Provides mechanistic insight into myofibrillar supercontraction; leaves open relevance to cardiac sarcomere function in vivo.
Postmortem shortening in bovine muscle follows the sliding filament model, and trypsin treatment reverses supercontraction banding patterns by degrading Z lines.
Stromer et al. (1967) studied this question.
