Muscle coactivation occurs when agonist and antagonist muscles (or synergist muscles) surrounding a joint contract simultaneously to provide joint stability. It is also known as muscle cocontraction, since two muscle groups are contracting at the same time. It is able to be measured using electromyography (EMG) from the contractions that occur. The general mechanism of it is still widely unknown. It is believed to be important in joint stabilization, as well as general motor control. (en) La coactivation musculaire est un phénomène décrivant l'activation simultanée de deux muscles agoniste/antagoniste lors d'un mouvement. La coactivation musculaire est utile pour limiter l'amplitude des mouvements et augmenter la précision. Lorsque ce phénomène est mal géré, par exemple lorsqu'un muscle agoniste est hypertrophié, il y a un risque de dommages ligamentaires. À l'inverse la coactivation musculaire peut être néfaste dans le cas de performances sportives (par ex. la course à pied), car elle diminue le rendement musculaire. Ceci se produit notamment si le sportif n'arrive pas à gérer le stress de la compétition. (fr) |
