Dear All,

I don't have any experience in muscle mechanics and I may well be asking a
completely daft question, but here goes...

I am trying to estimate the additional force in an active muscle-tendon unit
(MTU) generated by a load applied normal to its axis - imagine the string of
a bow being drawn. I have some data for the force in the MTU during the
particular activity I am considering, presented as a force-length
relationship. The slope of this relationship is near to linear, which
suggests that I might consider the active MTU as an elastic string. If I
were to assume that this was true, I could calculate the additional force in
the MTU just from the extension caused by the normal force. Does anyone have
any comments on whether this is a sensible approach? Or am I completely off
track?

Cheers

Andrew
