Full textThe purpose of this PhD research is, on the one hand, to study the neural drive specificities during eccentric contractions by exploring the neural mechanisms involved at spinal level and, on the other hand, to examine the neural mechanisms responsible for the modulations of neuromuscular system following a strength submaximal eccentric training. Through this PhD research we highlight the contribution of recurrent inhibition by the Renshaw cell to the decrease of muscular activation typically observed during eccentric contraction. Furthermore, we show that recurrent inhibition is enhanced during submaximal contractions regardless of the contraction type. These results emphasize the important role of recurrent inhibition in the specificity of neural control during eccentric contractions. We confirm that the neural drive of the eccentric contraction may be modulated by eccentric strength training although modulations of spinal excitability seem to depend on the characteristics of training

Full textThe purpose of this study was to examine some physiological muscle adaptations to strengthening. The effects of monoangular isometric strength training using Electrical Stimulation (ES) or Voluntary Contraction (CV) upon the Torque-Length relationship and the electromyographic activity of the agonist and antagonist muscles were compared. Maximum Voluntary Isometric Force was significantly increased beth by electrical stimulation and voluntary contraction. The two training modes yielded similar results when the electrically evoked torque and the isometric flexion torque exerced on the ergometric device, along the training sessions were equal. In this way, the increase of voluntary strength was specific to the training angle with beth training procedures. Moreover some electromyagraphic evidence was revealed with ES and CV training indicating a greater increase in the motor unit activation of the agonist at the training. So that, a neural adaptation to training seems to be unavoidable even with electrical stimulation training. This neural mechanism would be driven by the level of the isometric torque exerced on the ergometric device. We emphasize the rôle of the postural muscle in the process of strength development

Full textTwo lattice autoregressive different techniques are used to represent EMG signal during two types of experiences : isometric sustained voluntary contractions induced by transcutaneous electrical stimulation, both on the biceps brachial. On first, the signal is slowly non stationary and is identified by pieces, and in the second case, a covariance algorithm is used to process the local non stationnarity of a response, and then of its time drift. There are different interest contained in this method : good reproductibility (low order), cheap microsystem equipment, real time monitoring and quantification of fatigue. Thanks to stimulation, different parts have been detected during experiences, and are discusses from a physiological and from a signal entropy point of view

Full textThe realization of a motor action involves simultaneous activation of both agonist and antagonist muscles controlled by the central nervous system. Following spinal cord injury, damage to the spinal cord causes both a loss of motor efficiency and changes in the control of muscle activations. In the present work, we studied the reorganization of muscle activations, cortical activations and corticomuscular interactions (ICM) in spinal cord injured (SCI) and able-bodied (AB) participants during voluntary isometric contractions in flexion and extension around the elbow joint. In extension, our results showed altered capacity of maximum force production in SCI participants, associated with increased muscle activations, similar cortical activation and decreased involvement of M1 in the control of muscle activations when compared to AB participants. In flexion, the force capacities, cortical activations and ICM were similar between SCI and AB participants, but the activation of antagonistic muscles and the difficulty to inhibit the contraction were greater in SCI participants. For all participants in flexion, ICM were different depending on the function of the muscle groups. Taken together, these results suggest an alteration of the cortical control of spinal inhibitory mechanisms following a spinal cord injury, but suggest that the motor cortex remain functional to control a motor act despite the atrophy of the extensor muscles. These results could find clinical applications for the development of neuroprotheses involving simultaneous control of different muscle groups

Full textThe overall objective of this thesis was to compare the effect of fatigue of the quadriceps femoris after fatiguing voluntary contractions (VOL) and fatiguing neuromuscular electrical stimulation (ES) on bipedal postural control, and central fatigue. The results show that after unilateral or bilateral muscle fatigue, the ES exercise affected the muscle strength more than the VOL exercise. However, bipedal postural control was similarly deteriorated for both exercises. Moreover, the recovery speeds of postural control and muscle strength abilities did not differ for the both exercises. In addition, the VOL exercise alters central drive quicker than the ES exercise immediately after their completion while the ES exercise delays and prolongs the central fatigue. As the VOL exercise is induced by central command and the ES exercise is generated by artificial external stimulation, one can hypothesize that the VOL exercise especially produces supraspinal fatigue, while the ES exercise especially engenders spinal fatigue
