Abstract: A table-tennis training apparatus for training a player to apply spin to a table-tennis ball when using a racket to hit the ball. The table-tennis training apparatus has a ball holder for rotatably holding a table-tennis ball. When the ball thereon is hit by a racket, the ball holder pivots about an axis and an elastic structure coupled to the ball holder dampens the speed of the ball holder to prolong the contact time between the racket and the ball and consequently help the player to more clearly experience the feeling of applying spin to the ball and thus facilitate the player's training of applying spins to the ball.
