Redesigned ball could reduce heading impact - scientists
Summary
Scientists have found that heading a football causes a pressure wave that transfers energy to the brain, which varies by the type of ball and playing conditions. The research suggests redesigning footballs could reduce this impact and help prevent brain injuries linked to heading.Key Facts
- Researchers at Loughborough University studied how different footballs transfer energy to the brain when headed.
- They used a special pressure sensor inside a model head to measure the impact at match speeds.
- The pressure wave energy transfer to the brain can be up to 55 times greater with some balls compared to others.
- The design, speed, and wet or dry condition of the ball affect the amount of energy transferred.
- Leather footballs from past decades did not always produce higher energy transfer than modern balls.
- This research is linked to concerns about brain diseases in players caused by repeated heading.
- The Football Association has started limiting heading in youth football to reduce risks.
- Scientists hope new ball designs can lower the energy passing into players’ brains to help protect their health.
