-35 meters the probability of hitting the target is not more than 5%.
The probability of a goal is determined not only by the probability of the ball reaching the target but also by the actions of the goalkeeper. Of all attacks on the target, not more than 25 meters from the goal (except for head punches from the goal area and penalty shootout), approximately 30% are parried by the goalkeepers regardless of the distance of the blows.
Relationship of research with scientific programs, plans, themes. This work was carried out according to the topic of research of the departments of football and hockey, sports and mobile games and martial arts of the Kharkov State Academy of Physical Culture for 2016-2020 on the theme "Psycho-sensory regulation of the motor activity of athletes of situational sports".
Purpose of the study: to determine the quantitative indicators of effective strikes in the gates in the games of the team "Helios" Kharkov.

Material and Methods of the research
Methods: analysis of scientific and methodological literature, registration of technical and tactical actions, methods of mathematical statistics. The research of the competitive activity of the team of the first league of the championship of Ukraine "Helios" Kharkiv in the season 2017-2018.

Results of the research and their discussion
Data of the tournament table of the first league of the championship of Ukraine show that the team "Helios" Kharkiv after 22 rounds takes 6th place. In this case, the players of the "Helios" team scored 30 goals (on average for the game 1,4 goals) and conceded 20 goals (on average for the game 0,9 goals). Table 1  So, the results of the table show that the players of the "Helios" team scored more goals from 16 to 30 minutes (9 goals), less -from 1 to 15 and from 46 to 60 minutes (3 balls each).
The table shows that the players of the "Helios" team missed more goals in the game segment from 61 to 75 minutes (6 goals), fewer goals -from 31 to 45 (0 goals) and 16 to 30 figure 1. Ratio of goals scored and missed by the team "Helios" Kharkov in different segments of playing time minutes (2 goals).
As a result of the research of the football field areas, from which the effective strikes were made, it was established (Table 2) that 10 players scored from the area of the goal by the players of the Helios team (34,5%).  The results of Table 3 show that the players of the "Helios" Kharkov team from 29 goals of 23 goals (79,3%) scored from the game and 6 goals (20,7%) from standard positions.  Of the 19 conceding goals, 16 goals (84,2%) were omitted from the game and 3 goals (15,8%) from the standard positions by the "Helios" team.

Таble 3 Number of goals scored and conceded from the
Analysis of the goals scored from the standard positions of the team "Helios" Kharkov testifies ( Table 4) that out of 6 goals, 5 goals (83,3%) were scored from 11-meter hits and 1 goal (16,7%) from a free-kick.
Analysis of the goals scored by the foot and the head with players in the games of the first league teams testifies (Table 5) that 16 goals (55,2%) of the 29 goals of the "Helios" team were scored with the right foot, 6 goals (20,7%) -left foot and 7 goals (24,1%) -head.
In turn, the opponents of the "Helios" team of 9 goals scored 9 goals (47,4%) were scored with the right foot, 4 goals (21,1%) -the left foot and 6 goals (31,6%) -head. Table 6 shows the data of the number of assists in the gates from the game in various game situations. It can be seen from the table that out of 23 effective hits from the game of the players of the "Helios" team, 18 goals (78,3%) were scored after transferring the ball from the partner and 5 goals (21,7%) after the ball rebounded from the goalkeeper, defenders, barbells or crossbeams. In turn, out of 16 goals scored by the opponents of the Helios team, 10 goals (62,5%) were scored after the ball was transferred from the partner and 6 goals (37,5%) after the ball was rebound from the goalkeeper, defenders, bar or crossbar. Table 7 shows the quantitative indicators of effective shots in the goal from the game, performed in various ways (first touch, after receiving the ball, after the dribbling).
It can be seen from the table that most of all the goals of the "Helios" team were scored by Kharkiv with the first touch (56,5%). At the same time after receiving the ball, 34,8% of the goals were scored, and after the dribbling was scored 8,7%.
As a result of the analysis of the conceded goals of the "Helios" team, it was found that Kharkiv was missed most of all goals by the players of the "Helios" team after hitting the goal with the first touch (75,0%). After strikes at the gate with a second touch and after the dribbling was played by the team "Helios" was skipped over 12,5%. Table 8 shows the indicators of effective shots in the gate, performed in different conditions (kick the ball from the ground and hit the flying ball). Thus, it is established that the players of the "Helios" team of 29 goals of 20 goals (69,0%) were hammered by the ball from the ground and 9 goals (31,0%) by a blow on the flying ball.
From the table it can be seen that the players of the rival teams from 19 goals of 12 goals (63,2%) were scored after hitting the ball from the ground and 9 goals (36,8%) -after a strike on the flying ball. Table 9 presents the quantitative indicators of effective strikes at the goal, executed by the players of the teams of the first
