Sažetak
In Kuala Lumpur, where the International Table Tennis Federation announced the replacement of the 38-mm ball with the 40-mm ball, it became evident that with decreased ball speed and rotation the players would have to devote more time to physical preparation. The difference between the physically better prepared players and the less prepared ones became apparent at the World Championships in Osaka. At the first World Championships played with the larger ball, the number of strikes per rally increased, which means that matches became longer and more demanding. Taking into account the strains of a two-week competition, it turned out that physical preparation, in particular additional strengthening of the shoulders area, would become a crucial factor of success. However, to design optimal physical preparation for table tennis players, it is essential to establish exactly which muscles of the shoulders area work harder due to the new ball. In our study, we tried to measure how much do myoelectric and neuromuscular impulses during forehand strike differ between using the 38-mm and the 40-mm ball. We analysed contraction of the muscles that are primarily involved in the forehand attack: m. pectoralis, m. deltoideus, m. biceps brahii, m. transversus abdominis and m. latisisimus. The measurements were taken on a professional table tennis player. Strength as well as duration of contractions of the abovementioned muscles was measured. The data were gathered and analysed both visually and quantitatively. The obtained measurements and graphical displays from the experiment indicate that in general, there is a minor difference in operation of the studied muscles between forehand attack strike using 38-mm and 40-mm ball.
