对日本乒坛新秀伊藤美诚主要技术指标统计分析与研究

The Main Technical Indicators Statistical Analysis and Research for Japan's Table-tennis Rookie Mima Ito

运用文献资料、录像统计、四段指标评估等研究方法,对日本乒坛新秀伊藤美诚在2015年至2016年3月以来的八场国际重大比赛视频进行观察和统计,并对主要技术指标进行细化研究。结果表明:在发球轮上,伊藤美诚发球质量较高,直接得分效果明显,但在个别场次第三、第五拍失分较多,主要是正手抢攻质量不高,击球不稳。在相持I段上整体技战术运用效果较好,占据一定优势,近台相持球要好于中远台相持球。在接球轮上,伊藤美诚接发球技术过于单一,控球技术不够严密,导致接抢段(第二、四拍)乃至相持Ⅱ段(第八拍)技术失分较为严重,出现被动防守局面。在四段技术指标上伊藤美诚整体出现得分率低,使用率过高的现象。通过技术诊断,伊藤美诚在发球轮是主要得分手段,得分贡献率要稍好于对手,但差异不太显著,导致伊藤美诚整体竞技实力不足主要是在接球轮,也是造成比赛失利的重要原因。

This paper is about the main technical indicators statistical analysis and research of Japans table-tennis rookie Mima Ito,which is based on the observation and statistics of Itos eight major international games video from march in 2015 to 2016,and the detailed study on the main technical indicators,by means of literature methods,video statistics,four index evaluation method,etc.Mima Ito got scores more easily with her high quality serve in combination with drop shot and long ball,but she lost some scores at the third and fifth shot in some match because of her less powerful forehand rushing attack and relying too much on the backhand.In the stalemate I,Ito took an advantage with the good use of overall technique and tactics.Although her speed gave her some priority in the close-table forehand attack,her hit was not strong enough in the middle-long table.Ito lost the edge and was in a passive defense situation due to her single receive technique and loose ball control.It means Ito lost points seriously（the second,fourth shot）and stalemate II（the eighth shot）,which is also the important attribution of the defeat.Mima Ito got a overall low scoring average with a high usage rate of four technical indicators.It is found that Itos scoring contribution rate surpassed her rivals a little when she served（serve,stalemate I）and weakened her whole competitive strength when she received（receive,stalemate II）.
