Table 1.

Photos and characteristics of the five floor conditions tested in this study. Footfall deflection values were estimated from force-deflection tests under a simulated 1000 N footfall using a rigid foot-shaped indenter mounted within a materials testing system (Laing and Robinovitch, 2009).
