Description

Purpose: The purpose of this study was to draft of effective training methods of transversus abdominis muscle time is necessary to acquisition, tending to be difficult as for the coaching. <br>Methods: The subjects were healthy males who were examined in a sitting position with a stably maintained physiological lumber flexure under the following six conditions: grounding of both feet (stable or unstable seating face and plantar face), extended opposite knee joint (stable or unstable seating face and plantar face), extended opposite knee joint with a heavy burden (a bob of 2kg), and supine position. The thicknesses of the transversus abdominis, internal abdominal oblique muscle, and external abdominal oblique muscle were measured by ultrasound imaging under each condition and differences in these data were evaluated. <br>Results: Compared with measurements in the supine and seated positions with both feet in contact with the ground, the thickness of the transversus abdominis was significantly larger (p < 0.05) under the other four conditions. The thickness of the internal abdominal oblique muscle was significantly larger with an extended opposite knee joint (unstable seating face and plantar face) and an extended opposite knee joint with a heavy burden (p < 0.05). <br>Conclusion: These results suggest that conditions of an extended opposite knee joint (stable seating face and plantar face) in the sitting position with a stably maintained physiological lumber flexure and a sitting position with both feet in contact with the ground are effective for training since they promote selective constriction of the transversus abdominis.
