Table tennis diameter changes to competition influence quantitative analysis

Author(s): Naiming Wang

Use probability theory and mathematic statistics method respectively to make analysis of high level table tennis players using small ball and big ball to play singles data in international major sports competitions after changing table tennis, from which it puts emphasis data statistics and handling with athlete’s every one point hitting round numbers when using small ball to proceed competition and using big ball to proceed competition. The paper gets that big ball era audience appreciation quality has some improvements by comparing with small ball era and athlete competition experience quality has also been improved. On the premise of ensuring that let table tennis normally fly across net without falling out of table when hits table tennis every time, the paper assumes an athlete hitting optimum distance. Meanwhile, by Newton classical mechanical computing, it gets flight time increment; and by time increment and diameter increment relations, it gets table tennis diameter increment and flight time increment function relationship. By function relationship, the paper discusses table tennis best diameter.
