Topspin

The harder-to-learn

4 phases in a topspin curve

 topspin stroke has a smaller influence on the first part of the ball-curve. Like the backspin stroke, however, the axis of spin remains roughly perpendicular to the trajectory of the ball thus allowing for the Magnus effect to dictate the subsequent curvature.

After the apex of the curve, the ball clearly dips downwards as it approaches the opposing side, before bouncing. On the bounce, the topspin will accelerate the ball, much in the same way that a wheel which is already spinning would accelerate upon making contact with the ground.

Again, the most significant change appears when the opponent attempts to return the ball (with a smooth, pimples inwards rubber). Due to the topspin, the ball jumps upwards and the opponent is forced to compensate for the topspin by adjusting the angle of his or her racket. This is commonly known as "closing the racket".

The speed limitation of the topspin stroke is minor compared to the backspin stroke. This stroke is the predominant technique used in professional competition because it gives the opponent less time to respond.

In table tennis topspin is regarded as an offensive technique due to increased ball speed,

Topspin is the least common type of spin to be found in service at the professional level, simply because it is much easier to attack a top-spun ball that is not moving at high speed
