The study investigated the influence of vest loading on relative GRF’s during maximum velocity sprinting, and determined the relationship between flight times and relative vertical GRF’s. As a vertical vector-training stimulus, vest loading decreased flight times and vertical GRFs. Vertical loading does not seem to produce desirable effects on sprinting performance or GRFs.
