Lowering the legal tackle height in women’s rugby is proving effective in reducing head contacts between players, a new study suggests. Changes to the tackle height law in women’s community rugby in Scotland is linked to reductions in head-to-head and head-to shoulder contacts, the study found. The researchers used video analysis to study the impact of the lowered tackle height law which World Rugby, the sport’s governing body, introduced for community rugby in an attempt to improve safety for players.
