The core stability exercise management system may comprise: at least one detection unit for detecting the force at which the abdominal muscles contract and push a pressure sensor; a reference value control unit for, if the abdominal muscles are maximally contracted, receiving the maximum value measured by the detection unit, calculating a reference value which is 1/n (n is a real number) of the maximum value, and displaying the reference value in every corresponding section on a display device; and a measurement value control unit for receiving a measurement value detected by the detection unit according to the contraction and relaxation of the abdominal muscles, and displaying the measurement value on the display device on which the reference value is displayed. ## Claims ### Claim 1 A core stability exercise management system comprising: at least one sensor for sensing force of pushing a pressure sensor after abdominal muscles contract; a reference value controller for receiving a maximum value measured in the sensor when the abdominal muscles contract to the maximum, calculating a reference value, which is 1/n (n is a real number) of the maximum value, and displaying the reference value on each corresponding section of a display device; and a measured value controller for receiving a measured value sensed from the sensor according to contraction and relaxation of the abdominal muscles and displaying the measured value on the display device where the reference value is displayed. ### Claim 2 (depends on 1) The core stability exercise management system of claim 1, wherein the reference value controller alternately displays the reference value and an initial value measured by the sensor in the state, where the abdominal muscles do not contract, on the display device and the measured value controller displays the measured value sensed in the sensor according to contraction and relaxation of the abdominal muscles on the display device, in response to sections where the reference value and the initial value are displayed. ### Claim 3 (depends on 1) The core stability exercise management system of claim 1, wherein the sensor comprises: a cover filled with incompressible fluids in an inner part thereof which is sealed by an elastic side; and a pressure sensor combined to the inner part of the cover which is filled with the incompressible fluids for sensing pressure delivered through the incompressible fluids when force is applied to the cover from the outside. ### Claim 4 (depends on 3) The core stability exercise management system of claim 3, wherein the pressure sensor is combined to the elastic side within the cover or is placed in the space where the incompressible fluids, and transmits the sensed value to the reference value controller or the measured value controller through wired communications or wireless communications. ### Claim 5 (depends on 3) The core stability exercise management system of claim 3, wherein the sensor further comprises a supporter which is made with a non-elastic material and is combined to one side of the cover for supporting the one side of the cover. ### Claim 6 (depends on 3) The core stability exercise management system of claim 3, wherein the cover comprises an elastic side, to which the force is applied from the outside, and at least one non-elastic side except for the side, to which the force is applied. ### Claim 7 (depends on 1) The core stability exercise management system of claim 1, further comprising: a notice controller for providing notice when a difference between the measured value and the reference value is over a threshold value. ### Claim 8 (depends on 1) The core stability exercise management system of claim 1, wherein the at least one sensor is combined to a belt and thus, closely adhered to the abdominal muscles.
