2-D Running Analysis Write-up

When measured from multiple angles, 2-dimesional video can give great insight into running mechanics, allowing for a frame-by-frame biomechanical analysis. Variables which dictate running patterns (such as overstride, thigh extension, footstrike, and heel whip) can be reliably measured and quantified. Once gathered, the correlation between these components can be calculated and used to make predictions about the effect of each.
