Abstract: Sports biomechanics is a discipline which studies the technical rules of sports by the principles and means of physics and physiology. It is very difficult to simulate the actual situation of the human body in the process of movement. At present, the simulation results of some modelling methods are not very satisfactory. According to the trend of flexion angle and muscle force, the changes of knee joint three-dimensional motion angle and muscle force in each analysis step were applied to the finite element model as boundary conditions. According to the specific analysis of the biological characteristics of human body, muscle force and joint force were predicted by using the model of bone-muscle system combined with non-invasive biomechanical experiments. We found that females had slightly higher adduction and internal rotation than males. When the knee flexion angle is about 90 degrees, the average adduction and external rotation angle of the subjects is almost the same. Sports biomechanics plays an important role in our training work and is a symbol of modern training. We should use it to better train technology, tactics and competitions.
