While sports facilities and leagues are still gauging how and when to reopen in the wake of the coronavirus, now is the best time to think about concussion prevention: before young people get back on the playing field.

The benefits of , and yet, every day young people put themselves at risk of concussion through participation in sports. The highest concussion incidence rates among youth in Canada are seen in .

We expect  every year for a sport-related concussion. Forty per cent of these .

These symptoms may include . Long-term consequences of concussion in youth may also include reduced levels of physical activity, overweight or obesity, psychosocial consequences and significant health-care costs.

As chair of the , I lead a research program that aims to reduce the burden of youth concussion in Canada. The best way to do that, and to keep kids active in the sports they love, is by moving towards prevention. Providing a safe environment for youth to participate in sport is critical to ensure lifelong participation in sport and recreation. As such, a key public health priority should be concussion prevention in youth sport to promote an active lifestyle in all Canadian youth.

How can we prevent concussion in youth sport?

 that rule changes, training strategies, equipment recommendations and legislation of evidence-informed management protocols can all help to prevent concussion and the recurrence of concussion in youth sport.

 in reducing the risk of concussion in youth sport. In 2010, we demonstrated a  in 11- and 12-year-old ice hockey players when body checking was allowed in games at all levels of play, compared to Québec where body checking was not allowed.

This study, among others, informed a 2013 Hockey Canada national policy change delaying body checking until age 13. This led to a  in young players, and keeping more players in the game.

This research further informed local and provincial policy change in non-elite levels of play (70 per cent of players by division of play) in older age groups (ages 13-17). , with a 54 per cent reduction in all injuries and estimated prevention of 4,000 injuries in 13- and 14-year-old players annually in Canada.

If body checking continues to be disallowed in games in 11- and 12-year-old leagues and non-elite levels in 13- to 17-year-old leagues, the public health impact would be the prevention of 10,000 concussions annually.

Prevention should be our priority, but not everyone involved in the game sees it this way. Some parents believe that delaying body checking to age 13 may reduce concussion risk but that this policy will also reduce their child’s opportunities to play at elite and professional levels.

. Possibly 70 of these kids may have an opportunity to compete in the National Hockey League () and perhaps 7,000 may continue to play in an adult recreational league.

One might argue that the other 62,930 young players should be our public health priority. Our goal should be to keep these kids in the game for lifelong participation in sport and recreation.

Another rule change targeting concussion prevention in youth sport includes .

Other evidence-informed prevention strategies include sport-specific  (including aerobic, balance, strength, agility) that have been shown to reduce the risk of all injury, including concussion, by more than 35 per cent across multiple team sports including ,Ìý,Ìý and in .

We should not underestimate the potential of preventive equipment including  with recent evidence demonstrating that wearing a mouth guard (off the shelf or custom fit) reduced odds of concussion in youth ice hockey players by more than 60 per cent.  criteria have also been developed and evaluated in youth ice hockey and tackle football, suggesting the potential for a protective effect and reduced concussion severity with optimal helmet fit.

Can concussions lead to catastrophic outcomes?

Catastrophic outcomes following concussion in youth sport are rare, however we should work to ensure that not one more child dies following concussion. Rowan Stringer was a 17-year-old high school rugby player who suffered multiple concussions in one week in 2013 and died as a result of her injuries. Stringer’s lasting legacy is  that was subsequently introduced into Ontario legislation following her death.

Rowan’s Law is a wake-up call to sport associations, sport facilities and schools to implement concussion protocols mandating the removal from play of any youth athlete with a suspected concussion. Rowan’s Law also makes concussion education mandatory for certain individuals involved with youth sport. Additionally, it informs appropriate protocols for concussion follow-up including assessment by a physician and adherence to evidence-informed return-to-sport and return-to-school guidelines.

Canadian researchers raising the bar

Through a research program funded by the NFL’s Scientific Advisory Board, our team at the Sport Injury Prevention Research Centre is leading a pan-Canadian multidisciplinary research group focused on the prevention, detection, diagnosis, prognosis and management of sport-related concussion in youth. SHRed Concussions (Surveillance in High School to Reduce Concussions and their Consequences in Youth Sport) is the first study of its kind in Canada. It aims to recruit 6,000 high school athletes (ages 13-18) in 60 schools (in British Columbia, Alberta, Manitoba, Ontario and Québec), with followup over three years.

The goal of SHRed Concussions is to raise the bar in youth sport-related concussion research and to inform a significant public health impact in the reduction of sport-related concussions and their consequences in youth across multiple sports including tackle football, rugby, ice hockey, lacrosse, wrestling, ringette, soccer, basketball, volleyball and cheerleading.

Why are we so afraid of change?

Canada’s youth are our biggest and most important natural resource.  reminds us every day that there is a lot to do to keep sports safe and prevent sport-related concussions in youth. We must ensure legislation is in place for concussion prevention and management protocols to minimize the risk of catastrophic outcomes and reduce the burden of concussions in youth sport.

The benefits of changing the rules of the game, safety equipment legislation and evidence-informed training strategies have been significant in reducing the burden of concussion in youth sport. Evaluation of concussion prevention strategies is ongoing across multiple youth sports. Our priority must be to keep all youth participating in sports and also physically active for life.
