Os objetivos do presente estudo foram: a) descrever a demanda física imposta aos árbitros de futebol brasileiros durante partidas oficiais e b) analisar se o nível de aptidão física interfere no desempenho da arbitragem. Os árbitros (n = 11) foram avaliados durante jogos oficiais (n = 21) do campeonato Potiguar 2009. A média de idade foi de 36,36 ± 6,34 anos. A distância percorrida, a velocidade (média e máxima) e a frequência cardíaca (média e máxima) foram registradas durante as partidas. A análise da arbitragem foi realizada por avaliador credenciado pela Federação Norte-Rio-Grandense de Futebol (FNF), seguindo os critérios estabelecidos pela Confederação Brasileira de Futebol (CBF). A distância percorrida, a velocidade e a frequência cardíaca foram, respectivamente, 10,50 ± 0,35 km, 6,43 ± 0,26 km/h (média), 19,84 ± 1,56 km/h (máxima), 162,77 ± 7,44 bpm (média) e 182,22 ± 7,72 bpm (máxima). Foi evidenciada correlação significativa entre o VO2máx e a distância percorrida no segundo tempo (r = 0,517) (p < 0,05). O VO2máx também apresentou correlação com a velocidade máxima de deslocamento (r = 0,506) (p < 0,05). Já o percentual de gordura apresentou correlação negativa com a velocidade máxima no segundo tempo (r = -0,471) (p < 0,05). Foi detectada correlação positiva entre o desempenho da arbitragem e o VO2máx (r = 0,530) (p < 0,05). Com relação ao percentual de gordura, o mesmo apresentou correlação negativa com o desempenho do árbitro (r = -0,496) (p < 0,05). Os resultados do presente estudo indicam que os árbitros de futebol são submetidos à alta sobrecarga física/fisiológica durante as partidas. Os resultados obtidos também sugerem que os parâmetros associados com a aptidão física (composição corporal e o VO2máx) podem interferir no desempenho da arbitragem.

Objective: To analyze the physical effort made by the referees in official games of the Championship of Professional Football Baiano. Materials and Methods: This study is a quantitative and descriptive in nature, taking a sample of a n=30 referees affiliated to Bahia Federation of Football. We collected data related to the distance traveled by the referees during the games through the use of GPS, and for the intensity analysis is collected lacato the blood immediately after the game. Results: We found an average distance of 10.05 km per game. Since the average speed found in the study was 5.9 km/h per game, however, due to the large flashingthat occurs in the game there are situations where the referees get to reach speeds of up to 24 km/h, which is considered the intensity high intensity, which was proved with the collection of lactate, which obtained an average of 5.9 mmol/L. Conclusion: The effort madeby the referee duringthe game, is characterized as an intermittently occurring large variation of the intensity of efforts, may not exceed the anaerobic threshold, thereby requiring a specific training of intermittent character.

Has developed this study aiming to quantify and analyze in terms of time a card (yellow and red), followed by football referees during the games of the Brazilian championship of professional football in 2008. Football is characterized as a physical activity in direct contact with the enemy in the field of play that requires efforts of high intensity and great physical wear. Over the years, the average distances covered by players during a soccer game rose considerably, with it, the football referees in addition to good technical knowledge, they must be good physical condition to monitor the development of the game. These new demands have brought sports to the presence of elements and neutral bodies and agencies to promote, international arbitrators established by the performance in terms of its function and control of violence.The flexible character and interpretation of the rules in their application generates discord on the issue. Data collection was conducted through the official summaries of games where the cards are reported and that time were applied to the athletes that are filed in the Brazilian Football Confederation (CBF).

It is not new that referees, even being the only amateurs in a professional soccer game, are the center of criticism and controversy that revolve around a game. A lack unchecked, an incorrect card, a disallowed goal, a dubious penalty, any markup will result in dissatisfaction on the side of at least one team. Designed to impose and enforce the rules of the game during a match, referees are pressured from all sides, unlike the players, a single mistake can cost them so much. It is a fact that soccer referee must have a technical preparation to command correctly the rules of the game, and a fitness preparation to be always in the best place and to take the right decisions. However, it is also extremely important an appropriate psychological preparation, to the referee knows how to deal with pressure and emotional stress. Thus, this study aims to analyze and to raise through an analytical research, resulting from scientific works records, the importance of having a good psychological level for a soccer referee to be ready to perform his function in the best way. According to the literature revision, it is clear the huge influence of the emotional state in the arbitration performance and in addition, if the psychological skills are worked in referees with proper manner, you only have to add in their arbitration career, leading him to the success in his profession. It is expected that this work can contribute to the studies network about the subject, in order of the psychological part be treated with more emphasis, since today is unusual this type of study in relation to referees

In the current soccer, we have in evidence a great discussion regarding the decisions of the arbitration and how they can interfere in the final result of a match and, consequently, in a championship. The objective of this work is to talk about the influence of referees' decisions in games regarding the psychological effects on soccer players. For this, the methodology of bibliographic review will be used in which will be analyzed works that involve the arbitration, from the pre-game pressure to the aspects within a game, the player, as stress factors present in the life of the athletes and in order to work the referee and player relationship. Within the expected results, we will have negative aspects regarding wrong decisions of the referee, which can bring a high level of stress of the player, can have consequences and reflect on their sporting performance both individually and collectively

Este trabalho aborda o desenvolvimento de uma aplicação móvel para controle de eventos realizados durante uma partida de futebol. Atualmente, em uma partida de futebol os árbitros e membros da mesa arbitrária não utilizam recursos computacionais em tempo real para marcações de eventos que acontecem durante uma partida de futebol. Toda esta ação é conduzida manualmente por ambos, sendo necessária a verificação cruzada das informações entre árbitro e mesa, para a elaboração do documento oficial com o resultado final, a súmula. Assim sendo, foi desenvolvida uma solução computacional com o objetivo de gerenciar toda a partida. Esta solução é direcionada à dispositivos móveis que utilizam o sistema operacional Android.
