Abstract
The effect of variations in joint kinetics on step characteristics and velocity is not yet
known. To investigate contributions from the ankle, knee and hip to maximum velocity
sprint running, data were collected from four well-trained male sprinters performing
maximum effort 60 m sprints. High-speed video (200 Hz) and ground reaction force (1000
Hz) data were collected at the 45 m mark. Horizontal velocity and joint kinetics, via
inverse dynamics, were calculated for two trials in each athlete. The magnitude of
positive work performed by the ankle joint during the propulsive phase of stance was
closely linked to the velocity of the step, and thought to be the result of a coordinated leg
action during the support phase. The study revealed the potential for athlete-specific
biomechanical analyses to aid the technical work of athletes and their coaches.
