A leg exercise device for physical education and training

Abstract

The invention relates to a leg exercising device for physical education and training, belonging to the technical field of multimedia interaction. The present invention provides a kind of leg exercising device, and this leg exercising device can intuitively reflect the student's leg movement through the trajectory line on the recording paper (the slope, length and time of the horizontal line on the recording paper point and time length can reflect the student's fatigue degree and load tolerance), and, when switching different load levels, this leg exercise device can respond to different brushes for trajectory line drawing, so this leg exercise device It can monitor the student's leg muscle fatigue after exercising for different periods of time under different loads in real time, and intuitively reflect the student's muscle fatigue law, so as to help the teacher understand the student's adaptation when switching between various load levels, so as to help the teacher Students specify a more scientific training plan.

Description

technical field [0001] The invention relates to a leg exercise device for physical education and training, belonging to the technical field of physical education and training. Background technique [0002] Physical exercise, especially leg exercise, is extremely important. Adequate exercise of the leg muscles can not only improve students' performance in sports such as running, long jump, and jump, but also reduce the probability of muscle strains in the above sports. [0003] At present, traditional leg exercise devices, such as pedals, treadmills, and elliptical machines, are still used for exercising the legs. However, these traditional leg exercise devices cannot real-time monitor the degree of muscle fatigue of the students' legs after exercising for different periods of time, nor can they reflect the degree of fatigue of the students' legs in a more intuitive way. Find the muscle fatigue law of students, let alone monitor the degree of muscle fatigue of students' leg...

Problems solved by technology

However, these traditional leg exercise devices cannot monitor the fatigue degree of the leg muscles of the students after different time periods of exercise in real time when the students are performing continuous exercise, nor can they reflect the fatigue degree of the students' legs in a more intuitive way. Find the law of muscle fatigue of students, let alone monitor the fatigue of students' leg muscles under different loads in real time when the gravity changes and switches repeatedly

[0004] Even if a leg exercise device with a heart rate measurement function is used, the trainer can only obtain physiological data such as the heartbeat and blood pressure of the student, but it is still impossible to monitor the student's leg muscle fatigue after exercising under different loads for different periods of time in real time, and, Intuitively reflect the law of muscle fatigue of students

The ensuing negative result is that the trainer cannot adjust the exercise intensity of the students in time according to the fatigue of the students' legs, which in turn leads to the strain of the students' leg muscles
