Figure 6From: Load emphasizes muscle effort minimization during selection of arm movement directionMean values of I INTE , I INTS , I IR , and I E during performance of the task with the dominant (D) and nondominant (ND) arm without and with load. There was a significant effect of arm (indicated by *) on mean I INTE and significant effect of load (indicated by **) on mean I INTS . The vertical bars on the top of the columns represent SD.Back to article page
