1 The sarcomere length-tension relationship for the human extensor carpi radialis brevis (ECRB) and the biceps femoris, long head. The data for the ECRB were determined from intraoperative laser diffraction measurement of the sarcomere length, and the data from the biceps femoris were calculated on the basis of ultrasound measurements of the change in fascicle length with joint position.35 The dark line is the presumed length-tension relationship of human muscle, based on the known lengths of human thin and thick filaments.
