This study assessed a variety of kinetic, spatial, and temporal variables during the early acceleration phase of sprinting for both men and women (N = 20) during standing and sprinter position starts. Forces, step distance, time, and velocity measured from the first four steps of each start via force platforms were compared across start, step, and sex via ANCOVA while removing the effect of height or weight. Velocity increased from step 1 to steps 2 and 3; while overall velocity was lower for women and the standing start (p < 0.05). There were interactions of start * sex for horizontal force, ratio of horizontal to vertical force, overall velocity, and overall time (p < 0.05). Men’s performance tended to be more negatively affected when using the standing start than women’s performance.
