Exertion due to dance creates phase-specific alterations of interlimb force coordination

Although the concept of coordination has received much attention, research on bilateral coordination between limbs has been focused on the upper extremity and reciprocal motion of the lower extremity. The bilateral occurrence of ground reaction forces presents an opportunity to investigate kinetic bipedal coordination. This would then lead to the characterization of typical force patterns and further the understanding of atypical movement due to altered demands or pathology. This study investigates how ground reaction force (GRF) coordination during sautés, a rate-controlled dance jump, changes due to exertion.
