Figure 4From: Effect of exercise-induced muscle damage on muscle hardness evaluated by ultrasound real-time tissue elastographyTime course of changes in ankle dorsiflexion ROM and strain ratio of the MG before and after exercise. Values are represented as mean ± SD. *P < 0.01: significantly decreased ankle dorsiflexion ROM compared with pre-exercise value. ✝P < 0.01: significantly lower strain ratio compared with pre-exercise value in the MG.Back to article page
