• Resumen

  • Several methods have been proposed to solve the �redundancy problem in biomechanics,� optimization techniques that are being most widely used. In posing the optimization problem, a variety of cost functions can be found in the literature, designed to meet various criteria, whether to minimize muscle fatigue, active or passive instant muscle strength, the level of muscle activation, or metabolic cost. The aim of this paper is to compare muscles forces generated by different cost functions. We have studied the forces produced by the muscles of the human leg during flexion, using a static optimization algorithm, accounting for the dynamics of muscle contraction.
