Le déficit de la tension tétanique redéveloppée après un raccourcissement.

(eng) Tension (force per unit muscle cross-section) redeveloped after the shortening, Pd, is generally less than the tension Ps observed if the muscle is stimulated isometrically at Ls. The tension deficit, Q = Ps - Pd, depends on the speed and extent of the prior shortening. The hypothesis advanced earlier (MARÉCHAL & PLAGHKI, 1977) accounts for these phenomena. The new bridges formed by the fractions of filaments I which enter band A during the shortening are more or less inhibited at the very moment of their formation, as a function of the force which the I filaments have to sustain.
