“…En varios estudios [6][7][8]10,17,18 se muestra que los jugadores no fueron capaces de reemplazar las pérdidas de agua por sudoración mediante la ingesta de agua ad libitum, como en el presente ensayo, mientras que otro estudio 24 obtuvo que una ingesta de líquido previamente prescrita se tradujo en una mayor ingesta por parte de los jugadores. Por lo que la prescripción de una ingesta determinada podría llegar a conseguir una mayor ingestión de agua y así disminuir la tasa de deshidratación durante la práctica deportiva.…”

“…En cuanto a la variación del porcentaje del peso inicial respecto al final, se obtiene una variación menor (0,63%) respectos a estudios anteriores 10,11,17,18,24 . Uno de los factores que pudo haber contribuido a esta menor variación pudo ser la pauta de ingesta de una cantidad de fluido previo al entrenamiento, aunque se necesitan más investigaciones para corroborar esta relación.…”

Introducción: Se conoce que la hidratación juega un papel crucial en el desempeño deportivo. Pero un gran número de estudios que evalúan la hidratación durante la práctica de fútbol han demostrado que gran cantidad de jugadores presentan un estado de deshidratación previo a la práctica de este deporte y que la mayoría de los futbolistas no son capaces de reponer la pérdida de agua por sudoración con la ingesta ad libitum.Objetivos: Analizar el consumo de agua ad libitum, el balance hídrico, la sensación de sed y la tasa de esfuerzo percibido en una muestra juvenil de jugadores de fútbol durante una sesión de entrenamiento.Material y Métodos: 57 jugadores de tres equipos de la categoría juvenil de la cantera de un club de fútbol participaron voluntariamente en el estudio mediante la recogida del peso al inicio y al final del entrenamiento, la sensación de sed, la tasa de esfuerzo percibido y la cuantificación del agua ingerida. Se utilizaron estadísticos descriptivos, correlaciones y análisis de proporciones.Resultados: La ingesta media del global de futbolistas estudiados fue 844,74±351,95mL y la pérdida media de agua corporal de 1274,56±385,82mL. Una tasa de deshidratación media respecto al peso inicial del 0,63%. Se obtuvo una puntuación media de 2,81±1,32 en la escala de sensación de sed. Discusión y conclusiones:Se obtienen tasas de pérdida de agua corporal similares a estudios previos. Los futbolistas no fueron capaces de reponer la pérdida de agua mediante la ingesta de líquido ad libitum, por lo que la ingesta de una cantidad pautada previamente podría llegar a ser de gran ayuda.

“…A motor action which presents speed higher than the dislocation as walking, but shorter than dislocation as trotting, is the dislocation backwards When the time of these three motors actions are summed up (walking, trotting and backwards), it is (20) English League 1st Division 778 (31-48) 11.534 ± 748 Weston et al (21) Italian Championship 6th and 7th Divisions 20 22.6 ± 2.4 11.394 ± 697 Ardigò (22) World Cup Under-17 12 33.4 ± 3.8 11.059 ± 935 Malloet al (8) English League1st Division 254 40.1 ± 4.9 11.622 ± 739 Weston et al (23) Paraná State Championship -34.4 ± 4 9.131 ± 256 Da Silva et al (24) São Paulo State Championship -27.3 ± 4.7 10.034 ± 841 Da Silva et al (24) Paraná State Championship A Series 13 38 ± 1.1 9.189 ± 125 Da Silva et al (25) English League 1.269 (22-49) 11.770 ± 808 Weston et al (26) verified that referees remain from 60 to 90% of the total time of the game using them (4,5,11,13,15) .

Introduction: In order to control and select the referees for performance in professional soccer, the Fédération Internacionale de Football Association (FIFA), considered the accomplishment of physical tests. However, the initial proposal of evaluation suffered modifications with the passing of the years, and the current model seems not to be ideal to evaluate the referees, in accordance with the physical profile requirement demonstrated during the games. Objective: Therefore, the objectives of this study were: to identify the physical load of soccer referees in official games and to determine the physiological demands associates to the physical effort during the official games; and to analyze the current model of physical evaluation of the soccer referees. Conclusion: Referees cover an average of 10,000 meters during a game, being most of the time done with activities of low intensity. The activity profile is intermittent and the energy demand has predominance of the aerobic system, with important participation of the anaerobic system. The current tests applied are not compatible with the standard of physical requirement of a referee during a soccer game.

“…Referees and players possess different types of group due to difference in their responsibilities during a match that requires specific physical and psychological attributes (Da Silva et al, 2011). After time has passed, the number of distance that is covered by a referee in a single match of football have steadily increased proving that this population must obtain a considerably different physical conditioning program in order to suit their match fitness.…”

“…Recently, several researches had investigated soccer referees on how they moved and how much they ran during match (Da Silva et al, 2011). These by thorough analysis of using digital technology such as software and hardware make the soccer match analysis are practical and viable for practitioners and researchers respectively (Liebermann et al, 2002).…”

Adnan R, Muzayin N, Sulaiman N. Analysis of Movement Pattern among Referee in 2012 Malaysian Cup. J. Hum. Sport Exerc. Vol.8, No. Proc3, pp. S642-S650, 2013. This study is to determine the contributing factors of the movement patterns toward the total distance covered by the football referees during the Malaysia Soccer Cup 2012. Seven (7) of referees who officiated the 2012 Malaysian Cup matches were been chosen into this study. All seven matches from the tournament were recorded using Astro beyond decoder and were coding with SportCode Elite Software on the selected performance indicators (P.I) as main movement patterns variables. This movement patterns were categorized as forward walking, forward jogging, forward running, standing, backward walking, backward running and sidestep running. The results analyze the frequency and the total time from the executed movement patterns for correlation and regression analysis by using the Pearson correlation and linear regression test respectively. The Pearson correlation test have shown that there is significant correlation between three movement patterns and the total distance covered by the referees which are sidestep(r= 0.97, p=0.000, p<0.01), forward walking (r= 0.930, p=0.002, p<0.01), and forward running (r= 0.807, p=0.028, p<0.05). The linear regression test have shown a positive correlation between contributing factors of the movement patterns towards the total distance covered by the football referees where the total distance covered result is 132.161 + 2.012 (sidestep) -4.575 (forward walking) + 0.570 (forward jogging) -2.940 (forward running) + 1.404 (backward walking) + 3.328 (backward running). Hence, this study found that movement patterns that performed by referees are contributed towards the total distance covered by football referees during a match. Thus, this study can give added values to Football Association of Malaysia (FAM), to consider the three significant movement patterns in designing physical fitness criteria for the referees).
