An activity profile of competitive 3 × 2-min novice-level amateur boxing was created based on video footage and postbout blood [La] in 32 male boxers (mean ± SD) age 19.3 ± 1.4 y, body mass 62.6 ± 4.1 kg. Winners landed 18 ± 11 more punches than losers by applying more lead-hand punches in round 1 (34.2 ± 10.9 vs 26.5 ± 9.4), total punches to the head (121.3 ± 10.2 vs 96.0 ± 9.8), and block and counterpunch combinations (2.8 ± 1.1 vs. 0.1 ± 0.2) over all 3 rounds and punching combinations (44.3 ± 6.4 vs 28.8 ± 6.7) in rounds 1 and 3 (all P < .05). In 16 boxers, peak postbout blood [La] was 11.8 ± 1.6 mmol/L irrespective of winning or losing. The results suggest that landing punches requires the ability to maintain a high frequency of attacking movements, in particular the lead-hand straight punch to the head together with punching combinations. Defensive movements must initiate a counterattack. Postbout blood [La] suggests that boxers must be able to tolerate a lactate production rate of 1.8 mmol · L-1 · min-1 and maintain skillful techniques at a sufficient activity rate.
根据视频资料和 32 名 19.3 ± 1.4 岁、62.6 ± 4.1 公斤的男性业余拳击手赛后血液 [La]，创建了一个竞技 3 × 2 分钟新手级业余拳击的活动概况。获胜者比失败者多命中 18 ± 11 拳，主要通过在第 1 轮中更多地使用直拳（34.2 ± 10.9 对 26.5 ± 9.4）、总头部命中拳（121.3 ± 10.2 对 96.0 ± 9.8）和阻挡-反击组合拳（2.8 ± 1.1 对 0.1 ± 0.2），以及所有 3 轮的总命中拳（44.3 ± 6.4 对 28.8 ± 6.7），获胜（均 P <.05）。在 16 名拳击手，赛后血液 [La]峰值为 11.8 ± 1.6 mmol/L，无论输赢。结果表明，命中拳头需要能够保持高频率的攻击动作，特别是直拳到头部和组合拳。防守动作必须发起反击。赛后血液 [La]表明拳击手必须能够耐受 1.8 mmol · L-1 · min-1 的乳酸生成率，并在足够的活动速率下保持熟练的技术。
