Jockeys’ head injuries and skull cap performance

Harrison, T. I.; Mills, N. J.; Turner, M. S.

The Jockey Club collected skull caps after jockeys suffered concussive head injury. 56% of the newer design of cap showed impact sites near the lower rim of the cap, indicating that it offers improved protection. The impact damage of the caps was described. For some caps, head linear accelerations were estimated to about 100 g. Videos showed that several jockeys somersaulted as they hit the track, and that there was significant head rotation. For the caps with minor liner damage it was not possible to decide if concussion was caused by linear or angular head acceleration.
