Body armor designs that limit the range-of-motion required for vital law enforcement tasks, such as shooting may be dangerous. Therefore, a posture based biomechanical analysis was performed to determine if upper body joint angles can be used to assess the effects of armor designs on assumed shooting. Participants (n=8) completed a battery of simulated duty tasks for three armor configurations (no armor, concealable, and tactical armor) while motion capture was used to compute included joint angles of the upper extremity and neck. In general, joint angles were impacted by armor configuration, and law enforcement experience (measured in years) significantly impacted their shooting posture. It was also found that the types of tasks performed interacted with shooting stance. This research is a first step at developing a method to analyze body armor designs and their impact on wearers, so that mobility may not need to be sacrificed for additional protective coverage.
