From: Muscle synergies are shared across fundamental subtasks in complex movements of skateboarding
Synergy vectors and activation coefficients which were shared across all three tricks of all participants (P1 … P7) based on the sharedIND method; y-ticks (0–1) are the muscle weightings (left subplots) or level of activation (right subplots) for synergy vectors or activation coefficients. Each waveform indicates the average activation coefficient across trials per trick. The time interval between the lowest (0%) and highest (100%) point of the sacrum cluster marker was analyzed (% of observed movement, see supplementary Figures S1). f = front leg; b = back leg.
