The present invention relates to a device for measuring the muscular strength of a muscle transversus abdominis. The device comprises: a pressure receiving unit (3) which is inserted between the waist bone of an object (P) to be measured and a measurement surface (M) when measuring the muscular strength of a muscle transversus abdominis in a pose made by making the back of the object (P) to be measured to be close contact with the measurement surface (M), thereby generating a pressure by being compressed by the pressure of the object (P) to be measured through the muscle transversus abdominis an air injection unit (5) which injects air into the pressure receiving unit (3) to measure the muscular strength of the muscle transversus abdominis of the object (P) to be measured a pressure measuring unit (7) which measures a pressure generated when the object (P) to be measured presses the pressure receiving unit (3) through the muscle transversus abdominis and a pressure displaying unit (9) which displays a pressure measured in the pressure measuring unit (7) to be checked. The present invention is able to increase convenience in measuring the muscular strength of a muscle transversus abdominis since the muscular strength of the muscle transversus abdominis is able to be simply measured through the pressure receiving unit.본 발명은 복횡근 근력 측정장치에 관한 것으로, 측정대상자(P)가 측정면(M)에 등을 밀착한 자세로 복횡근의 근력을 측정할 때, 상기 측정대상자(P)의 허리뼈와 상기 측정면(M) 사이에 끼워져, 복횡근을 통한 상기 측정대상자(P)의 압박에 의해 압축되어 압력을 발생시키는 수압부(3) 상기 측정대상자(P)에 대한 복횡근 근력 측정을 위해, 상기 수압부(3)에 공기를 주입하는 공기주입부(5) 상기 측정대상자(P)가 복횡근을 통해 상기 수압부(3)을 압박한 때 발생한 압력을 측정하는 압력측정부(7) 및 상기 압력측정부(7)에서 측정된 압력을 확인할 수 있도록 표시하는 압력표시부(9)를 포함하여 이루어지는 것을 특징으로 하며, 수압부를 통해 간단히 복횡근의 근력을 측정할 수 있게 되므로, 복횡근 근력 측정의 편리성을 일층 향상시킬 수 있게 된다.
