The system craves overload to encourage progression.
There is a place for technical “drills” but as soon as it’s mastered move on.
The brain needs stimulating.
“I’ve walked millions of steps over time but that doesn’t make me an expert walker. Repetition of a skill has to be purposeful and variable”
An organism isn’t interested in a stimulus it considers mundane.
For effective learning to occur all non reflexive stimuli must clear the RAS [Reticular Activating System].
This is in simple terms is the ‘ON’ button for the brain and motor learning.
Doing the same mundane non stimulating drills without progression will never turn on the ‘ON’ button.
This is why a lot of fast bowlers fall out of favour with technical work.
The drill isn’t the issue, it’s the lack of understanding from the coach on how the brain works and whats needed to encourage adaptation and progression.
Movement must have degrees of freedom to promote learning and progression.
In other words, there must be some level of chaos, or room for the CNS to self-organize movement, to reach a goal.
When exercises offer no degrees of freedom (such as a heavy barbell lunge), the athlete’s CNS is in a “straightjacket,” and no motor learning is possible. -F Bosch
4 ways of adding variability
A. SAME BUT DIFFERENT
B. COMPLEX TRAINING
C. FATIGUE INDUCED LEARNING
D. INTRODUCING CHAOS
