Too many steps take the player too far from the T and by the time the shot is played, good or bad, there is no time to recover the T in order to cover the next shot. No space is created to allow good early racket preparation to maximize choice of shot. A succession of short steps leaves the player too close to the ball and again no space is created to allow correct choice of shot. When players fail to stretch to the shot when clearing the ball, they can not clear to the T fast enough. They will be busy trying to get away from the line of the ball, often moving back to the T via the wrong route.
Incorrect movement affects breathing.
Little steps force the short shallow breaths which accelerate tiredness. Short steps involve NO stretching patterns so there is no flow to the game, resulting in a rushed frantic style with little time to consider tactics. Technique is restricted causing errors to occur when under pressure. Incorrect movement can take players to a certain level if they have speed and a good eye for the ball. However it will stop them short when playing against a good astute tactician who will pull them in as surely as a fish on a line.
