Stretch of active whole muscle causes a sudden yielding of the sarcomeres when the actin and myosin filaments are displaced by 10‐12 nm from their isometric position. This behaviour is not normally seen during stretch of singly‐dissected fibres, but it can be induced by introducing series compliance into the system.
