A groundbreaking study reveals that lowering the legal tackle height in women’s community rugby has significantly reduced head contacts between players. Conducted by researchers at the University of Edinburgh in collaboration with Scottish Rugby and World Rugby, the study analyzed over 11,000 tackles across two seasons, showing a 64% drop in head and neck contacts, a major cause of concussions. The findings, published in BMJ Open Sport and Exercise Medicine, highlight the potential of this rule change to improve player safety globally.
The study compared tackle data from the 2022/23 season (before the rule change) and the 2023/24 season (after the change). Key results include:
- A 21% decrease in upright tackles and a 34% increase in tacklers bending at the waist, the recommended technique to minimize high-risk contacts.
- A 17% reduction in head-to-head and a 35% drop in head-to-shoulder contacts for tacklers.
- No rise in dangerous contacts with the ball carrier’s knees or hips, addressing prior safety concerns.
While penalties for high tackles increased, overall injury and concussion rates remained stable, though researchers noted the low number of reported injuries may have limited these findings.
Dr. Debbie Palmer, co-author of the study, emphasized, “Reductions in head proximity and contact are likely beneficial for preventing concussions. Robust injury data collection will help solidify these conclusions.”
The study underscores the success of the tackle height law in altering player behavior and reducing head contacts. As similar trials expand globally, continued research, including an upcoming youth rugby study, will further assess the rule’s impact on injury prevention. Scottish Rugby reaffirmed its commitment to prioritizing player welfare as the sport evolves.
