Objective: To compare results of the 30-15 IFT intermittent fitness test between different playing positions in a professional soccer team and to provide reference data for similar populations. Methods: 29 adult soccer players (21.83 ± 3.11 years) from a professional club in Chile. Results: Goalkeepers had a mean and standard deviation in the VIFT of 19.9 ±0.8, defenders 21.3 ±1.2, forwards 21.4±1.6, wingers 21.4 ±0.8 and midfielders 22.1 ±0.5. There were large significant differences (F=2.458; p=0.073 and η²p=0.291), specifically between goalkeepers with fullbacks and midfielders. For VO2máx goalkeepers had a mean and standard deviation of 53 ±3.1, defenders 56.1 ±1.9, forwards 56.9 ±2.9, wingers 56.3 ±2.3 and midfielders 58.1 ±0.7. There were large significant differences between groups (F=3.085; p=0.035 and η²p=0.34), specifically there were differences between goalkeepers with forwards and midfielders. Conclusion: There are differences in physical performance between players according to playing position, being wingers and midfielders who presented significant values in comparison with goalkeepers and in estimated VO2máx., forwards and midfielders showed significant differences with goalkeepers.Objetivo: Comparar resultados de la prueba de aptitud física intermitente 30-15 IFT entre diferentes posiciones de juego en un equipo de fútbol profesional y ofrecer datos de referencias para poblaciones similares. Método: 29 jugadores de fútbol adultos (21.83 ± 3.11 años) de un club profesional de Chile. Resultados: Porteros tuvieron una media y desviación estándar en la VIFT de 19.9 ±0.8, defensas 21.3 ±1.2, delanteros 21.4±1.6, laterales 21.4 ±0.8 y volantes 22.1 ±0.5. Hubo diferencias significativas grandes (F=2.458; p=0.073 y η²p=0.291), específicamente entre porteros con laterales y volantes. Para VO2máx los porteros tuvieron una media y desviación estándar de 53 ±3.1, defensas 56.1 ±1.9, delanteros 56.9 ±2.9, laterales 56.3 ±2.3 y volantes 58.1 ±0.7. Hubo diferencias significativas grandes entre grupos (F=3.085; p=0.035 y η²p=0.34), específicamente hubo diferencias entre porteros con delanteros y volantes. Conclusión: Existen diferencias en el rendimiento físicos entre jugadores según posición de juego, siendo los laterales y volantes quienes presentaron valores significativos en comparación con los porteros y en VO2máx. estimado, delanteros y volantes mostraron diferencias significativas con los porteros.
