• It has long been assumed that the human central nervous system uses flexible combinations of a few muscle synergies to effortlessly and efficiently control redundant movements. Muscle synergies are defined as muscle groups in which the activation level of a set of muscles is specified collectively. However, muscle synergies are no more than conjecture and how such synergies contribute to motor performance is not clear. Here, we described the recent studies focusing on neuromechanics of muscle synergies and our approach to identify the existence of synergies based on motor output. Our results suggest that synergies are controlled to minimize the high-frequency force variability for required target directions by correlating the activity of synergies with target-directed endpoint force variability. Muscle synergies are not merely conjectural but that they actually exist in the neural circuitry and contribute to optimal force generations.
