Figure 3. Synergy activation coefficients and muscle synergy vectors depicted for rowing on SE and FE. Synergy activation coefficients were averaged across the subjects for the three extracted synergies and expressed as a function of percentage of the rowing cycle (0% to 50% represent drive phase and 51% to 100% represents recovery phase). The muscle synergy vectors were averaged across the subjects for the three extracted synergies. Individual muscle weightings are depicted for each muscle within each synergy. SE, slides ergometer: FE, fixed ergometer.
