متن کاملThe Effect of Voluntary and Electrically Stimulated Quadriceps Muscle Fatigue on Postural Control
Purpose: The present study aimed to investigate the effect of voluntary and electrically stimulated quadriceps muscle fatigue on postural control. Methods: Sixteen healthy young males participated in this quasi-experimental study. All subjects performed two fatiguing exercises with equal intensity of isometric maximal voluntary contraction: Voluntary (VOL) and Electrical Stimulation (ES). The ...
متن کاملMyoelectric manifestations of fatigue in voluntary and electrically elicited contractions.
The time course of muscle fiber conduction velocity and surface myoelectric signal spectral (mean and median frequency of the power spectrum) and amplitude (average rectified and root-mean-square value) parameters was studied in 20 experiments on the tibialis anterior muscle of 10 healthy human subjects during sustained isometric voluntary or electrically elicited contractions. Voluntary contra...
متن کاملFatigue and Voluntary Utilization of Automation in Simulated Driving
OBJECTIVE A driving simulator was used to assess the impact on fatigue, stress, and workload of full vehicle automation that was initiated by the driver. BACKGROUND Previous studies have shown that mandatory use of full automation induces a state of "passive fatigue" associated with loss of alertness. By contrast, voluntary use of automation may enhance the driver's perceptions of control and...
متن کاملFatigue of intermittent submaximal voluntary contractions: central and peripheral factors.
Central and peripheral factors were studied in fatigue of submaximal intermittent isometric contractions of the human quadriceps and soleus muscles. Subjects made repeated 6 s, 50% maximal voluntary contractions (MVC) followed by 4 s rest until the limit of endurance (Tlim). Periodically, a fatigue test was performed. This included a brief MVC, either a single shock or 8 pulses at 50 Hz during ...
