The aim of this review was to consolidate and synthesise rugby union (RU) and rugby league (RL) studies on tackle and RU studies on ruck technique for rugby stakeholders. Forty-nine studies were identified (20 in RL and 29 in RU). RL studies primarily focussed on identifying factors that impact tackling ability. Leaner, fitter players, with greater lower body strength, tended to have more proficient tackle technique. Experience and level of play were positively associated with tackling ability. These findings highlight the importance of developing tackle technique and physical qualities to allow players to progress to higher levels. Research in RU mostly focussed on identifying tackle and ruck techniques associated with performance measures and injury outcomes. Eleven tackle techniques and five ball-carrier techniques were associated with both performance measures and injury outcomes. These findings support national injury prevention programmes that advocate that safe contact technique is also effective technique. (152 words)
