Age‐related differences in strain rate tensor of the medial gastrocnemius muscle during passive plantarflexion and active isometric contraction using velocity encoded MR imaging: Potential index of lateral force transmission

The strain rate (SR) tensor measures the principal directions and magnitude of the instantaneous deformation; this study aims to track age‐related changes in the 2D SR tensor in the medial gastrocnemius during passive joint rotation and active isometric contraction.
