Problems solved by technology

Especially in the field of basic training for young athletes, due to the lack of scientific and quantitative guidance based on real-time collection of sports data and real-time analysis of sports force, wrong movements and unreasonable training volume will cause tendon abnormal force. tendon injury, so many elite athletes have to withdraw from the training ground

Embodiment Construction

[0038] The present invention will be further described below in conjunction with accompanying drawing.

[0039] Such as figure 1 As shown, a method for early warning and analysis of tendon abnormal stress injury with real-time collection of motion data includes the following steps:

[0040] Step 1. Build a joint anisotropic force analysis model. The movement direction and movement angle of each joint of the human body are limited by the physiological constraints of bones and tendons. Quantitatively analyze the movement direction, position and physiological limitations of the limbs by building a model. Specifically include the following sub-steps:

[0041] (a) Define the upstream and downstream relationship and coordinate system of the limbs. A person standing upright on the ground can be regarded as 16 rigid body models, specifically the chest, abdomen, hip, head, left and right upper arms, left and right forearms, left and right thighs, and left and right calves , hands, an...

Abstract

The invention relates to an injury early warning analysis method. The early warning analysis method for tendon anisotropic stress injury based on real-time sports data acquisition comprises the following steps: (1) joint anisotropic stress analysis model construction; (2) joint anisotropic stress boundary description; (3) practical calibration of the joint anisotropic stress boundary; (4) anisotropic stress judgment in the joint movement process; (5) joint anisotropic stress alarm judgment. The early warning analysis method provided by the invention has the benefits that joint upstream and downstream attitude data is measured in real time through a wearable sensor, key joint anisotropic stress data is calculated, the overrun, the amplitude and the number of a sportsman in the training process are calculated and judged according to the joint sports space limit of the joint anisotropic stress analysis model, and an alarm judgment on anisotropic stress is given; therefore, the sports injury of the sportsman during training is defectively reduced.

Description

technical field [0001] The present invention relates to an injury early warning analysis method, and more specifically, relates to an early warning analysis method of tendon anisotropic stress injury with real-time collection of motion data. Background technique [0002] In professional sports training, sports injury is an unreasonable training method. The wrong training mode will cause athletes to be injured in light cases, and in severe cases will cause athletes to end their sports career. At present, many sports training subjects are taught by the coaches' precepts and deeds. The coaches guide the athletes' training based on visual inspection and experience. Especially in the field of basic training for young athletes, due to the lack of scientific and quantitative guidance based on real-time collection of sports data and real-time analysis of sports force, wrong movements and unreasonable training volume will cause tendon abnormal force. Tendon injuries caused many elit...
