Hill's equation of muscle contraction
Did you know?
This is a popular state equation applicable to skeletal muscle that has been stimulated to show Tetanic contraction. It relates tension to velocity with regard to the internal thermodynamics. The equation is $${\displaystyle \left(v+b\right)(F+a)=b(F_{0}+a),\qquad (1)}$$ where … See more In biomechanics, Hill's muscle model refers to either Hill's equations for tetanized muscle contraction or to the 3-element model. They were derived by the famous physiologist Archibald Vivian Hill. See more The three-element Hill muscle model is a representation of the muscle mechanical response. The model is constituted by a contractile element (CE) and two non-linear spring elements, one in series (SE) and another in parallel (PE). The active force of the contractile … See more • Muscle contraction See more Web“fundamental equation of muscle contraction,” also known as Hill’s equation, (L+m)(V+n) = k, where L is the load that the muscle is lifting, V is the velocity of contraction of the muscle, and m, n, and k are constants.
