ABSTRACT
Soccer is a sport of various motor actions, where the reception of the ball is classified as a control action at different heights, speeds and angles. The player must have the ability to receive the ball in order to generate a different action: a pass, shot or dribble; its optimization implies greater probabilities of technical-tactical performance. In this sense, the objective of the research was to biomechanically analyze the mid-height reception technique in professional and amateur soccer players using video analysis as a measurement method. The research was descriptive-explanatory of correlational order, four variables of the motor movement (D: distance covered; AM: maximum acceleration; VM: maximum speed and AF: amplitude of the femorotibial joint) are analyzed through video-analysis with Kinovea . Five professional players (group 1) and 15 amateur players (group 2) were studied. The amateur soccer players presented a higher mean in all the variables studied, "D" (group 1: 72.17cm; group 2: 101.27cm; p=0.001), "AM" (group 1: 61.84m/s 2 ; group 2: 101.73m/s 2 ; p=0.000), "VM" (group 1: 8.18m/s; group 2: 12.55m/s; p=0.000) and "AF" (group 1: 62.6°; group 2 : 75.2°; p=0.002), which behaves significantly different in all cases. The biomechanical analysis carried out on professional and amateur soccer players, in the technique of receiving the ball at mid-height, concludes that amateur players require greater technical improvement, regardless of their experience in competitions.

INTRODUCTION
In sports biomechanics, the application of mechanics has been determined as an study of the movements made by the athlete in the execution of technical gestures, which becomes one of the essential premises of the sports training management process, and is included in the specific soccer process (Vizcaíno, Cortizo, 2020; Da Silva et al., 2019). Its objective is to evaluate the competitive technique, which optimizes its performance and generates new forms of training (Perdomo et al., 2018).
In the last decades of this century, soccer and its form of training have achieved constant evaluation; this has made the methodologies more in line with the needs of increasing or maintaining high sports performance (Calero, 2019; Morales, 2014; Morales, 2018). This evolution has largely been a reflection of what is happening with the new world and new body movement research, where soccer as a university sport is often studied with high intensity. This leads to improving the processes of acquisition and improvement of the specific motor habit, such as the improvement of driving technique, hitting and reception. These processes are based on biomechanical analysis or the improvement of determining physical capacities (Carbo et al., 2019; Silva, Ayala, 2021; Flores, Ramírez, 2019; Ruano, Losa, 2021).
When studying soccer, it must be considered that performance is determined by the multifactorial structure of elements that interact in very complex ways (Scharfen, Memmert, 2019). These factors in isolation are not decisive in the performance of the equipment, but as each of the different elements influence the performance in an integral way; is that sport improvement can reach its maximum expression.
All those technical executions where there is a predominance of power capacity, speed and optimal quality are decisive to provide effective solutions when facing the different game situations posed by the competition (Lucas, 2020). It will also be necessary to consider that it is a socio-motor sport; therefore, the performance will not only depend on the actions of the team itself, but also on the type of actions of the opponent (Calero, 2019; Barrero, Lazarraga, 2020).
The reception in soccer is the action of controlling the ball completely. In competition, the player will receive the ball numerous times at different heights, speeds, and angles (Carbo et al., 2019). A player must be able to receive the ball quickly, being able to generate a new action: pass, shot or dribble . Players within the field of play can use different parts of the body to receive the ball, players use their feet, thighs, chest and head (Rodríguez, 2021).
In the teaching-learning process based on explanatory-demonstrative methods, as is the case with sports, there is a need to have ideal motor patterns, which is the basis for error correction, and therefore the optimal acquisition of motor habits specific. In this sense, the purpose of this research is to biomechanically analyze the mid-height reception technique in professional and amateur soccer players.
MATERIALS AND METHODS
The present research has a descriptive-explanatory orientation of correlational order, selecting under a non-probabilistic intentional sampling five professional soccer players from the SD Aucas reserve team (group 1: professionals; five subjects), in addition to five players from the soccer team from the University of the Armed Forces-ESPE, and ten players from the soccer Angamarca Neighborhood League (group 2: amateurs; 15 subjects). The age range of the study is considered to be between 20-30 years.
The studied variables were evaluated with the Kinovea program, its dual screen mode is used for this purpose, which allows the simultaneous comparison of two executions. The video-analyses must be synchronized, which makes a common movement comparison possible. Movements of the coxofemoral joint during mid-height reception were recorded . The five professional soccer players and all amateur soccer players practiced this discipline for several years and uninterruptedly, with experience in different competitions.
The procedure used in the research for data collection was the video-graphic method, with the biomechanical analysis program mentioned, for subsequent statistical analysis of the data, the SPSS v.15.0 software for Windows was used.
