Head Injury Risk in Combat Sports
The goal of this study was to quantify head injury risk associated with different striking locations for athletes in combat sports. A crash test dummy, instrumented with sensors, was impacted in different locations of the head by a pneumatic ram. Injury risks were assessed and compared to human injury thresholds from literature.
Helmet Effectiveness in Falls from a Horse
The use of equestrian helmets in competitions is typically required, but many recreational riders still have the option to wear a helmet when riding a horse. In this study, linear and rotational kinematic data obtained from unhelmeted and helmeted conditions were used to evaluate the effectiveness of current equestrian helmets in preventing head injuries when falling from a horse.
Effect of Head Mass on Youth Football Player Concussion Risk
Increases in technology used in football helmets has more than doubled their weight in the last 20 years; yet the effect of this added weight on head stability in youth players is still unknown. This study sought to correlate the effect of increased helmet mass with concussion risk in youth football players by impacting a helmeted child crash test dummy at speeds and locations commonly seen during play.
Factors Effecting Youth Football Helmet Fit and Impact Performance
Modern football helmets have complex padding designs and advanced multi-component outer shells; yet, the fit and retention systems (e.g. chinstraps) used to hold helmets on an athlete’s head have largely remained unchanged for the last 50 years. This work investigated relative motion between the head and helmet during football hits and examined factors that affect the way a helmet fits. Additionally, this study investigated how fit alters a helmet’s ability to mitigate impact forces.
