Table 2.
Average (±s.d.) recommended (Rec) prosthetic stiffness values (kN m−1) for a 70 kg athlete across running speeds and prosthetic stiffness values (kN m−1) from ±1 stiffness categories across speeds. We averaged prosthetic stiffness values at each category for each model, and then averaged stiffness values across models for the respective recommended category (i.e. Rec, or ±1). Prosthetic stiffness was related to running speed (p < 0.001).
