Análisis de la distancia recorrida atendiendo a umbrales absolutos y relativos en árbitros de fútbol 11 y fútbol 7 durante partidos oficiales. [Analysis of the distance covered according to absolute and relative thresholds in eleven-a-side and seven-a-side soccer referees during official matches].

El objetivo de este estudio fue analizar la respuesta física de árbitros de fútbol 11 (AC11), asistentes de fútbol 11 (AA11) y árbitros de fútbol 7 (AC7) durante partidos oficiales, atendiendo a rangos absolutos de velocidad y al pico máximo de velocidad (Velmax) individualizado. En este estudio participaron 36 árbitros (25,6 ± 4,7 años) los cuales oficiaron un total de 36 partidos. Se registró la distancia total recorrida y el porcentaje de distancia recorrida a diferentes velocidades de desplazamiento a partir de rangos absolutos y relativos a partir del Velmax alcanzado en una prueba de velocidad de 40-m. Los principales resultados mostraron que AC11 recorrieron un porcentaje de distancia mayor (p0,05) en el rango 80-100% del Velmax individual. Estos hallazgos sugieren que las demandas del juego no solo deberían ir enfocadas a comprender la respuesta física atendiendo a valores absolutos sino también atendiendo al Velmax alcanzado por el árbitro.AbstractThe aim of this study was to analyze the physical response of soccer referees eleven-a-side (AC11), assistant soccer referees (AA11) and soccer referees seven-a-side (AC7) during official matches, using absolute speed ranges and the maximum speed peak. (Peak velocity) individualized. 36 soccer referees (25.6 ± 4.7 years) participated in this study, refereeing a total of 36 soccer matches. The total distance covered and the percentage of distance covered at different intensities were recorded from absolute and relative ranges using the Peak velocity of the 40-m speed test. The main results indicated that AC11 covered a greater percentage of distance (p 0.05) were found in the range 80-100% of the individual Peak velocity. The results obtained suggest that the demands of the game should not only be focused on understanding the physical response taking into account absolute values, but also taking into account the Peak velocity reached by the soccer referee.https://doi.org/10.5232/ricyde2020.06202Referencias/referencesBarbero-Álvarez, J.C.; Barbero-Álvarez, V.; Granda, J., y Gómez, M.
