The Performance Demands and Technical Determinants for Tackle and Ruck Success During the Pool and Knockout Stages of the Men's International World Rugby Sevens Series.

The purpose of this study was to compare tackle and ruck frequencies between pool and knockout matches during the Men's International World Rugby Sevens Series and also determine which technical determinants increase the likelihood of tackle success within each stage of the tournament. Video analysis of all matches during the 2018/2019 International Men's Rugby Sevens World Series was conducted (n = 449 matches). This equated to 21226 tackle contact events and 6345 rucks events.
