This area of skill development came up in today's seminar with mc - which I will write more of soon (it was excellent) - but I also came across this today which is relevant to the discussions:
Study shows new brain connections form rapidly during motor learning
New connections begin to form between brain cells almost immediately as animals learn a new task, according to a study published this week in Nature. Led by researchers at the University of California, Santa Cruz, the study involved detailed observations of the rewiring processes that take place in the brain during motor learning.
When you are learning a new physical skill, you are re-wiring your brain....and to some degree this is permanent.
"It's a remodeling process in which the synapses that form during learning become consolidated, while other synapses are lost," Zuo said. "Motor learning makes a permanent mark in the brain. When you learn to ride a bicycle, once the motor memory is formed, you don't forget. The same is true when a mouse learns a new motor skill; the animal learns how to do it and never forgets."
Interesting stuff. You need to learn the skill....but that learning gets hardwired into the brain and stays there. As mc said today, the nervous system is plastic.

The idea of learning *new* skills this way is one thing, and the first poster makes a good point about it being a bit obvious. But I wonder about the application of this to *improving* at a skill you already have. For example, Pavel often talks about "greasing the groove" by doing a high volume of sub-maximal reps with an exercise. Is this an application of the above?
Chris,
Frank from Exuberant Animal posted an interesting presentation on motor control and variation

Chainey - well spotted, the "literally" thing annoys me too. I have removed it.
Hi Chris. This is part of my training concept...the idea that the brain is pliable. The brain releases the same learning proteins and chemicals while performing (learning) a complex motor skill, as it does learning math, or another language. Dr. John Ratey did research for this in his practice, and many school systems across America have implemented his research in their classrooms...FINALLY! The book is called "Spark." I highly recommend it. Nice post (as always!)
Brahma:
Yes, it is a similar concept. Doing thousands of reps (correctly) at a very submax level will stimulate more thorough, stronger, quicker neurological connections in the brain. Just like your brain creating memory pathways when learning math...isn't 2 + 2 always 4? But we had to learn that by repeatedly doing the homework. Submax exercises are the homework from which we can apply more intense (higher weight) efforts...IMO.
Like riding a bike.
I fly hang-gliders, sailplanes & power. I've had a year or more go in-between flights, sometimes, but it just never seems to matter. Far more important than the "muscle memory" are safety procedures.
Oh, on "literally" abuse:
