Effect of the experimental conditions on the <i>EMG</i>–pattern.

<p><i>EMG</i>-patterns of soleus (<i>Sol</i>), tibialis anterior (<i>TA</i>), gastrocnemius lateralis (<i>GL</i>), peroneus brevis (<i>PB</i>), vastus lateralis (<i>VL</i>) and biceps femoris (<i>BF</i>) muscles are presented from 450 ms before <i>TD</i> to 250 ms after <i>TD</i>. Positive traces are for the 1 <i>g</i> and the <i>SLS</i>-conditions and negative traces for the <i>A300</i>-condition. Black line is for 1 <i>g</i>; blue lines are for 1.2 <i>g</i>, green for 1.4 <i>g</i> and red for 1.6 <i>g</i>. Traces are the grand mean of the eight subjects averaged over periods of 5 ms and are synchronized to <i>TD</i> (vertical interrupted line). Dotted vertical colored lines correspond to the <i>TO</i> (same color than the curves) in each condition.
