Implication

Challenges fixed filament length at short sarcomeres; leaves open relevance to human cardiac mechanics.

Population

Glycerinated skeletal and cardiac muscle of a benthic fish, Coryphaenoides species

Intervention

ATP-induced contraction

Comparator

Resting muscle

Outcome

Myofibrillar structure (sarcomere length, thick and thin filament length, interdigitation)surrogate

Contraction of Coryphaenoides muscle to shorter sarcomere lengths is accompanied by shortening of thick filaments, suggesting a structural change within the thick filament core.

Limitations

Effects from heterogeneity of filament length cannot be excluded with certainty
