You are basing this assertion on what, precisely? Attention, posture, pattern memory and state-estimation all strongly impact every level of athletic performance. This has been studied extensively. If I had a better term to describe these aspects of neural organization I would use it. I like mental representation because a coach on the ground can impact development of an athlete by providing a picture of what to focus on during performance, and this representative picture directly improves the signal to noise ratio for the athlete.
