Some Specific Predictions and Experiments on Single Myofibrillar Mechanics

  • Tatsuo Iwazumi
Part of the Advances in Experimental Medicine and Biology book series (AEMB, volume 37)


The length-tension relationship of myofibrils approximately 50 sarcomeres long from skinned single atrial cells was measured. All sarcomeres were observable throughout the experiments. The tension developed at submaximal Ca2+ concentrations consistently increased with the sarcomere length.
