Female boxing debuted at the 2012 London Olympic Games. To better understand the performance aspects of the sport, video footage of eighteen 4 × 2-min bouts were analyzed. The boxers involved in the competition were of an elite level (mean ± SD), age 26.4 ± 4.6 y, height 169.3 ± 6.2 cm, and weight 60.3 ± 10.0 kg. Analysis revealed an activity rate of ~1.6 actions/s, including ~16 punches, ~3.3 defensive movements, and ~63 vertical hip movements, all per minute, over the 4 × ~132-s rounds (R). A 2 × 4 (outcome × round) ANOVA with repeated measures over the rounds was used to analyze the data. Winners maintained a higher activity rate in round 1 (R1) and R2; a higher movement rate in R2, R3, and R4; and an increased punch accuracy including the ratio of total punches to punches landed in R3 and air punches as a percentage of punches missed in R1 and R3. Specific techniques that discriminate between successful and unsuccessful female amateur boxers include the straight rear-hand and body punches, higher for winners in R1, as well as uppercut punches and defensive foot movements, higher for winners in R4. Findings highlight the current demands of elite amateur female boxing. These data will be useful for those designing training programs and may also be useful for guiding sport-specific fitness testing.
女子拳击在2012年伦敦奥运会上首次亮相。为了更好地了解这项运动的表现方面，分析了18场4×2分钟比赛的视频片段。参与比赛的拳击手均为精英水平（均值±标准差），年龄26.4±4.6岁，身高169.3±6.2厘米，体重60.3±10.0千克。分析显示，在4×约132秒的回合（R）中，活动速率约为每秒1.6次动作，包括每分钟约16次出拳、约3.3次防御动作和约63次垂直髋部动作。使用2×4（结果×回合）方差分析，并对回合进行重复测量来分析数据。获胜者在第1回合（R1）和第2回合保持较高的活动速率；在第2、3和4回合保持较高的动作速率；并且出拳准确率提高，包括第3回合总出拳数与命中拳数的比率以及第1和第3回合空拳占未命中拳的百分比。区分成功和不成功的女子业余拳击手的特定技术包括直后手拳和身体拳，在R1中获胜者的此类拳数更多，以及上钩拳和防御性脚步动作，在R4中获胜者的此类动作更多。研究结果突出了精英业余女子拳击的当前要求。这些数据将对设计训练计划的人员有用，也可能有助于指导特定运动的体能测试。
