WebQuestion. Hill's equation gives a relation between muscle contraction rates νν and muscle tension TT. (T+α) (ν+β)= (T0+α)β (T+α) (ν+β)= (T0+α)β. for positive parameters αα and ββ and resting tension T0T0. Rewrite the equation so … WebJun 1, 2006 · Because the excess heat of shortening must be zero when there is no shortening (during an isometric contraction), c must equal b P 0, where P 0 is the force generated by an isometric contraction. Incorporating this fact and rearranging the equations yields the famous Hill equation, presented as Eqs. 1 and 2 in his paper: (6)

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.
