An explanation for residual increased tension in striated muscle after stretch during contraction

A recent review article in this journal (Noble, 1992) concluded that 'The effects of stretching actively contracting muscle remain perplexing and unexplained ... The puzzlement of Deleze (Deleze, 1961) is reiterated with little modification by myself, after reviewing the literature of the intervening 30 years!' This paper is intended to show that an explanation is available to account for all the features that puzzled Deleze, Noble and others, and that evidence to support it is growing.
