In modern volleyball, co-spiker, as a main component in various tactics, has become the core of the team’s offensive and defensive. In this paper, by taking the co-spikers’ techniques and tactics in men’s volleyball competitions among China, America, Brazil, Russia and Italy in Beijing Olympic Games as the object, by analyzing the video material from the nine men’s volleyball competitions in Beijing Olympic Games, by applying document data, video observation, mathematical statistics and comparative analysis, this thesis carried out a quantitative analysis about the tactical application effects during the men’s volleyball games between China’s co-spikers and the top four co-spikers in the world, then gains the advantages and disadvantages of China’s co-spikers.According to the research and analysis, we find out that Chinese co-spikers are younger. Their body heights, spike heights and block heights have been in the world-class level. However, their body weights are lighter and weaker. The average body height is over 200cm.The study also finds out that the individual attack tactics of Chinese co-spikers are various. The spike with short low set is the key for Chinese and American teams, the quick spike from close set for Brazilian team, and the combination of spike with short low set and quick spike from close set for the Russian and Italian teams. The spike with short low set in Chinese team is in high level, but compared to the strong teams in the world, there is still a gap in the quick spike from close set. Since Chinese co-spikers often make mistakes in the games. Referred to the offensive cover, Chinese co-spikers did a perfect job by applying the echelon offense, wedge-in attack, surrounding attack in the front. No matter it is the cover of spike with short low set or the cover of the quick spike from close set, the co-spikers did a better job in covering the back-row than the front-row. They did most ideal in covering the back six players’attack.Chinese men co-spikers are less aggressive in blocking, while the Russians and Americans have very strong aggressivity in each position. There is a serious problem that Chinese co-spikers often leak the blocks, especially in the second and fourth positions, which reflects that Chinese co-spikers are very weak and make many mistakes in blocking. In a whole, co-spikers in American team perform well in every aspect.At present, co-spikers mainly apply jumping power serve and jump floating serve, the latter one preferred by the most. Chinese team made many mistakes in the serve. co-spikers perform poorer in the pass. Their overall defensive abilities are weaker. Compared with the Top Four blockers in the world, Chinese co-spikers play the ball defensively low quality, and have a high rate of making mistakes.
