Force-velocity and force-length relations

The faster muscle shortens, the less force it produces; force also depends on length; power peaks in between.

A few cards from the deck

  • Force-velocity relation: what is it?

    Show the answer

    In concentric work, maximal force falls as shortening speed rises.

    It is Hill's curve, a hyperbola.

  • Why is a very heavy load lifted slowly?

    • Great force is only available at low velocity
    • To save ATP
    • Because type I fibres work
    • Only out of caution
    Show the answer

    Great force is only available at low velocity

    That is the force-velocity relation.

  • Maximal isometric force: what is it?

    Show the answer

    The force at zero velocity, the curve's highest point.
