Delivery stride, Follow through

The delivery stride and swing, together, represent the moment when the bowler completes his bowling action and the ball is bowled. The stride is the landing of, firstly, the back, then the front foot, during which the delivery swing of the bowling arm takes place. The names do not change if, for any reason, the bowler does not release the ball.
The delivery stride is followed by what is called the bowler's follow-through - the further strides taken while decelerating from releasing the ball. Bowlers must take great care that they do not permit their follow-through to take them on to the Protected area of the pitch.
