Purpose Exposure to head acceleration events in rugby can lead to both physical and mental health problems, even without a diagnosed traumatic brain injury. This study aimed to explore relationships between gameplay head impact conditions and head acceleration metrics experienced by rugby players. Methods Using head impact kinematic data from two high school rugby union teams in New Zealand (one male and one female), linear mi...
Purpose This study evaluates the impact-attenuation of two softshell headgear models, GameBreaker-Pro and GameBreaker-Prototype, in controlled drop tests. These models were selected to assess the effect of thickness, given the 12 mm thickness constraint specified under World Rugby Law 4 Trial regulations for which limited justification exists. Methods Drop tests were conducted using a Hybrid III headform and neck, from heights...

In contact sports such as rugby, players are at risk of sustaining traumatic brain injuries (TBI) due to high-intensity head impacts that generate high linear and rotational accelerations of the head. Previous studies have established a clear link between high-intensity head impacts and brain strains that result in concussions. This study presents a novel approach to investigating the effect of a range of laboratory controlled...

World Rugby employs a specific drop test method to evaluate headgear performance, but almost all researchers use a different variation of this method. The aim of this study was, therefore, to quantify the differences between variations of the drop testing method using a Hybrid III headform and neck in the following impact setups: (1) headform only, with a flat steel impact surface, approximating the World Rugby method, (2 and...

Rugby union is a popular sport played across the world. The physical contact inherent in the game means that players are at increased risk of concussive injury. In 2019, World Rugby created a new category of permitted headgear under Law 4 as a medical device. This established a pathway for headgear designed to reduce peak accelerations to be worn in matches. Investigations of the potential of soft-shelled protective headgear t...
