The aim of this work was to compare the effects of fatigue of the quadriceps femoris after fatiguing voluntary contractions (VOL) and fatiguing neuromuscular electrical stimulation (ES) on bipedal postural control. Nineteen active male subjects (22.2 ± 1.7 years) completed these two fatiguing exercises. Isometric maximal voluntary contraction (MVC) and postural control were recorded using an ergometer and a force platform that registered the center of foot pressure (COP). We analyzed the COP… CONTINUE READING

In POST 5 condition , for both fatiguing exercises , muscle strength and postural control did not recover their initial level .
These results suggest that the postural control disturbance could not be distinguished for the two fatiguing exercises in the bipedal stance .
