FIGURE 4.

Mean (±standard error) normalised predicted ankle muscle torques from static optimisation in the Generic elderly (a), Generic elderly optimised (b), Generic young (c), Generic young optimised (d) and Subject‐specific (e) models against mean experimentally derived normalised ankle muscle torques measured from an isokinetic dynamometer. Root‐mean‐squared errors expressed in Nm/kg and as % of maximum isokinetic torque show that on average, the subject‐specific models predicted maximal muscle torques to the greatest degree of accuracy through both ankle plantarflexion and dorsiflexion relative to all other models
