Tracking of foot movement during sprinting in studded footwear

Mechanical tests and finite element simulations are often used to assess the traction between a studded outsole and the surface. Appropriate boundary conditions are required in these experiments in order to replicate realistic loading scenarios. The result of using different boundary conditions has been well researched (Nigg 1990, Kuhlman et al. 2009. Kirk et al. (2007) used a high-speed video camera to investigate kinematic boundary conditions in 2D during the acceleration phase in sprinting. The study was limited as the angle of the shoe could only be calculated in one plane. Analysis of high-speed footage in 3D is possible using a two camera system, as per Choppin et al. (2007) who determined the orientation of a tennis racquet during play in three planes.
