This immediate slow down or disruption to performance can understandably be alarming to the advanced athlete... who expects corrections to come easily and quickly, at virtually no cost. But this may be a consequence of a short-term viewpoint and some lack of understanding of how the brain works. In the long-term view, we understand that neural circuits have to go through a process when being altered - the more complex the change and the more complex the conditions will be for its ultimate application, the more patient the athlete will need to be with the retraining process.
