The Efficacy of Impact-Absorbing Materials during Collision with a Soccer Ball

The uniqueness of soccer is that the players are allowed to use their head to pass the ball to a teammate of even try to score goal. Studies have shown that heading in soccer might be dangerous to the brain and could lead to brain trauma. There are headgears available for soccer players to protect t...

The reduction in peak force was associated with longer impact duration between the soccer ball and the PU comb-gel.

A combination of PU gel and another stiffer material is suggested and the effectiveness of the composite will be the subject of future investigation.
