Smart mouthguards and contact sport: the data ethics dilemma.

The use of smart mouthguards in contact sports like rugby aims to enhance player safety by providing real-time data on head impacts. These devices, equipped with sensors, measure collision force and frequency, potentially identifying concussions that might go unnoticed during gameplay. The idea is that such enhanced monitoring will enable teams, physicians and other stakeholders to better protect players from the effects of on-pitch injury through immediate detection of head trauma and the long-term provision of player data. While we welcome the move towards a better understanding of the potential harm that contact sports athletes may experience, introducing a new avenue through which information about player performance and health can be collected brings several areas of ethical concern absent from traditional mouthguards. In this paper, we consider four noteworthy areas: device and data efficacy, player choice, the inherent issues of such data's existence and the harmful consequences of this data's usage and exposure. We argue that failing to identify and address the risks associated with smart mouthguards' employment in the elite sporting sphere not only risks the mistreatment and misapplication of player data but may also jeopardise the acceptability of a novel health monitoring method that has the potential to prevent long-term debilitating diseases.
