The parameters are: force in isometric conditions, T₀, and during steady lengthening, T_v; stiffness in isometric conditions, e₀, and during steady lengthening, e_v; hs strain in isometric conditions, Y₀, and during steady lengthening, Y_v; average strain per cross-bridge in isometric conditions, F₀/ɛ₀, and during steady lengthening, T_v/β_vɛ₀; stiffness of the cross-bridges in isometric conditions, βɛ₀, and during steady lengthening, β_vɛ₀.
