Storage and release of mechanical energy by active muscle: a non-elastic mechanism…
ABSTRACT. In frog muscle fibres, tetanically stimulated at a sarcomere length of about 2 pm, stretched at a velocity of 1 length s-1 and released against a force equal to the maximum isometric, P0, a phase of rapid isotonic shortening takes place after release. As the amplitude of the stretch is increased from 1 · 5 to 9 % of the initial length: (1) the amount …
