Differences in GRF executing forehand topspin with different balls

In modern table tennis most international competitors favour the forehand top spin as most favourable attacking stroke. Technically correct performance of top spin strike and its power is, of course dependable on the player's knowledge, his motor abilities, his morphological characteristics and especially on his physical preparation. Perfectly performed top spin has to be initiated from the legs and an activation of a proper kinetic chain is therefore the most important part of this stroke. The aim of this study was to find out if during the forehand top spin strokes with balls of different sizes there are differences in the ground reaction force (GRF). Lack of strength in player's legs can namely produce over time a wide range of injuries. The comparison of selected parameters proved that the observed differences increase due to increased ball size. In order to hit the ball with more spin, the player must use wider movement path to position a ball on his rackett. As bigger ball has at the same speed less spin, players need to execute top spin with more power. The gathered data should fascilitate planning of the physical preparation training process of table tennis players.
