Abstract

The optimum angle refers to the joint position at which the maximum peak occurs at the moment of force within the joint angle-time curve. This parameter can be used to estimate changes in the force-length curve of a muscle group. The optimum angle can be obtained from measurements in isometric and dynamic tests, and this should be taken into account when making comparisons. The optimum angle can be altered both acutely and chronically. The main factors that modify it are the intensity and volume of exercise, muscle length, contraction mode and velocity of contraction. The ability to evaluate and modify the optimum angle can be used in programmes for the prevention of muscle injuries, especially in team sports like football. This review examines and discusses the studies found in the literature related to this topic.
