Abstract:

By means of literature review, combination placements recording, mathematical statistics, this present paper analyzes the techniques of Xu Xin and Mizutani Jun, two top male table tennis players in the world, in their 13 matches from 2009 to 2016, aiming to reveal the characteristics and effects of their serving and receiving combination placements. The results show that: Xu Xin has obvious advantage when serving to placements 2 and 5; Xu Xin has the highest rate of effective attack in the third shot when combination placements 2-9 occur; Mizutani Jun's receiving targets Xu Xin's disadvantage in backhand position. Mizutani Jun's serving placements are mainly short-distance ones within the table, combined with moderate-distance ones beyond the table, and interspersed with bottom line long-distance ones; Mizutani Jun often loses when combination placements 6-9, 5-9, and 3-3 occur, and these are Mizutani Jun 's weakness; Xu Xin gains obvious advantage when serving to placement 9 with the technique of backhand twist, and loses more often when using the technique of forehand control.On the whole, Xu Xin scores lower in backhand position than in forehand and sideways positions, showing that there is an unbalanced tendency in his techniques. Suggestions: Xu Xin needs to get ready for placements 1, 6, 7, and 9 in the third shot of his service round ahead of time, and strengthen his training for combination placements 5-9, and 2-1; make clear Mizutani Jun's stroke mode at combination placements 6-9, 5-9, and 3-3 when in the receiving round; enhance his backhand rally ability, and optimize his pen-hold backhand attack technique.
