TEDx Talks - Athletes fear concussions—why don’t they report them? | Ben Jones | TEDxLeeds Beckett University
The speaker, Ben Jones, highlights the concern among rugby players about the long-term effects of concussions, with 60% of elite players worried about these implications. He explains that concussions are traumatic brain injuries resulting from impacts to the head, neck, or body. Research shows that in men's rugby league, there is one concussion every two games, with rates increasing over the years due to better diagnosis and awareness. Despite this, many players do not report concussions due to varying perceptions of risk.
Jones introduces the use of instrumented mouthguards to measure head impacts accurately. These devices help track head acceleration events, which are linked to long-term brain health risks. The data collected has led to changes in rugby rules, such as lowering tackle heights to reduce head injuries. These measures have successfully decreased concussion rates, particularly in women's rugby. The video emphasizes the need for ongoing research and collaboration to balance safety and performance in sports.
Key Points:
- 60% of elite rugby players are concerned about long-term concussion effects.
- Concussions are traumatic brain injuries from impacts to the head, neck, or body.
- Instrumented mouthguards accurately measure head impacts, aiding in concussion prevention.
- Rule changes, like lowering tackle heights, have reduced concussion rates in rugby.
- Ongoing research and technology are crucial for balancing safety and performance in sports.

1. 🎓 Introduction & Speaker Background
- 60% of elite rugby league players are concerned about the long-term implications of concussions.
- Sports offer significant benefits but come with inherent risks, prompting a need to balance these in a risk-averse society.
- The speaker's expertise in sports science and concussion management underscores the importance of understanding these risks.
- Emphasis on the importance of informed decision-making in sports participation to mitigate potential health risks.
- The speaker has a background in both academic research and practical application in sports environments, enhancing the credibility of the insights shared.
2. 🤕 Understanding Concussions in Sports
- Ben Jones, a professor at the Cara School of Sports, leads research on reducing sports risks while optimizing performance, particularly in rugby.
- Jones has published nearly 300 publications, most of which focus on rugby, indicating a strong research background in this sport.
- The talk will cover three main areas: understanding concussions and their risks, knowledge about head impacts, and the impact of research in this field.
- Jones aims to provide insights on how to reduce the incidence of concussions through data-driven strategies.
- The research emphasizes practical applications to improve safety in rugby based on extensive data analysis.
3. 📊 Concussion Rates, Player Concerns & Reporting Challenges
- A sport-related concussion is a traumatic brain injury from a direct blow to the head, neck, or body.
- In men's Super League Rugby in England, the average concussion rate since 2016 is one concussion every two games, or 15 per 1,000 playing hours.
- This rate is comparable to men's Rugby Union and slightly higher than women's rugby league and Rugby Union.
- Concussion rates in rugby league have increased from 2 per 1,000 hours in 2013 to 16 per 1,000 hours recently, showing a doubling and plateauing trend.
- The rise in reported concussion rates is due to improved identification, recognition, and diagnosis, rather than an actual increase in occurrences.
- These trends highlight the need for ongoing player safety measures and updated game regulations to mitigate long-term health risks.
4. 🦈 Risk Perception & Technological Advances
- 60% of elite players and 40% of community players are concerned about the long-term implications of concussions.
- 50% of parents of community players are also concerned about these long-term implications.
- 20% of elite players and 40% of community players do not report concussions, possibly due to their perception of risk.
- Concussion statistics in rugby: 1 concussion per 2 games, 1 per 4 games for a team, 1 per 68 player matches, 1 per 600 tackle events, and 1 per 2,000 player-level tackle events.
- Concussions are a traumatic brain injury, and efforts should focus on reducing their occurrence.
- Technological advances in rugby, such as sensor technology in headgear, are being developed to better detect and prevent concussions.
- Educational programs aimed at improving understanding of concussion risks and prevention are being implemented to address these concerns.
5. 🏉 Progress, Prevention & Future Directions in Sports Safety
- Recent research indicates a higher number of head impacts or head acceleration events across an athlete's career correlates to increased risk of long-term brain health issues.
- New technology in the form of instrumented mouth guards allows precise measurement of head impacts, providing valuable data for prevention strategies.
- Validation of instrumented mouth guards has led to their adoption in sports such as World Rugby and Rugby Football League, mandating their use for elite players, enhancing safety protocols.
- Data from men's Rugby Union matches shows that 50% of tackles or carries result in head acceleration events above 10g, while 15% exceed 25g, highlighting the importance of targeted prevention strategies.
- Lower instances of head acceleration events are noted in women's rugby and youth groups, suggesting variability in risk across different demographics.
- Reducing the legal height of tackles in rugby has demonstrated decreases in head acceleration events and concussion risks, prompting rule changes in the Rugby Football League and Rugby Union.
- Women's Super League has achieved a 50% reduction in head-on-head collisions by modifying tackle techniques, resulting in a decrease of concussions from 12 to 5 per thousand hours.
- In 2024, the Rugby Football League implemented 44 game changes, including tackle height adjustments and mandated mouth guards, based on research findings.
- Balancing performance and welfare in sports safety is crucial, as some data suggest a trade-off between competitive success and lower injury rates.
- Continued research and technological advances are essential to evolving sports safety protocols and reducing concussion risks.
