The magnetic induction sensor 15 is composed of a magnetic sensing unit, an electric signal conversion unit and an electric signal output module, and the magnetic induction sensor 15 and the camera 2 are electrically connected with the host 1 through a cable 17. When the magnetic sensing unit senses the magnetic label 14, the magnetic sensing unit converts the signal into an electric signal and transmits the electric signal to the host 1.

The inside of the host 1 is provided with a timing and counting device, a card swiping area 18, a display 19 and a buzzer 20 besides a control device; the electronic control device sets the trunk forward-bending counting logic, and comprises the following steps: the subject begins the test and the display screen 19 makes a ready countdown display; after the timing is finished, the buzzer 20 gives a prompt, and the display screen 19 carries out test timing display; the electronic control device receives output signals of the camera 2, the magnetic induction sensor 15 and the foot pressure sensing pad 16, successfully completes one forward bending action, and the counter is increased by 1; when the subject does not complete an action within the prescribed time, the test is ended and the display 19 displays the results. The card swiping area 18 reads the identity card of the experimenter and is used for distinguishing the identity of the experimenter. The electrical components all adopt the prior art.

The back supporting mechanism is provided with a back supporting plate 3 and a pair of back adjusting slide ways 4, the back adjusting slide ways 4 are fixed with lower limb supporting plates 21, sliding grooves 5 are formed in the back adjusting slide ways 4, and the back supporting plate 3 is matched with the sliding grooves 5 through pulleys 22; the back support plate 3 is provided with a back cushion 6.

The invention also provides an operation method of the sit-up training test device, which comprises the following steps:

before testing, the subject adjusts the position of the back splint 3 to lie on the back pad 6 with the legs slightly separated and the knees tucked around 90 degrees to lay the feet flat on the foot pressure sensing pad 16, but without the buttocks resting thereon. The back is clung to the back cushion 6, the arms are naturally straightened and put on the two sides of the body, the palms of the two hands are clung to the hand rest 12, and the fingertips are clung to the fingertips baffle 13;

after the test is started, the power switch of the test device is turned on, the subject lies on the adjusted position, the time display area on the host computer 1 is prepared for counting down for 5 seconds, after the counting is finished, the processor controls the buzzer 20 to send out a prompt tone to prompt the test to start, and meanwhile, the counting display area is used for carrying out test counting display, and counting is started immediately. With the force applied from the abdomen, the head and the upper body are kept to be straightened, the hands drive the hand rest 12 to move forward linearly, the magnetic mark 14 is separated from the magnetic induction sensor 15 at the initial position, after passing through the second magnetic induction sensor 15, the waist and the abdomen slowly enable the force to restore the upper body to a lying state, the magnetic mark 14 returns to the initial position, one action is finished, and the whole action is completed within 3 seconds.

The host 1 detects the output signals of the collected magnetic detectors and judges whether the electric signals are effective, in the process, if the foot pressure sensing pad 16 is always in a pressed state in one action, the two magnetic induction sensors 15 sense the magnetic marks 14 in sequence and output the electric signals, and the time that the processor of the host 1 receives the complete signals is within 3 seconds, one sit-up is completed, the electronic controller of the host 1 enables the counter to be added with 1, and the timing is continued; if the foot pressure sensing pad 16 is not in a pressed state, the output electric signals of the two magnetic induction sensors 15 are not in sequence or the signal collection time of the processor of the host computer 1 exceeds 3 seconds, judging that the action is not finished, and stopping timing and counting; during this time, the camera 2 monitors the operation.
