The aim of the study was to profile high intensity events (HIE) in international female team handball matches, with regards to playing positions. Methods: Twenty female national team handball players were equipped with inertial movement units (OptimEye S5, Catapult Sports, Australia) in 9 official international matches. Players were categorized in four different playing positions: backs, wings, pivots, and goalkeepers (GK). Player Load™, accelerations (Acc), changes of direction (CoD), decelerations (Dec), and the sum of the latter three, HIE, were extracted from data raw-files, using the manufacture's software. All Acc, Dec, CoD, and HIE >2.5 m·s -1 were included. Data were log-transformed and differences were standardized for interpretation of magnitudes and reported with effect size (ES) statistic. Results: Mean number of events was 0.7 ± 0.4 Acc·min -1 , 2.3 ± 0.9 Dec·min -1 , and 1.0 ± 0.4 CoD·min -1 . Substantial differences between playing positions, ranging from small to very large, were found in the three parameters. Backs showed a most likely greater frequency for HIE·min -1 (5.0 ± 1.1 HIE·min -1 ), than all other playing positions. Differences between playing positions was also apparent in Player Load·min -1 . Conclusion: The present study shows that HIE in international female team handball are position specific, and that the overall intensity is dependent on the positional role within a team. Specific HIE and intensity profiles from match play provide useful information for a better understanding of the overall game demands and for each playing position.
