Why, in the face of soft elasticity, because the club no elasticity soft ground because of the bouncing ball hit that moment also can produce deformation, much of the strength to absorb the force, so elastic ball bouncing back in the process of getting energy is not so much to hit down before the results will play is not high, finally stopped, and table tennis racket's surface by comparison, a rubber ball hit in the impact of table racket and bounce effect is different, bouncy ball movement by its elastic deformation, deformation more formidable play, the higher the
