Variable thin filament lengths may increase internal resistance during cardiac shortening; leaves open relevance to human sarcomere mechanics.
The variation in thin filament lengths in cardiac muscle suggests that double overlap of thin filaments exists over a wide range of sarcomere lengths, contributing to internal resistance during shortening.
Robinson et al. (1979) studied this question.
