Muscle-Tendon Junction (MTJ) displacement, MTJ angle, and Real-time tissue elastgraphy (RTE) after each stretching condition. Significant changes in MTJ angle (0°, 10°, 20°) and RTE (0°, 10°, 20°) were found after Static Stretching (SS) stretching compared with and cyclic stretching (CS). There were no significant differences in MTJ displacement between SS and CS.†  Indicates a significant difference in each condition (p < 0.05).† †  Indicates a significant difference after SS compared with CS (p < 0.01).
