探討奧運新增桌球項目之世界頂尖混合雙打三段技術分析

Analysis of Three Stage Skill in the World's Top Mixed Doubles Table Tennis Event Introduced at the Olympics

目的：探討王楚欽、孫穎莎在2021年頂級賽事中的三段技術分析。本研究目的如下：一、分析王楚欽、孫穎莎發球搶攻段之得分率與使用率。二、分析王楚欽、孫穎莎接發球搶攻段之得分率與使用率。三、分析王楚欽、孫穎莎相持段之得分率與使用率。四、分析王楚欽、孫穎莎比賽中三段技術總體之得分率與使用率平均值表現與評估。方法：本研究以王楚欽、孫穎莎為研究對象，且透過網路影片觀看2021年中王楚欽、孫穎莎三場國際比賽進行分析，運用中國學者吳煥群、李振彪(1990)所發表的桌球三段技術分析紀錄表進行紀錄與分析，並且得知研究結果。結果：孫穎莎、王楚欽三場比賽中的發球搶攻段的使用率為27%，表現評估為及格；得分率為54%，表現評估為不及格。接發球搶攻段使用率為37%，表現評估為及格；得分率為35%，表現評估為及格。相持段的使用率為36%，表現評估為不及格；得分率為63%，表現評估為優秀。結論：孫穎莎、王楚欽在發球搶攻段、接發球段沒有辦法有效的得分，因此才會將比賽走向相持段，而透過結果顯示孫穎莎、王楚欽兩位選手在相持段的得分率為優秀，所以表示如果能夠將比賽延長至相持段，那會是這兩位選手贏球的關鍵之一。建議：一、孫穎莎、王楚欽的相持段的能力相比其他選手來說較為突出，若未來選手遇到相持段能力較好的對手，可以選擇在前四板搶攻的質量及落點打出來，這樣才有機會破壞對手的節奏，獲取主動權。二、未將發球旋轉列入研究範圍，建議未來可以針對孫穎莎、王楚欽兩位選手進行研究及討論，是否在技戰術上有些差異。三、未將接發球技術列入研究範圍，例如：擺、擰、挑、劈，建議未來可以針對孫穎莎、王楚欽兩位選手進行研究及討論，是否在技戰術上有些差異。

Purpose: The aim of this study is to analyze the three technical stages of Wang Chuqin and Sun Yingsha in the top tournaments of 2021 mixed doubles table tennis. The objectives are as follows: 1) Analyze the scoring rate and usage rate of the serving and attacking stage for Wang Chuqin and Sun Yingsha. 2) Analyze the scoring rate and usage rate of the receiving and attacking stage for Wang Chuqin and Sun Yingsha. 3) Analyze the scoring rate and usage rate of the neutral rally stage for Wang Chuqin and Sun Yingsha. 4) Evaluate and compare the average scoring rate and usage rate of the three technical stages during their matches. Methodology: The study focuses on Wang Chuqin and Sun Yingsha, and it involves analyzing three international matches played by them in 2021 through online videos. The technical analysis record form proposed by Chinese scholars Wu Huanqun and Li Zhenbiao (1990) is utilized for data collection and analysis, yielding the research results. Results: In the three matches, the usage rate of the serving and attacking stage for Wang Chuqin and Sun Yingsha is 27%, with a performance evaluation of ''pass. '' However, the scoring rate is 54%, resulting in a performance evaluation of ''fail. '' The receiving and attacking stage has a usage rate of 37% and a scoring rate of 35%, both receiving a performance evaluation of ''pass. '' The neutral rally stage has a usage rate of 36% and a scoring rate of 63%, with performance evaluations of ''fail'' and ''excellent,'' respectively. Conclusion: Wang Chuqin and Sun Yingsha struggle to score effectively in the serving and attacking stages and the receiving and attacking stages, which often leads the matches to the neutral rally stage where they excel. The results indicate that their scoring rate in the neutral rally stage is excellent, suggesting that prolonging the matches to this stage could be a key factor in their victories. Recommendations: 1) Considering Wang Chuqin and Sun Yingsha's exceptional performance in the neutral rally stage compared to other players, they could focus on attacking the opponent's weak points during the first four strokes to disrupt their rhythm and capitalize on their strengths. 2) Future research should consider including the study of serving spin as it may reveal differences in technical and tactical approaches for Wang Chuqin and Sun Yingsha. 3) Additionally, investigating their receiving techniques such as push, flick, chop, and lob could offer further insights into their strategies and performances.
