['To assess post-exercise recovery of human calf muscles using dynamic diffusion tensor imaging (dDTI).', 'DTI data (6 directions, b\xa0=\xa00 and 400\xa0s/mm', 'Active muscles (ATIB, EDL, PER) showed significantly elevated initial MD post-exercise, while predicted inactive muscles (SOL, LG) did not (p\xa0<\xa00.0001). The EDL showed a greater initial increase in MD (1.90\xa0×\xa010'] Does dynamic DTI ( dDTI ) show differing temporal activation patterns in post-exercise skeletal muscles?
