Abstract
Human biomechanics has practical value in the fields of medicine, sports and bionics. In order to explore the influencing factors of the maximum force exertion ability of human joints, the elbow joint in the human upper limb joint was selected as the research object, and a mathematical model of the maximum force exertion ability of the human elbow joint was established. In this paper, elbow angle, direction of movement, adjacent joint (shoulder) angle and type of movement (isometric and isokinetic motion) were selected as independent variables, and maximum torque and muscle activation were selected as dependent variables. The elbow data were collected from 31 men through elbow bend/extension isometric and isometric MVT tests. Then, the basic statistical indicators such as mean, standard deviation, maximum and minimum values of the dependent variable were calculated, and draw a bar chart for data visualization. Finally, the experiments have found that under different conditions, the maximum force and muscle activation values of the elbow joint are significantly different. From the analysis of the results, it can be seen that the angle of the adjacent joint and the type of movement can significantly affect the ability of the elbow joint to exert force. The direction of movement and the angle of the adjacent joint can significantly affect the activity of the main force muscles of the upper limb.
