Improvements in helmet design and technology that have reduced head motion during American football collisions. Despite these improvements, those that play the sport still receive head injuries. Our purpose was to determine which of two commonly used helmet types (Vicis and Riddell) were associated with biomechanics less likely to lead to head injury. Using a force plate (insert make and model) connected to a motion capture system, we conducted linear drop tests from four different heights (5 ft, 6.5 ft, 8.5 ft, and 10 ft) for both helmets. A 10 lbs dumbbell was strapped inside the helmets for each trial to mimic the weight of a human head. Three trials were conducted at each height for each helmet type. Peak force, peak instantaneous loading, and peak linear accelerations for each helmet type were calculated. Helmet types were compared for each dependent variable using independent t-tests (alpha < 0.05). The Vicis Zero1 helmet had lower helmet acceleration than the Riddell helmet, and this was independent of drop height. Therefore, based on measured impact biomechanics, the Vicis helmet may reduce head trauma risk and reduce the amount of collision related head injuries as compared to the Riddell helmet.
