Results and Analyses Single Competition Chinese team took part in five singles matches after 2015 Su Cup badminton tournament 1/8 finals, in which there are three games of men’s singles and two games of women’s singles. Table 1 shows the numbers of contestants’ appearances. Tables 2 and 3 show the statistical results of initiative scores and initiative loses during the games. Men’s singles quarter-final is between Chen Long from China and Jonathan from Indonesia. From the active scoring competition results in Table 2, Chen Long and Jonathan equal in offensive capability. The two sides are both comprehensive technical players; scored only 1 point in smashing up, which indicating both sides take good control in return ball quality. Chen Long scores 2 more points in backcourt kill and 2 more points in flapping, while Jonathan got 2 more points in near-net ball. Both sides vary little and their overall score is 11 to 9. The two sides in terms of losing the initiative reflect a larger gap. Chen Long initiative loss was 15 points less than his opponent, which is about half of his opponent’s initiative loss. Chen Long has a strong initiative in scoring, moves fast, has more comprehensive techniques [5]. Although his characteristics were not shown in initiative scoring, he succeeded in forcing his opponent to commit more errors and semi-coercive force turnovers. Lin Dan mainly scores in killing the ball in the frontcourt and backcourt. 14 out of 20 initiative scores are taken from backcourt killing, which accounts for 70%. In contrast, his opponent Ueda Takuma’s way in taking initiative scorers are more balanced. Lin Dan active scores 5 points more than his opponent. However, it can be seen in Table 2, Lin Dan in this game makes full use of his advantages by killing the ball, lofty ball oppressing his opponent to take defensive state which cause him to hit the ball into the net or out of bounds. Lin Dan scrambled by paving the way to reverse the situation to score Several times through his active defense. Ueda Takuma’s lost points mainly due to forced errors [3, 4, 6]. Overall, Lin Dan active lost 9 points less than the opponent, which are mainly unforced errors and semi-coercive mistakes. Unforced errors including three boundaries ball misjudgments and a tee shot. Lin’s other lost are net-balls or out of bounds (including the edges and the bottom line) during the transition between attacking and defending under the balanced state. Different from finals the men’s singles 1/8 finals, killing the ball is the main means of active score, Lin Dan’s initiative scores are more balanced. During the race, Lin Dan has reservations, and did not take more physical exertion to kills. In terms of losing the initiative, Lin Dan has very little stress errors. When the game just begins, the Germany player’s good state with focused attention caused some pressure on Lin Dan and made him commit some semi-coercive mistakes. China sent Li Xuerui play the two singles matches. Women’s singles quarter-final match Li Xuerui plays against Manu Buti from Indonesia and Manu Buti scores ahead in the beginning. Dramatically, Manu Buti got injured accidentally during the race and could not finish the race, which gave Li Xuerui the chance to win. Li’s women’s singles final opponent is Japan’s Akane Yamaguchi. Li’s second game is very tough for her and she won finally in the playoff. In active score, Li got 17 points, only 1 more than her opponent. Akane Yamaguchi’s physical fitness is better and she could still play backcourt kills after the game with good quality. On the other side, Li won 3-points-advantage through net smash, hook right corner and near-net ball. Li also plays better in lessing the active lost points. Relying on her skillful techniques, Li forces her opponent to commit turnovers and semi-coercive coercive mistakes repeatedly, resulting in more of the ball out of bounds and into the net error.

Conclusion 1) This essay mainly analyze the statistics of the active scores and active losses of all the last Chinese team games after the 1/8 finals. Of all the games only in the men’s double finals’ game both sides got more points in active scores than active loss. Most games the players got more points in active losses. 2) When the final scores are quite close, like men’s doubles final and men’s doubles 1/4 final, players are more easily to commit faults in serving and receiving balls under great stress. While in other cases, like men’s single 1/8 final, players seem to tend to commit faults in misjudgments in boundaries. Single game Players lose more points in return ball out of boundary than return ball under the net. On the contrary, double game players lose more points in return ball under the net. 3) Back court kill is the main way of active scoring. Of all the 10 games only in one women’s single game most points are not gained from back court kill. Smashing is the most aggressive way to attack, and consumes a lot of physical energy. When the two sides get a very big gap in scoring, the points gained by smashing would not be very much. Therefore, it is very wise to choose the proper way to attack according to the situation. 4) In women’s singles quarter-finals, the Indonesian player quit the game because of the accidental injury. In selecting the right competitors, the team leader not only needs to consider the contestants competitiveness, but also need to consider their physical situation. 5) 9 players joined in the last 10 contest since the 1/8 finals. Among all the players, Fu Haifeng attended 3 games. Compared with last Sue Cup, most players are older, accordingly 4 years older in men’s single, 1 year older in women’s single, 5 years older in men’s double and 3 years older in women’s double. Some excellent players have to face the aging and physical energy problem.
