The present invention also provides an operation method of the sit-up training test device:

Before the test, the subject adjusts the position of the back support plate 3 to the right position, lies on the back pad 6, slightly separates his legs, and bends his knees to about 90 degrees. put on it. The back is close to the back pad 6, the arms are naturally straight and placed on both sides of the body, the palms of the palms are close to the hand rest 12, and the fingertips are against the fingertip baffle 13;

After starting the test, turn on the power switch of the test device, the subject lies in the adjusted position, and the time display area on the host 1 is ready for a 5-second countdown display. After the timing is over, the processor controls the buzzer 20 to issue a prompt. The sound prompts the start of the test, and the test timing is displayed in the timing display area, and the counting starts immediately. With the force of the abdomen, let the head and upper body slowly leave the ground, keep the arms straight, both hands drive the hand support 12 to move forward in a straight line, the magnetic marker 14 leaves the initial position of the magnetic induction sensor 15, and after passing through the second magnetic induction sensor 15, The waist and abdomen are then slowly exerted to restore the upper body to the state of lying flat, and the magnetic marker 14 will then return to the initial position. After one action is completed, the entire action needs to be completed within 3 seconds.

The host 1 detects the collected output signal of the magnetic detector, and judges whether the electrical signal is valid. During this process, if the foot pressure sensing pad 16 is always in a pressurized state in one action, the two magnetic induction sensors 15 sense in sequence. After reaching the magnetic marker 14 and outputting an electrical signal, and the time when the processor of the host 1 receives the complete signal is within 3 seconds, a sit-up has been completed, and the electronic controller of the host 1 increments the counter by 1 and continues timing; if The foot pressure sensing pad 16 is not under pressure, the sequence of the output electrical signals of the two magnetic induction sensors 15 is incorrect, or the signal collection time of the processor of the host 1 exceeds 3 seconds, it is determined that the action is not completed, and the timing and counting are stopped; during this period, the camera 2 Monitor the action.
