Anti-cheating abdominal board

Abstract

The invention discloses an anti-cheating abdominal board. The anti-cheating abdominal board comprises a board body, a supporting frame, a piezoelectric transducer, a photoelectric proximity switch andother parts. According to the anti-cheating abdominal board, the piezoelectric transducer is adopted for sensing a supination action, the photoelectric proximity switch is adopted for sensing a sit-up action, sensing of the two actions is counted, and the technical effects that the quality of supination and sit-up is improved, error actions in the training process are corrected, and cheating during supination and sit-up testing is avoided are achieved.

Description

technical field [0001] The invention relates to the field of sports equipment, in particular to an anti-cheating sit-up board. Background technique [0002] With the vigorous development of national fitness, people pay more and more attention to exercise. As a kind of physical exercise, sit-ups have the function of enhancing cardiopulmonary function and exercising the muscles of the waist and back. And sit-ups can be done at home, basically not limited by the venue, as long as simple equipment or even no equipment can be done. However, with the development of fitness culture, more and more people advocate fitness effects, and effective training is a necessary condition to achieve fitness effects. As the exercise progresses, doing sit-ups for a long time makes people do sit-ups faster and faster. When doing sit-ups quickly, the speed of lying down is bound to be fast, and it is easy to cause head or shoulder blades to be injured . At the same time, it is difficult to reme...

AI Technical Summary

Problems solved by technology

At the same time, it is difficult to remember the number of sit-ups done when you put in the exercise, and it is impossible to accurately calculate the speed of doing sit-ups

Moreover, during the exercise, due to fatigue, the movements when doing sit-ups are not standard, and the movements are not completely lying down or sitting up completely
