2. Fig. 1
Evolution of the contraction force during 10 minutes of stimulation of the iliococcygeus when different on-off time ratios were used. The results are expressed as mean remaining force, relative force (%) of the initial maximal isometric tension, after 5 and 10 minutes of stimulation (n = 9): ●, 3 on 40 off; ■, 3 on 30 off; ▴, 3 on 20 off; ▾, 3 on 10 off.

Evolution of the contraction force during 10 minutes of stimulation of the pubococcygeus when different on-off time ratios were used. The results are expressed as mean remaining force, relative force (%) of the initial maximal isometric tension, after 5 and 10 minutes of stimulation (n = 9): ●, 3 on 40 off; ■, 3 on 30 off; ▴, 3 on 20 off; ▾, 3 on 10 off.

Evolution of the contraction force during 10 minutes of stimulation of the soleus when different off time ratios were used. The results are expressed as mean remaining force, relative force (%) of the initial maximal isometric tension, after 5 and 10 minutes of stimulation (n = 9): ●, 5 on 40 off; ■, 5 on 30 off; ▴, 5 on 20 off; ▾, 5 on 10 off.

Evolution of the contraction force during 10 minutes of stimulation of the soleus when different on-off time ratios were used. The results are expressed as mean remaining force, relative force (%) of the initial maximal isometric tension, after 5 and 10 minutes of stimulation (n = 7): ●, 10 on 20 off; ■, 20 on 20 off; ▴, 10 on 30 off; ▾, 20 on 30 off.
