Mechano-chemical model describing the force-velocity relationship in muscle

Abstract

Abstract:Performance of the muscle is examined employing the self-excited oscillation analysis, which is useful to express the force-velocity relationship in muscle. What the present formula suggests is that when a muscle is activated, mechanical myoplasmic resistance initially drops, and then part of the contractile elements build up a tensile stress equal to tensile strain (load, p) while the rest part of these elements draw the load and shorten the muscle. The new formula is mathematically identical with Hill's equation, but utilizes only a single constant (3), which implies an important intrinsic property of muscle and is deserving of further investigation.
