El objetivo de este estudio fue analizar las demandas de los períodos de máxima exigencia condicional (PMI) en partidos de competición oficial de fútbol femenino. 18 jugadoras profesionales (1ª División española, Liga Iberdrola) participaron en este estudio. Las jugadoras fueron analizadas en función del puesto específico: defensas centrales (DC), defensas laterales (DL), medios centros (MC), medios de banda (MB) y delanteras (DE). Se registraron los PMI en 3 ventanas temporales (1, 5, y 10 minutos), durante 15 partidos de competición oficial por medio de dispositivos GPS (10 Hz), y en función de cuatro variables de estudio: distancia total recorrida (DR), distancia sprint (D-SP>21km·h^-1), distancia recorrida a alta potencia metabólica (D-APM>20w·kg^-1) y acceleration density (AD). Además, se valoró el número de ocurrencias sub-máximas (intensidad>85% del PMI) en cada ventana temporal. Las DC y DE alcanzaron valores de DR significativamente menores que MC en todas las ventanas temporales. Mientras que las MC reflejaron valores de D-SP significativamente inferiores a DL, MB y DE en todas las ventanas temporales. Además, las DC obtuvieron valores significativamente menores de D-APM que DL, MC, MB y DE (ventanas temporales de 5´ y 10´). Respecto a AD, las DC, MC y DE alcanzaron valores significativamente inferiores a DL y MB (ventana temporal 1´). El número de ocurrencias sub-máximas en competición fue significativamente menor en las variables D-SP y D-APM en comparación con DR y AD en todas las ventanas temporales. Estos resultados podrían servir como referencia en el diseño de tareas de entrenamiento, que tengan como objetivo la simulación de los requerimientos condicionales de PMI.

Abstract

The purpose of this study was to analyze the demands of maximum conditional requirements periods (PMI) in official women's competition football matches.18 professional players (1ª Spanish Division, Liga Iberdrola) participated in this study. Players were analyzed depending on their specific position: central defender (DC), lateral defender (DL), midfield player (MC), midband (MB) and forward (DE). PMI were registered in 3 time windows (1, 5 and 10 minutes), in 15 official competition matches by GPS devices (10 Hz) and based on four study variables: total distance covered (DR), sprint-distance (D-SP>21km·h^-1), high metabolic load distance (D-APM>20w·kg^-1) and acceleration density (AD). In addition, the number of sub-maximal occurrences (intensity >85% PMI) in each time window was assessed. DC and DE reached values significantly lower than MC in all analyzed time windows. While the MC reflected D-SP values significantly lower than DL, MB and DE in all time windows. Moreover, the DC reached D-APM values significantly lower than DL, MC, MB and DE (time windows 5' and 10'). Regarding AD, the DC, MC and DE reached values significantly lower than DL and MB (time window 1'). The number of sub-maximal occurrences in competition was significantly lower in the D-SP and D-APM variables, compared to DR and AD in all time windows. These results could serve as a reference in the design of training tasks, aimed at simulating of PMI conditional requirements.
