Analysis around the elbow joint during extension and flexion motions by musculoskeletal mathematical model

Abstract

In recent years, the proportion of elderly people is increased. And people who enjoy the sports is increased. To keep fit for elderly people, to enjoy playing sports without injuries and to raise exercise performance, exercise must be done effectively. Previous research is being carried out methods for estimating muscle torque and muscle tension on the basis of a musculoskeletal model. As a result, it has become possible to quantitatively identify the extent of fatigue in each muscle during motion. Therefore, to evaluate muscle fatigue more quantitatively, driving power and angular momentum are focused on. Driving power is considered to be a value for evaluating actual kinematic performance around a joint motion as energy per unit of time, and angular momentum exerted by each muscle expresses the intensity of motion of that muscle. This method is applied to analysis of extension and flection around elbow joint with dumbbell and without dumbbell.
