Implication

Underscores fastest-fiber dominance in unloaded shortening; extends force-velocity models in rat soleus but leaves open human translation.

Population

Soleus muscles from rats (n=10)

Intervention

Measurement of shortening velocity at zero load (Vmax) extrapolated from isotonic releases

Comparator

Unloaded shortening velocity (V0) determined by the slack test

Outcome

Comparison of Vmax and V0surrogate

In rat soleus muscles, V0 measures the unloaded shortening velocity of the fastest fibres, whereas Vmax reflects the force-velocity characteristics of all fibres.
