Strength training and rehabilitation

Most strength-based sports performances are not only about strength. They are about the right strength. Ths is because muscles are heavy, and there is no need to add muscle mass that does not add to the performance. The AnyBody Modeling System can help identify the muscles that are currently the bottleneck for performance improvment, and it can subsequently design exercises for improvement of precisely these muscles.

After an injury to a joint or a ligament, it is often desirable to strengthen the muscles surrounding the joint in question to stabilize the joint. But how can this be done without causing undue loads on the injured elements? Let us consider a simple load on the foot and examine how the position of this load influences the shear forces in the knee. Here show a video animation of the moving force and the corresponding muscle loads in the leg.

If we subsequently investigate the computed knee shear forces, which are carried by the cruciate ligament, then it turns out that the force location under the foot plays a very important role, and indeed there is one particular position of the foot force that completely eliminates the knee shear force.
