In the March 2014 issue of Medicine & Science in Sports & Exercise?, researchers investigated the effect of exercise on the reaction times of collegiate athletes using a clinically validated tool to measure reaction time (RTclin) (2). The purpose of the study was to determine the effect of exercise on RTclin in order to understand this tool’s utility as a sideline concussion assessment tool. Pilot work has demonstrated already the reliability and validity of RTclin as well as its sensitivity to concussion in the days following an injury. The authors hypothesized that RTclin would decrease with exercise of moderate intensity and increase with more intense levels of exercise.
