Example of training program, muscle synergy vectors, activation profiles, and endpoint forces pre- and post-training for one participant. Attributes of muscle synergies pre- and post-training are depicted in grey and orange, respectively. A Training program assigned to one participant with moderate severity. The table outlines the training movements and corresponding dosage, essential synergies, and control-specific synergies. B Muscle synergy vectors from the pre- and post-training assessment. The weight similarity scores for each synergy are shown on the right. C Synergy activation profiles from the pre- and post-training assessment. The essential and control-specific synergies are outlined in blue and green, respectively, for each of the trained directions. Arrows depict increases or decreases in activation levels of each synergy. The synergy activation scores for each of the trained movement directions are shown on the bottom, and the collective mean score is shown to the right. D Endpoint forces from the pre- and post-training assessment. The target and non-target directions are outlined in green and red, respectively, for each of the trained directions. Arrows depict increases or decreases in force of each direction. The force control scores for each movement direction are shown on the bottom, and the collective mean score is shown to the right. Bic: biceps brachii; Brd: brachioradialis; Tlo: long head of triceps brachii; Tla: lateral head of triceps brachii; PM: pectoralis major; MD: middle deltoid; AD: anterior deltoid; PD: posterior deltoid; Ant: anterior; Post: posterior; Med: medial; Lat: lateral; Sup: superior; Inf: inferior
