The association between age and endurance time for an isometric contraction in which the dorsiflexors supported a submaximal inertial load equivalent to 20% 1-RM load in young (open circles) and older adults (filled circles). The R2 of curvilinear power model was greater than that of the linear model, suggesting a non-linear relation between age and dorsiflexor fatigability in old adults.
