Questions applicability of hyperbolic force-velocity models near isometric loads; leaves open relevance to mammalian cardiac muscle.
The force-velocity relation in skinned frog muscle fibres is biphasic, with the altered shape at high loads likely related to the speed of shortening rather than the force level per se.
Lou et al. (1993) studied this question.
