Abstract des Autors
Objectives: To establish the position and duration-specific running demands of Australian Football (AF) competition for the prescription and monitoring of specific training drills. Design: An observational time-motion analysis was performed on 40 professional AF players during 30 games throughout the 2014–15 competitive seasons. Methods: Player movements were collected and peak values were calculated for moving averages of between 1–10 min in duration for relative distance (m min−1), high-speed relative distance (HS m min−1), average acceleration/deceleration (m s2) and metabolic power (Pmet). A mixed-model analysis was used to detect positional differences, and differences were described using a magnitude-based network. Results: Relative distance was likely greater for midfielders (MID), and mobile forwards (MF) compared to tall backs (TB) across all moving average durations assessed, with MF peaking at 223 ± 35 m min−1 for a 1-min window. High-speed relative distance was at least likely to be greater for MF compared to all other positions, across all moving average durations (ES = 0.27–0.94). Acceleration/deceleration demands were similar across positions. Conclusions: The present study demonstrated that the peak running intensities of AF are well above previously reported peak intensities when considering the distance-based running requirements of match-play. Whilst the acceleration-based metric was unable to detect large differences between positions, it is important to note their contribution to the overall competition demands. This study presents a useful framework for the prescription and monitoring of drills specific to AF competition requirements.
