Relationship between muscle damage variables (maximal voluntary isometric contraction (MVIC) force, circumference (CIR), relaxed elbow angle (RANG) and extended elbow angle (EANG)) and muscle hardness assessed by push-in meter (PM) and strain elastography (SE). A significant (p < 0.001) correlation was evident between MVIC and PM (r = − 0.565, A), MVIC and SE (r = − 0.516, E), CIR and PM (r = 0.692, B), CIR and SE (r = 0.518, F), RANG and PM (r = − 0.772, C), RANG and SE (r = − 0.745, G), EANG and PM (r = − 0.548, D) and EANG and SE (r = − 0.575, H).
