Fig 5. Linear regression between the onset of the single inhibition over the biceps brachii and the postural stabilization across the six series of the learning situation.

The postural stabilization was quantified using the MA expressed in % of the imposed unloading situation. The lower the percentages, the better the stabilization. The mean inhibition latency and the mean MA% measured during the imposed unloading situation and the voluntary unloading situation, which were not entered in the regression analysis, have been reported on the same graph.
