Abstract
BACKGROUND: The tackle event in rugby is a technical and physical contest between opposing players. A player's ability to tolerate and contest during a tackle is a prerequisite for safe participation and success in rugby. Little is known about the relationship between tackle training and tackling in matches in rugby union. Therefore, we investigated the relationships between players' training attitudes and behaviour and their match attitudes and behaviour for tackling in rugby union.Entities:
