Interhemispheric inhibition (IHI) from right M1 to left M1 at rest and during muscle contraction of the left wrist flexors. The condition main effect suggests that IHI from right M1 to left (ipsilateral) M1 did not diminish at 50% MVC but IHI diminished (* p < 0.05) during shortening at 90% MVC relative to rest. During lengthening, IHI further diminished relative to all the other conditions († p < 0.05). Experiments were conducted at the same absolute force during lengthening and shortening, expressed as 50 and 90% of shortening MVC. Horizontal dashed line denotes control as 100%. S = shortening, L = lengthening.
