Jono, nobody says an athlete with more nervous control doen't run faster than an athlete not having the same level of control, this is not the point.
The point is your idea that metabolic situation can't change with proper training.
For example, the fact top athletes can increase of 25% their total volume of blood, what has to do with the neural pathways ?
We work for recruiting the higher percentage of fast fibers when are full of lactate. For that reason we use circuits, many times uphill, without solution of continuity, where athletes alternate running at high intensity (for instance, short sprint of 60m) with specific exercises, requiring good ability to control the technical execution.
An example, using 400m uphill with a gradient of 8-10% :
60m sprint + 40m skippig fast + 60m sprint + 40m heels-to-buttocks + 60m sprint + 40m bounding + 100m sprint + 10 squat-jump at the end, carried out at the max intensity. We use, with 800m runners during the Fundamental and Special period, from 5 until 7 repetitions with recovery of 5'/6' in between, not enough for maintaining lactate at the same level, every time the athlete starts the next circuit.
For that reason, we have continuous ACCUMULATION of lactate, and we train the nervous system to increase the ability to recruit fast fibers when the fibers themselves become saturated with high quantity of lactate.
The athlete learn how to control his technique under a higher quantity of lactate, in my opinion increasing the TOLERANCE referred to the nervous system, connected with the metabolic system.
I really don't understand a practic workout that can satisfy your thesis only, without inclusion of metabolic changes in the activity of the athlete.
But may be you have reason. Can you give us the example of some workout specific for training neural pathways ?
Thank you in advance.
