Abstract

This study assessed select kinetics and kinematics of each of the first three steps of the acceleration phase of sprinting using three different acceleration ladders. Subjects (N=15) performed sprints using acceleration ladders with short, medium, and long rung spacing, over two large force platforms. Multi-factorial repeated measure ANOVAs were used to assess horizontal and vertical ground reaction force (GRF), the ratio of horizontal to vertical GRF, the duration of vertical GRF, time between steps, distance between steps, and velocity between steps and across all steps. Main effects were significant (p ≤ 0.05) for all variables except time. Post-hoc analysis identified a variety of differences in the dependent variables in the analysis of steps, test condition and their interaction (p ≤ 0.05). Results show that greater velocity is attained with ladders that have longer step distances.
