基于四段指标评估法对孙颖莎与伊藤美诚比赛的技战术分析

Analysis on the Techniques and Tactics of Competitions between Sun Ying-sha and Mima Ito based on Four Phases Evaluation Theory

本文运用录像观察法、四段指标评估法、数理分析法对孙颖莎与伊藤美诚2019年的五场国际比赛进行技战术分析。结果表明:整体来看,孙颖莎技战术发挥较好,技术全面,无明显薄弱环节,其中发抢段和接抢段是致胜的关键;发抢段方面,以发反手底线长球结合短球为主,第三板多为正反手拉/带和正反手冲,反手位落点较多,质量高,但稳定性不足;接抢段方面,接发球失误偏多,劈长至反手底线的战术有一定效果,第四板以反手拉/带技术为主,有化被动为主动的能力,但被动时落点意识下降;相持段方面,拉/带和冲是主要技术,在反手相持中伺机进攻为主要战术,与对手势均力敌。

The study analyzes techniques and tactics of five international competitions between Sun Yingsha and Mima Ito in 2019 by using methods of video observation,four phases evaluation theory and mathematical statistics.Results show that Sun Yingsha is relatively well-rounded,performing well both in techniques and in tactics without obvious weaknesses and the phases of serve attack and receive attack are key points of winning as a whole;in serve attack phase,serving long balls to backhand positions is the major tactic,with coordinating with short balls;forehand and backhand loop drive are the main techniques in the third stroke,with more backhand ball placement;quality of balls is rather high but the stability is not adequate;in receive attack phase,there are relatively more misses made in receiving balls;using long heaving-spin push technique to backhand positions is effective;backhand loop drive is the main technique in the fourth stroke;Sun Yingsha has the ability to transfer from passive status to active one but the placement awareness is not good when being in passive status;in counterattack phases,loop drive and smash are major techniques whereas looking for chance to attack when being in backhand counterattack is the major tactic,with the two players having similar competence.
