“…Firstly, at a functional level, motor imagery practice seems to induce positive changes within motor planning [ 40 , 41 ]. Indeed, via the activation of the neural network implicated in motor planning, motor imagery training could help to refine the internal representation of the considered action by the generation of sensorimotor predictions, leading to an improvement of motor command [ 42 , 43 , 44 ]. Secondly, the modulation observed at both the neural [ 45 ] and spinal [ 46 ] levels during motor imagery seems to reinforce the sensibility and the conductivity of synapses in the corticospinal pathway [ 47 ], notably by increasing the effectiveness between pre- and post-synaptic neurons.…”

Human aging is associated with a decline in the capacity to memorize recently acquired motor skills. Motor imagery training is a beneficial method to compensate for this deterioration in old adults. It is not yet known whether these beneficial effects are maintained in very old adults (>80 years), who are more affected by the degeneration processes. The aim of this study was to evaluate the effectiveness of a mental training session of motor imagery on the memorization of new motor skills acquired through physical practice in very old adults. Thus, 30 very old adults performed 3 actual trials of a manual dexterity task (session 1) or a sequential footstep task (session 2) as fast as they could before and after a 20 min motor imagery training (mental-training group) or watching a documentary for 20 min (control group). Performance was improved after three actual trials for both tasks and both groups. For the control group, performance decreased in the manual dexterity task after the 20 min break and remained stable in the sequential footstep task. For the mental-training group, performance was maintained in the manual dexterity task after the 20 min motor imagery training and increased in the sequential footstep task. These results extended the benefits of motor imagery training to the very old population, showing that even a short motor imagery training session improved their performance and favored the motor memory process. These results confirmed that motor imagery training is an effective method to complement traditional rehabilitation protocols.

Pour favoriser la performance, certains entraîneurs ont souvent recours au feedback (FB) verbal, à l’Observation d’un Modèle (OM) ou à l’imagerie motrice (IM) consistant à simuler mentalement réaliser une action. Cette étude avait pour but de tester les effets d’une combinaison de FB, d’OM et d’IM sur la performance du 25 m départ plongé en natation chez des non-experts. Cent-six étudiants volontaires (Mage = 19,3), aléatoirement divisés en 3 groupes : FB, FB+OM et FB+OM+IM, ont réalisé 3 phases réparties sur 6 séances. Séance 1 (pré-test), ils ont réalisé 5 × 25 m départs plongés (filmés et chronométrés). Les 4 séances suivantes (8 × 25 m départ plongé), ils recevaient un FB verbal (chaque 2 essais), ceux du groupe FB+OM bénéficiaient en plus de la vidéo et ceux du groupe FB+OM+IM s’imaginaient réaliser un plongeon après la vidéo. Séance 6 (post-test) : similaire à la séance 1. Les résultats montrent que tous les participants ont amélioré leur vitesse de coulée, mais seul le groupe FB+OM+IM a amélioré la distance de coulée et le temps sur 25 m. L’intérêt de combiner les modalités de pratique, pour améliorer le 25 m départ plongé, est discuté au regard de la littérature.
