How Mental Rehearsal Can Increase Strength
Mental rehearsal can cause increases in strength, but they are never as great if done alone. What mental rehearsal appears to do is engage the activity of those upper motor neurons that we talked about way back at the beginning of the episode. The ones that generate the actual movement are the lower motor neurons and the central pattern generators....
This episode I discuss the science and practice of learning physical skills: what it involves at a biological level, and what to focus on during skill learning at each stage to maximize learning speed and depth. I also describe what to do immediately after a training session (note: this is different than the optimal protocol for cognitive skill training) and as you progress to more advanced levels of performance. I also cover the science of skill-based visualization which does have benefits, but only if done correctly and at the correct times. I discuss auto-replay of skill learning in the brain during sleep and the value of adding in post-training ‘deliberately idle’ sessions. I cover how to immediately improve limb-range-of-motion by leveraging cerebellum function, error generation, optimal repetition numbers for learning and more. As always, scientific mechanism, peer-reviewed studies and science-based protocols are discussed.
