“…Eight studies investigated the effects of MCT on muscle thickness during rest of TrA (26,27,30,43,44,49,50), IO (27,30,43), EO (27,30,43), rectus abdominis (RA) (30) and multi dus muscles (26,44,47,49,50). Six articles analyzed treatment-related changes in the "contraction ratio" of the TrA, IO, and EO muscles (28,29,45,48,51,52). Only one study also evaluated abdominal muscle timing using USI (46).…”
