Sex-based differences in the external loads imposed during an official ultimate-frisbee competition: monitoring of ultimate-frisbee demands

Introduction: The increase in the number of participants of Ultimate Frisbee suggest the necessity to improve the knowledge about this sport and its demands. Thus, the aim of this study was to quantify and compare the external loads imposed upon players during official Ultimate Frisbee matches according to sex. Material and methods: Twelve male and female players participated in four official Ultimate Frisbee matches. Players were divided according to sex (8 males and 4 females). Results: The average duration of matches was 62.3 ± 13.8 min, during which the players were active for 34.9 ± 11.4 min. External loads (i.e., total distance covered, distance covered at different speeds, accelerations and decelerations) encountered by Ultimate Frisbee players were compared between sexes (males vs females). Male players registered greater external loads (p < 0.05 large-moderate), especially performing high-intensity actions (distance at high intensity, distance at very-high speeds, and medium-high accelerations and decelerations) than female players. Conclusions: Coaching and performance staff should consider the sex of each player when developing training programmes and tactical strategies to optimise player performance during Ultimate Frisbee matches.
