An activity profile of competitive 3 × 3-min elite-level amateur boxing was created from video footage of 29 Olympic final and semifinal bouts in 39 male boxers (mean ± SD) age 25.1 ± 3.6 y, height 178.3 ± 10.4 cm, and body mass 69.7 ± 16.5 kg. Boxing at this level requires the ability to maintain an activity rate of ~1.4 actions/s, consisting of ~20 punches, ~2.5 defensive movements, and ~47 vertical hip movements, all per minute, over 3 subsequent rounds lasting ~200 s each. Winners had higher total punches landed (P = .041) and a lower ratio of punches thrown to landed (P = .027) than losers in round 3. The hook rear-hand landed was also higher for winners than losers in round 2 (P = .038) and round 3 (P = .016), and defensive movements were used less by winners (P = .036). However, the results suggest that technical discrimination between winners and losers is difficult; bout outcome may be more dependent on which punch is "lucky" enough to be scored by the judges or who appears to be dominant on the day. This study gives both boxers and coaches a good idea of where subelite boxers need to aim if they want to become among the best amateur boxers in the world.
从 39 名男性拳击手（平均年龄 ± 标准差为 25.1 ± 3.6 岁，身高 178.3 ± 10.4 厘米，体重 69.7 ± 16.5 公斤）的 29 场奥运决赛和半决赛的视频中创建了一个精英业余 3×3 分钟的比赛活动概要。在这个水平上拳击需要有能力保持约 1.4 次/秒的活动率，包括每分钟约 20 次出拳、2.5 次防守动作和 47 次垂直臀部动作，所有这些动作都要在随后的 3 轮持续约 200 秒。在第 3 轮比赛中，获胜者的总出拳次数更高（P =.041），出拳次数与命中次数的比例更低（P =.027）。在第 2 轮和第 3 轮比赛中，获胜者的后手钩拳也比失败者更高（P =.038 和 P =.016），而且获胜者使用的防守动作更少（P =.036）。然而，结果表明，在获胜者和失败者之间进行技术区分是困难的；比赛结果可能更多地取决于哪一拳“幸运”到足以被裁判计分，或者谁在当天看起来更具优势。这项研究让拳击手和教练都很好地了解了次精英拳击手如果想成为世界上最好的业余拳击手之一，需要在哪些方面努力。
