Positional and Temporal Intermittency in Football: A Metabolic Model Approach

Abstract This study examined positional differences in the intermittent nature of efforts during professional football matches and compared two analytical models: one using a fixed metabolic power threshold (Pmet20) and another based on the relationship between oxygen consumption and metabolic power (VO2–Pmet). Data were collected from 24 First Division players in Cyprus across 50 matches during the 2022–2023 season using GPS technology (WIMU Pro System). High and low metabolic load efforts were analyzed. Results showed significant positional differences in both the duration and intensity of high metabolic load efforts and low metabolic load efforts. Compared to the Pmet20 model, the VO2–Pmet method identified approximately twice longer high metabolic load effort durations (≈4.1 vs. 2.1 s) and about 70–150% more detected efforts across positions, together with shorter recovery intervals. A notable decline in low metabolic load effort intensity between halves was linked to reduced performance. These findings highlight the dynamic interplay between aerobic and anaerobic systems in football and emphasize the need for position-specific training. Practical applications include designing training programs that reflect the unique intermittent demands of each position, focusing on both high-intensity efforts and recovery. This study provides a robust framework for understanding the football’s intermittent nature and offers actionable strategies to enhance player performance through tailored conditioning.
