Outline of Final Research Achievements	In this study, we aimed to estimate the muscle activity by measuring the muscle hardness of deep layered trunk muscle using ultrasound elastography, and to develop a strengthening method of the muscle. We confirmed moderate to high reliability of the ultrasound elastography to quantify transversus abdominis hardness. In the transverse abdominis the muscle hardness was particularly high during bracing maneuver. However, no improvement of exercise performance was found after an intervention using bracing maneuver.
