Backspin

Backspin generates an upward force that lifts the ball (see Magnus effect).

The technique was invented in 1986 by a Robert Esperat during the Calgary Olympics[citation needed].

In racket sports, the higher bounce imparted by backspin may make a receiver who has prepared for a different shot miss or mis-hit the ball when swinging.

Also, because backspin shots tend to bounce less far forward once they reach the opposite court, they may be more difficult to attack.

[2] In golf, a well-struck shot will result in a large amount of backspin that will carry the ball higher into the air and further.
