Abstract:
The aim of the study was to compare the relative running demands (m·min-1), among different soccer players positions, coded by an absolute threshold vs. an individualized threshold based on splits of 10% of peak velocity, during friendly games, with the same tactical system and monitoring with a GPS. To this end he had 20 players on a semiprofessional soccer team. All players were monitored with a unit GPS (15 hz SPI-pro W2b, GPSport, Canberra, Australia). They are measured peak velocity with a sprint of 40 m, and its activity in 4 friendly matches. The player’s activities were coded into five absolute speed thresholds and ten individualized speed thresholds. The absolute speed thresholds were: Very low intensity running (VLIR: 0-7 km·h-1), Low intensity running (LIR: 7-13 km·h-1), medium intensity running (MIR: 13-18 km·h-1), high intensity running (HIR: 18-21 km·h-1), and very high intensity running (VHIR: 〉 21 km·h-1). The individualized thresholds were from 〈 10%, 10-20 %, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, 80-90%, and 〉 90% of peak velocity (PV). Variables are presented as the mean (± SD), and the estimated precision is indicated with 90% confidence limits (CL). In addition to the analyses for statistical significance (i.e., paired t-tests), possible differences between players’ position was analysed (pairwise comparisons) for practical significance using magnitude-based inferences. The 30% of players get 80-90% of its peak velocity in match and 2.5% reaches 90-100% of its peak velocity.Resumen. El objetivo del estudio fue analizar las demandas de carrera ent jugadores de fútbol con diferentes roles empleando tecnología GPS, analizando y comparando sus desplazamientos durante partidos amistosos en base a un umbral absoluto, frente a un umbral individualizado al perfil locomotor del jugador. Para ello se les valoró su pico máximo de velocidad realizando un sprint de 40 m, así como su actividad locomotora en 4 partidos amistosos. Los desplazamientos de los jugadores codificaron en cinco umbrales de velocidad absolutos y diez umbrales de velocidad individualizados. Los umbrales de velocidad absolutos fueron: carrera de muy baja intensidad (VLIR: 0-7 km·h-1), carrera de baja intensidad (LIR: 7-13 km·h-1), carrera de intensidad media (MIR: 13-18 km·h-1), carrera de alta intensidad (HIR: 18-21 km·h-1), y carrera de muy alta intensidad (VHIR: 〉 21 km·h-1). Los umbrales individualizados en base a su pico de velocidad máxima (PV) fueron: 〈 10%, 10-20 %, 20-30%, 30-40%, 40-50%, 50-60%, 60-70%, 70-80%, 80-90%, and 〉 90% del PV. El 30% de los jugadores consiguen el 80-90% de su pico de velocidad en partidos y el 2.5 % alcanza el 90-100 % de su pico de velocidad.
