A COMPUTER SOFTWARE FOR ANALYZING MUSCULAR DYNAMIC WORK STATE OF lOWER LIMBS

Abstract

The study of the kinematics and kinetics changes of muscular work state during exercise, such as in muscular length and its variable velocity and the arm of muscular force, is very useful in the research of sports biomechanics, sports anatomy, sports physiology and athletic training. It can not only enhance exploring the principle of exercise and muscular working characteristics, but also help working on the project of muscular strength training. A three-dimensional musculoskeletal database of the lower extremities has been used for human musculoskeletal models, which helps estimate the muscle forces that generate and control movement. However, these models are sensitive to changes in musculoskeletal geometry. Thus a realistic geometry is one of the initial steps in their development. By measuring the lower extremity origin and insertion 3D coordinates of corpses, this research forms statistical regressive equation between parameters of anthropometry and origin and insertion coordinates. Furthermore, it utilizes the principle of multiple geostatics to develop a computer analysis software for dynamic muscular work state of lower limbs.
