Figure 1. Typical examples of ultrasound shear wave elastography measurements of the biceps femoris long head (BFlh) in concentric (CON) and eccentric (ECC) tasks. Measurements were performed before (PRE) and 30, 60, 90, and 120 s after each task (POST30, POST60, POST90, POST120, respectively). The colored region represents the shear modulus map with the scale below the images. Scale bar = 1cm.
