| 摘 要： | “东京2020奥运会”的推迟为国乒积极应对深入备战争取了时间,同时也对日本新星伊藤美诚为代表的现代颗粒打法带来了机遇。在传统三段法的基础上,运用卡方检验对伊藤美诚与国乒主力近期的比赛样本进行了统计和分析。伊藤美诚的发球落点和第3板抢攻方式对比赛结果无显著性影响,接发球击球技术对比赛结果有显著性影响,相持段最后1板的击球方式对比赛结果有非常显著性影响,同时验证了回合中按照时间序列所运用技术对于比赛效果的显著程度。发抢段中发球质量高,“中路长球”的威胁最大,“反手弹”和“正手拍”是第3板抢攻的主要手段,抢攻配套稳定,“正手拍”技术特点突出。接抢段中“反手侧喇”技术的运用丰富了接发球体系,但是过于凶狠的弹打技术以及对反手的依赖也会造成较多失分。相持段防守技术的运用是伊藤美诚的明显漏洞,直接导致了相持段得分率不高。建议在与其对阵中必须抢先上手、占据先机,提高击球质量以遏制颗粒打法“弹”“拍”等特长技术的威胁。

| Abstract: | The decision of postponing“2020 Tokyo Olympic Game”enables China National Table Tennis Team to make better preparation,and also provides opportunities for the modern pimpled rubber play,which is represented by Mima ITO,a new star in Japan.On the basis of three sections of index evaluation method,this paper uses the Chi-squared test to analyze the recent games between Mima ITO and athletes from China National Table Tennis Team.The placement of Mima ITO'service and her attack in the third stroke have no significant effect on the outcomes in matches while her receive techniques have a significant effect on the outcomes in matches.The stroke way in the rally part's last stroke has a great significant effect on the outcomes in matches.The significance of applying techniques according to time series in rounds is verified at the same time.In attack after serve phase,Mima ITO has a high quality in serve,especially the“center deep ball”,and her“backhand quick hitting”and“forehand attacking”is her main techniques in the third stroke.In attack after receive phase,the technique named“strawberry flick”enriches her service reception system.However,her over ferocious hitting style and her reliance on backhand caused many losses.Mima ITO has an obvious shortness in defense,which directly results in her low scoring in the rally part.It is suggested that athletes should attack first in the match against Mima ITO and improve hitting quality to curb the threat of pimpled rubber,especially the techniques of“hitting”,and“attacking”. |
