From: Muscle synergies are shared across fundamental subtasks in complex movements of skateboarding

Mean (bars) and standard deviation (error bars) of the original and reconstructed total variance accounted for (tVAF). Top subplots show original tVAF and tVAF of reconstructed synergy vectors (W, subplot a) or activation coefficients (C subplot b) from other participants or random inputs. Bottom subplots: original tVAF and tVAF of reconstructed W (subplot c) or C (subplot d) from other tricks (trick 1 and trick 2).
