Perception of Using VAR Technology in Football After Completion of Training and Education and Experiences of Croatian Video Assistant Referees (VARs) and Assistant VARs (AVARs)
By introducing VAR technology in football the process of decision making during the game has been made easier for referees on the field, where they coordinate with a team of experts that are inside the VOR room. Additional education and practical experience of all participants involved in this process is required for the application of VAR technology in football in order to ensure the accuracy and adequate speed of the decision making process. This paper shows the results of the research on the perception(s) of using VAR technology in football of Croatian Video Assistant Referees (VARs) and Assistant VARs (AVARs) that received training and education regarding the use of VAR technology on the football field. The results and findings of this paper can help all those who want to contribute to the advancement of application and functionality of VAR technology in football.

The use of video assistant referee (VAR) technology in football match management
The video assistant referee technology (VAR) is one of the most important modern electronic technologies used in the management of football matches at the international level, which has been adopted internationally in the most important world championships. The aim of the research is to identify cases of using video assistive judgment technology in the Spanish League and for the teams that won the first three places for the season (2019 2020) The researcher used the descriptive approach. The research sample was the Spanish League matches for the season (2019 2020) (Real Madrid, Barcelona, and Atletico Madrid) The researchers concluded that the assistive video referee technology has a great impact in determining the results of matches in a fair manner and without relying on the assessment of the personal situation by the referee, and that all teams benefit from the assistive video referee technology and that no differentiation occurs between teams because of its use. And the introduction of video assistant refereeing technology in the Iraqi league will have a positive impact on the accuracy of arbitration decisions

Video assistant referees (VAR) The impact of technology on decision making in association football referees
ABSTRACT The use of technology has been proposed to improve decision making in sport officials. The implementation of the video Assistant Referee (VAR) in association football is one example of how technology can be used to assist decision making, although its impact remains unknown. In 2195 competitive football matches across 13 countries, the VAR conducted 9732 checks for potential match changing incidents, with the median duration of a check being 22 seconds. The checks resulted in a total of 795 reviews, with a median duration of 62.0 s for on field reviews (N 534) and 15.0 s for VAR only reviews (N 261).We report that the predictive odds for making the correct decision after VAR intervention were significantly higher than for the initial referee's decision, with accuracy increasing from 92.1% to 98.3% Findings have implications for the current debate about the introduction of technology in association football and may help set guidelines regarding the use of technology across other sports and professional domains.

The aim of the work to establish motor skills peculiarities in young football players (aged 13 to 14 years) Methods of the research: Tests for speed and velocity and Tensodynamometry (Radziukynas 1997) Average height of football players is 168 cm, their body mass 55.84 kilos, BMI 19.58. The vertical body movement speed in two foot take off of the players is 2.49 m/sec, running results: in 10 m run 1.88 sec (5.31 m/sec) in 20 m run 3.31 sec (6.04 m/sec) in 30 m run 4.68 sec (6.41 m/sec) jumping in hexagon area result 17.16 sec, angular movement result 2.35 m/sec. Individual movement skills are expressed by kinematic and kinetic indices of interaction with support, such as: squat time (0.348 sec) take off duration (0.249 sec) squat speed (1.02 m/sec) squat depth (19.5 cm) reactivity of legs' muscles (22.1 Hz) jump height (31.4 cm) absolute power of take off (1555 N) relative capacity (28.5 W) Football players do not experience fatigue performing intense two foot vertical jumps, in average 45 jumps in 30 sec. Correlation analysis of all movement directions kinematic and kinetic indices relation significance highlighted the main indices which most objectively allow evaluation, prognosis, and correction of various directions movement level and abilities of young football players. Alteration of these indices' significance interrelation shows peculiarities of athletes' body functional systems' adaptation to training loads, also serves as an effective methodical direction in improving preparation of young football players.

A Step to VAR: The Vision Science of Offside Calls by Video Assistant Referees
The Video Assistant Referee (VAR) system has had a major impact on decision making in professional association football. However, offside decisions remain a major area of dispute and debate, with over 34 goals ruled out in the first season of VAR in the Premier League. Evidence in vision science points toward two problems with the application of the offside law in VAR, due to their use of a live TV video feed in reviews. First, due to physical and perceptual limits on spatial resolution, there is a significant probability that the spatial positions of the ball and players as judged by VAR will be several centimetres to one side of their true positions. Second, the 50 Hz TV update rate means that judgements of the time of contact between player and ball will on average be 10 ms too late, which translates into an increased likelihood of offside calls in fast moving play. Suggestions are made for how to compensate for these problems during decision making.

VAR SISTEMININ 2018 2019 SEZONU SUPER LIG FUTBOL MACLARINA ETKISININ DEGERLENDIRILMESI
Football, which is one of the most important sport branches of the world, has been adopted and given attention by people and it has become an indispensable tool for countries in introducing and highlighting their culture. It is important for football, which has become a professionalised commercial source of income through becoming an industry over time, and therefore football matches, to be followed carefully and it is also important to analyse every detail of matches and to minimize errors. From this point VAR system, which is a product of the team work created with the support of digital platform and which is expected to help the referee during football matches, has been developed. In this context, retrospective study model, which is one of the subtitles of observational study, was used so that evaluations could be made on football matches played by using the VAR system in the study. The information obtained was discussed and interpreted in line with the purpose of the study. Accordingly, in addition to the views about and reflections of the system in the world and Turkey, the effects of VAR system on the matches played by 2018 2019 Turkey football super league teams were examined. According to the results obtained in the study, it can be said that mostly there is a consensus about the continuation of the system although VAR system has faced reactions partially in the world and Turkey. While it was found that Bursaspor was the team which lost the highest number of points as a result of being negatively affected by the decisions taken with VAR system in 2018 2019 Turkey football super league; Antalyaspor was not affected by VAR system in terms of points. In addition, thanks to the VAR system, Evkur Yeni Malatyaspor qualified for the European cups by getting a place in the top five rankings.
