  • Re: Normalised Force-Length and Force-Velocity data for humanlower-extremity muscles

    Thank you all for the prompt replies and the directions which are very helpful. Below I post a summary of responses to my message:

    1) A very good source is Delp's lower extremity model:
    http://isbweb.org/data/delp/index.html, click on "muscle file".

    Normalized force-length and force-velocity relationships from this file
    are attached below.

    Force is normalized to maximum force, length to optimal fiber length,
    and velocity to maximal shortening velocity.

    2) We are collecting torque - position and torque-velocity data at the
    knee, but it is not for individual muscles, but rather net joint
    torque... Laura

    3) You can look at the Prof. Delp's dissertation in 1990:
    Delp, S.L. (1990) Surgery simulation: a computer graphics system to analyze and design musculoskeletal reconstructions of the lower limb. Dissertation, Stanford University.


    Here is his lab's website: http://nmbl.stanford.edu/


    Good luck!
