Zusammenfassung

Die Sarkomer-Bewegung während isometrischer Muskelkontraktion wurde mit Hilfe der Lichtdiffraktion untersucht. Die Anfangsgeschwindigkeit der relativen Bewegungen des Actins und Myosins betrug bei 7°C etwa 2 μ/sec−1. Nach Reiz-Ende verkürzen sich die Fasern noch etwas und zwar in der gleichen Art nach Tetanus wie nach Einzelzuckung.