The biomechanical variables studied will be:
RESULTS AND DISCUSSION
Table 1 shows the results achieved in each variable analyzed, both in the professional and amateur groups, obtaining the mean values for later comparison (Table 1).
Table 1. - General data
Table 1 shows the different individual values regarding the execution of the reception technique at mid-height, where the mean or average value obtained in the group of professionals for the variable "maximum acceleration" (MA) was established in 72.17cm. Meanwhile, the Acceleration (A) obtains an average of 61.84m/s2 and the speed (V) an average of 8.18m/s. On the other hand, the angle of the femorotibial joint (FA) establishes an average of 62.6° .
On the other hand, the mean values achieved as part of the group of amateur soccer players in the mid-height reception technique established a value of 101.27cm for the "distance" variable. So, it is inferred that it is higher than the average established in group 1; therefore, the Mann-Whitney U Test (Table 2) determined significant differences in the data obtained by the independent groups (p=0.001). The foregoing shows that the distance traveled by the professional player is in consideration and in relation to the other components of the technical-tactical action, an aspect related to the precision and optimization of the motor component.
In the case of acceleration, group 2 obtained an average of 101.73m/s2 , much higher than the average established by the group of professionals; hence it prevails, with a significant difference (p=0.000). This difference is also seen in the "speed" variable (p=0.000), since the mean of group 2 was established at 12.55m/s; which is much higher than that established in the professional soccer players studied. The foregoing is indicative of a better control of the body segments in professional players, given that speed and acceleration are mainly conditioned to motor improvement. This shows an increase in accuracy and energy savings. On the other hand, the speed exerted by an amateur soccer player is inadequate, since it exerts a damping force on the ball that does not allow it to be fully controlled, an aspect that can affect a new technical-tactical action.
In the case of the articular amplitude of the femorotibial joint, the group of amateur soccer players established a mean of 75.2°, an amplitude also higher than that established in professional soccer players; which is significantly different (p=0.002). The foregoing shows that the angle formed by the femorotibial joint must be in a range of 50 to 65°; It is considered that professional players, by maintaining this range of angles, achieve better control of the ball. As a consequence, a more effective reception is obtained in the mid-height of the ball (Table 3).

The results found in the study reveal that the maximum acceleration with which a professional soccer player exercises the reception technique at mid-height reaches 73.46 m/s2. The acceleration of an amateur soccer player reaches a maximum of 115.60 m/s2, for which we refer to the statements on the Barca Innovation website (2018). Acceleration is one of the metabolic activities that places a demand that increases the energy expenditure of the competing activity, and therefore increases muscle fatigue. This is an aspect that is referred to when this acceleration is compared with a displacement at constant speed (Barca Innovation, 2018).
It can be also found references regarding the classification of sports, and how acceleration influences technical action in team and team sports. Acceleration, deceleration and direction changes occur with a very high frequency. Specifically, the literature has determined in soccer how acceleration in 85 % fails to reach a high displacement speed (Miller et al., 2016).
The speed exerted by a professional soccer player is one of the most studied multifactorial abilities. This variable is made up of the speed of reaction and the fast processing of all the information received, of the fast sprints. The player, when controlling the ball, evidences his gestural speed with which he exercises the technique of receiving the ball, short sprints and stops (Palau, 2009).
In the tables analyzed using the SPSS program, it is valued in the average ranges how the speed between professional and amateur players has a considerable range of difference. (Group 1: 12.92; Group 2: 3.20) Professionals have more effective control of their gestural speed, as well as the speed of movement of the body segment, used for the execution of the reception technique at medium height of the ball.
It is understood that each of the analyses of movements in professional soccer carried out by each member in competition highlights the great importance of each action within the competition. In this way, practical applications are achieved against training and sports performance. According to the classification of the joints, the spherical joints (which are in the form of a sphere), are characterized by having a free movement in the direction in which an action is desired. An example of this is the coxofemoral joint and the shoulder-scapular humerus. For this reason, once the average angular of the professional player has been determined, which is 62.6°, importance must be placed on the care of injuries, and how one must work in training to have a better efficiency in carrying out the technique.
Finally, it is considered that the technique of receiving the ball at medium height accompanied by the execution of other techniques (pass, shot, dribble, etc.) could be considered as a set of techniques aimed at the team's offense. In addition, it is recognized as a means by which the tactical part is improved. In this sense, it is proposed to expand the research of the reception technique at medium height in competition; thus, other variables of motor performance that intervene in performance, such as biological maturation, are taken into account. This is an aspect that will allow the study of the technique under study in its full dimension (Pesantez et al., 2020).
CONCLUSIONS
The biomechanical analysis carried out on professional and amateur soccer players in the technique of receiving the ball at mid-height, concludes that amateur players require greater technical improvement, regardless of their experience in competitions.
