Dance training improves the CNS’s ability to utilize the redundant degrees of freedom of the whole body

Abstract Professional dancers demonstrate an amazing ability to control their balance. However, little is known about how they coordinate their body segments for such superior control. In this study, we investigated how dancers coordinate body segments when a physical perturbation is given to their...
