Fig. 3From: Neurochemical mechanism of muscular pain: Insight from the study on delayed onset muscle sorenessModified from Hayashi et al. [89]Muscular mechanical hyperalgesia after lengthening contractions in rats depends on stretch velocity (VEL) (a–e) and range of motion (ROM) (f–j), and muscle fiber damage such as necrotic fibers (k) and Evans Blue dye-positive fibers seldom observed (k–p).
