Kinematic analysis of forehand strike in table tennis executed with ball of two different sizes

The new matertials used for rackets have had a major impact on development of table tennis technique over the last twenty years. To a certain extent, they have also dimished the interest and joy of the spectators. The novelties introduced by the International Table Tennis Federation in las three years call for a new approach to technical, tactical and physical preparation. The introduction of the larger (40-mm) ball changed the way some strikes are executed. Harder strikes and slower ball demand adaptations of technique and better physical preparation from the players. The aim of our study was to analyse kinematic characteristics of forehand strike using the 38-mm and the 40-mm ball. Kinematic analysis enables precise identification of any strike technique and hence also comparison of different techniques. The analysis was carried out using the Elite system, which is designed for recording and evaluating kinematic parameters. This enabled us to calculate the differences in forehand strike technique caused by replacing the 38-mm ball with the 40-mm one. The comparison of selected kinematic prameters proved that differences arose in the amplitude of forehand strike of the tested player due to increased ball size. The gathered data should facilityte planning of the training process, especially for promising young players.
