A kind of motion state analysis method and system

Abstract

According to the embodiment, the invention relates to a detection technology, and in particular to a sports state analysis method and a sports state analysis system. A foot pad which is provided with at least two sensors which are bilaterally symmetrical about a center line in a horizontal direction is used in the sports state analysis method, and the analysis method comprises the following steps: under a walking state, acquiring distance of each sensor away from the center line as well as a pressure value on each sensor; calculating the ratio of pressure at the left side to pressure at the right side of the foot pad in accordance with the pressure values of the bilaterally symmetrical sensors; and judging a current foot state in accordance with the pressure ratio in combination with a standard threshold, and outputting a guidance tip matched with the current foot state under the state that the pressure values are not equal to the standard threshold. With the application of the analysis method and the analysis system, the foot state of a sportsman can be accurately acquired and correction guidance can be offered to the sportsman, so that sports safety is enhanced.

Description

technical field [0001] Embodiments of the present invention relate to detection technologies, and in particular to a motion state analysis method and system. Background technique [0002] Jogging exercise is the most commonly used physical exercise method. More and more residents exercise their cardiopulmonary function, bones, etc. through jogging. During jogging, before the feet hit the ground, the knees and soles buffer the huge pressure of the body at the same time, and the inner side of the heel is under pressure when the heel hits the ground. At this time, the outer side of the foot is relatively "flexible" (and the forefoot, reorganization can freely choose the landing position) ; When the midfoot and forefoot touch the ground, the outer side is under pressure; the moment the foot is pushed off the ground again, the foot is adjusted to a stable state, and the hip joints, knee joints, and ankle joints become stable again. However, when the pressure on the sole of the f...

Problems solved by technology

However, when the pressure on the sole of the foot is excessively distributed on the inside, it is easy to cause the foot to turn outward; otherwise, it is easy to cause the foot to rotate inwardly, and at the same time, the internal rotation or outward turn of the foot also drives the internal rotation or outward turn of the knee, which is further controlled by the calf muscles. Foot pronation or valgus forms a vicious cycle. Long-term foot valgus or valgus can easily lead to plantar fasciitis, ankle joint injury, calf muscle involvement, etc. In addition, foot valgus or valgus also drives knee inversion Rotation or eversion greatly reduces the safety during exercise
