Neurophysiological insights on flexibility improvements through motor imagery
2017
International audience; The efficacy of motor imagery (MI) practice to facilitate muscle stretching remains controversial and the underlying neurophysiological mechanisms unexplored. We evaluated the effects of MI practice during a sit-and reach task. Healthy participants were randomly assigned to a MI practice (n = 15) or Control (n = 15) group and completed 2 blocks of 5 sit-and-reach trials. During the first block (B1), participants performed 5 maximal stretching trials of 10s. During the second block (B2), trials were divided into two consecutive parts: i) reproducing the maximum performance of B1 (10s, B2 part 1), and ii) attempting to outperform the maximum performance of B1 (10s, B2 …
Perception, Observation et Action
2015
L’observation d’actions est une caracteristique preponderante de l’Homme et de l’animal et participe grandement au developpement des habiletes motrices. Le fait de voir une tierce personne realiser un mouvement active le reseau des neurones miroirs, reconnus comme la base neurophysiologique de la comprehension des actions d’autrui. Dans cette revue, nous discutons, dans un premier temps, des reponses centrales et comportementales sous-jacentes a l’observation. Ensuite, nous decrivons les benefices et les limites d’un (re)apprentissage par observation. Enfin, nous presentons de nouvelles approches de la simulation d’actions combinant l’observation a d’autres operations mentales d’origine int…
Motor imagery and action observation following immobilization-induced hypoactivity: A narrative review.
2020
Abstract Background In sports, the risk of pathology or event that leads to an injury, a cessation of practice or even to an immobilization is high. The subsequent reduction of physical activity, or hypoactivity, induces neural and muscular changes that adversely affect motor skills and functional motor rehabilitation. Because the implementation of physical practice is difficult, if not impossible, during and immediately following injury or immobilization, complementary techniques have been proposed to minimize the deleterious impact of hypoactivity on neuromuscular function. Objective The current narrative review aimed to discuss the contributions of motor imagery and action observation, w…
