Résumé
Current study attempted to clarify whether preceding muscle activity influences the perceptually guided force production during superimposed ballistic contractions using isometric abduction of index finger. Subjects were verbally asked to produce ballistic force at requested percentages of their MVC with and without preceding muscle activity at 10% and 20%MVC. Our results showed that the ballistic force and EMG activity were increased significantly with preceding muscle activity at 20%MVC, but no change for 10%MVC. These results suggest that preceding muscle activity at sufficient intensity facilitates spinal motoneuron excitability, which could alter the relationship between the produced force and sense of effort.
