Abstract
El número de partidos que los equipos de fútbol disputan a lo largo de la temporada se ha incrementado notablemente en los últimos años. El objetivo de este trabajo consiste en comprobar el efecto de un calendario sobrecargado de partidos sobre el rendimiento físico de los jugadores. La muestra estuvo compuesta por 2.971 partidos de la LaLiga española que recogen el rendimiento físico de 346 jugadores distintos durante la temporada 2018-2019 que disputan dos partidos consecutivos con una recuperación incompleta (<4 días) o completa (>5 días). El rendimiento físico se registró considerando las siguientes categorías: distancia total y carrera a velocidad baja (0–14 km·h-1), distancia de carrera a velocidad media (14,1–21 km·h-1), distancia a alta velocidad (21,1–24 km·h-1), distancia cubierta mediante esprint (>24 km·h-1), número de esprints >24 km/h, número de esprints 21- 24 km/h y número de esprints <21 km/h. Los datos de rendimiento físico se registraron utilizando un sistema de seguimiento computerizado multicámara. Para analizar las diferencias en el rendimiento físico de los jugadores según grupo de edad (17-23 años, 24–27 años, 28-30 años y 31–38 años). se utilizó un modelo mixto lineal. Los resultados sugieren que no existen diferencias significativas en ninguna de las categorías de rendimiento físico o grupo de edad a pesar de disponer de más o menos días de recuperación.
The number of matches played by elite soccer teams throughout the season has increased dramatically in recent years. The aim of the current study was to examine the effect of a fixture congestion on the physical performance of elite players. The sample consisted of 2,971 Spanish LaLiga matches including the physical performance of 346 different players during the 2018-2019 season who played two consecutive matches with incomplete (<4 days) or complete (>5 days) recovery. The following categories were considered: total distance, running distance at low speed (0–14 km·h-1), running distance at medium speed (14.1–21 km·h-1), high speed distance (21.1–24 0–14 km·h-1), distance covered by sprint (>24 km·h-1), number of sprints >24 km·h-1, number of sprints 21-24 km·h-1 and number of sprints <21 km·h-1. Physical performance data was recorded using a multi-camera computerized tracking system. To analyze the differences in the physical performance of the players according to the age group (17-23 years, 24-27 years, 28-30 years and 31-38 years) a linear mixed model was performed. The results suggest that there are no significant differences in any of the categories of physical performance or age group despite having more or fewer recovery days.
