Description

technical field [0001] The invention relates to the field of sporting goods, in particular to a youth sports device and an automatic counting method thereof. Background technique [0002] Sit-ups are a routine item in sports testing, mainly testing the endurance of the waist and abdomen of the testee. Now the school tests sit-ups, usually using a mat, the testee lies on the mat, and a classmate presses the testee feet, and then start timing. The testee does sit-ups, and the student who presses the feet is responsible for counting. The test method is completely done manually, and the counting efficiency is low and there are errors. [0003] The current sit-up testing instrument uses a human body posture sensor for recognition. The test efficiency of this sensor is low, and it is easily disturbed by external actions, resulting in low test accuracy. Contents of the invention [0004] In view of the above technical problems, the present invention proposes a youth sports devic...
