The objective of this study was to characterize the differences in sprinting created by verbal instruction of biomechanical factors. Ten college-aged males with no prior sprint training participated. Three variables, found to be correlated with decreasing the time to reach maximum speed in overground running, were chosen to be verbally instructed. Participants were randomly assigned into two groups: coached and not coached. Each group separately completed the same training procedure. Before and after the five-week training period, loadrate, impulse, and overall peaks of ground reaction forces were investigated for the acceleration phase of the sprint. While, average velocity, stride length, and frequency were measured during the maximum velocity phase. ANOVA results showed only the maximum propulsive force being greater in the coached group than in the not coached group (p<0.001). These results support the potential to improve sprint acceleration based on verbal coaching of biomechanical factors.
