Description

technical field [0001] The invention relates to the field of sports biomechanics, in particular to a sports biomechanics coupling analysis system. Background technique [0002] Sports biomechanics focuses on the exploration of the mechanism and law of biological movement, which is the basis for revealing the mystery of the principle of movement of living bodies. However, because the organism is a complex, non-linear, adaptive life system, there are still many problems to be solved urgently in the study of sports biomechanics due to the limitations of individual differences, variety of sports forms and in vivo experiments. In terms of theoretical research, the establishment of a biomechanics model is the key to theoretical research. At present, most sports biomechanics studies use multi-rigid body or skeletal muscle models to simulate the form of biological movement and estimate the load and movement of joints, bones and muscles during exercise. However, due to many simplifi...

Problems solved by technology

However, because organisms are complex, non-linear, adaptive life systems, there are still many problems to be solved in the study of sports biomechanics due to individual differences, diversity of sports forms and limitations of in vivo experiments.

In terms of theoretical research, the establishment of a biomechanics model is the key to theoretical research. At present, most sports biomechanics studies use multi-rigid body or skeletal muscle models to simulate the form of biological movement and estimate the load and movement of joints, bones and muscles during exercise. However, due to many simplifications and assumptions in these mechanical models, coupled with the unclosed nature of mechanical equations, the unmeasurable theoretical error, and the difficulty of simulation, it is still difficult to use theoretical methods to study biological movement. there are big flaws

In terms of experimental testing, most of the test methods are single or paired. Although some kinematic or dynamic parameters of biological movement can be obtained, it is not possible to conduct comprehensive, simultaneous measurement and analysis of mechanical performance parameters of biological movement. In addition to the complexity of the analysis of test data, the inevitability and non-repeatability of test errors, and other reasons, the test method alone cannot make up for the lack of research results.
