Long-term repetitive activities or incorrect postures make muscles bear continuous stress and the incidence of chronic injury of human muscle tissue is high. In this paper, the research status of muscle tissue morphological model, biophysical model, chronic injury analysis and data collection are reviewed. Muscle shape model is mainly based on line segment, volume and surface modeling methods, muscle dynamic modeling methods are worthy of further exploration. Muscle biophysical properties are based on muscle biological tests, and more efforts are needed to accurately describe the biophysical properties of muscle groups. The model of chronic muscle injury is mainly based on MRI data, and simulation experiments are carried out with the help of simulation platform and algorithm, which can further enhance simplification and optimization of calculation methods. A variety of measuring equipment such as myoelectrometer and depth sensor can be used for acquisition of physical quantities such as muscle deformation and force, and more innovations are expected in data fusion methods and algorithms. Finally, when studying chronic injury of muscle tissue, correct description of the morphology and mechanical properties of muscle tissue is the key to accurate results.
